7 Math Manipulatives for your Digital Toolkit

Seven FREE and fabulous math apps for your digital toolkit. Geoboard by The Math Learning Center (a nonprofit organization dedicated to K – 12 education) is a FREE app that turns your iPhone/iPad into a virtual geoboard. Geoboards can be used as tools to teach mathematical concepts such as polygons, perimeter, area, line segments, angles, congruent shapes, symmetry, fractions, etc. Shapes are created by stretching bands on the geoboard’s pegs. There are 5 colors of bands in the iPhone version and 8 in the iPad version. There is also a tool to fill in shapes. On the iPad version, you can switch from the standard 25 peg board to a 150 peg board to create more complex shapes. This is a great app with the potential to be used in so many ways. FREE for the iPad, Virtual Manipulatives contains math manipulatives for teaching fractions, decimals, and percents. Included are tiles/circles divided into halves, thirds, fourth, fifths, sixths, eighths, tenths, and 12ths AND their corresponding decimals and percentages! The manipulatives are color coded across the settings so that 1/2 is blue as is .50 and 50%. Kids drag tile pieces onto the work area to compare fractions/decimals/percentages. In the settings you can change from tiles to circles, make the pieces transparent, and hide the numbers on the pieces. Completed work can be easily saved to photos. Finding equivalent fractions has never been so slick – WOW!!

Common Core Standards met:

• 3.NF.3 – Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
• 4.NF.1 – Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.  From the National Council of Teachers of Mathematics comes a FREE app called Equivalent Fractions. Kids create equivalent fractions by dividing and shading squares or circles. Circles can be divided into 24ths. Squares can be divided into 144ths. In the play mode, a fraction is shown and kids must create 2 additional fractions that are equivalent. All 3 fractions must have different denominators. The app also places the fractions on a number line – a great visual for comparing! There is also a “build your own” mode which would be fabulous to use for guided exploration & practice. Kids could also use this section as a virtual manipulative when working independently. This app is an excellent resource for the classroom !!

Explain why the fractions are equivalent, e.g., by using a visual fraction model.  Another FREE app is Counting Board HD, a colorful number grid that can be used to help kids learn basic number concepts. The app is advertised as being suitable for 2 to 4 year olds but it can also used with older students. I frequently used number grids with third graders. Number grids help kids see patterns and visualize math concepts. With younger children, the app can be used for counting to 100 – by ones, fives, tens. Younger kids can also learn basic addition and subtraction by using the app to count up or count back. With older kids, number grids can be used to teach: greater than and less than, how to find missing addends, place value concepts, skip counting, and more! The app can be used with the numbers showing or hidden and the pronunciation can be on or off. The app simple to use, visually appealing, and useful for so many math lessons. I love this app! It’s so much easier than dragging out the laminated number grids and counters. 🙂

Common Core Standards met:

• K.CC.1. Count to 100 by ones and by tens.
• K.CC.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
• 1.NBT.5. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
• 1.NBT.6. Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
• 3.OA. 9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. Number Line, by the Math Learning Center is a fantastic FREE app that will help kids visualize number patterns and understand number operations. The app is well-designed with several useful features. The number line can be set by ones, twos, fives, tens, twenty-fives, and hundreds. It can also be customized to show multiples of any whole number from 1 to 100. This feature is perfect for skip counting and/or for visualizing multiplication. The app permits kids to add and manipulate forward & backward jumps – a great feature for teaching addition & subtraction. This feature also helps kids visualize multiplication as repeated addition of the same number and division as repeated subtraction of the same number. Teachers are able to hide or reveal numbers on the number line. This feature can be used to challenge kids to apply what they know in order to figure out the missing number/numbers. Teachers can also use this feature to teach kids how to solve more difficult patterns that are missing several numbers; such as 4, __, __, 16.  Kids can use the drawing tools to show what they know. They can write equations and expressions with the text tool. They can screen shot their work and use it as an exit slip after a lesson. Add this one to your virtual toolkit today – “seeing math” helps kids understand it. 🙂 Free Protractor from Pongo Soft is another tool that you may want to add to your digital toolbox. The angle can be set in two ways: by touching the pointer or by entering the angle on a keypad. Once the angle has been set, it can be locked to avoid movement of the pointer when taking readings. Kids can also use this tool to see how many degrees are in a straight angle and a right angle or to discover the difference between an acute angle and an obtuse angle. They can easily see what combinations of angles are equal to a straight angle.  Since the app is free, there is some advertising across the top. Check out this FREE educational app for your geometry students. FREE educational app – Number Pieces from Math Learning Center. This educational app is the digital version of place value manipulatives, hands-on tools used to help students understand place value. Using the place value models within this app, kids can visualize the process of adding and subtracting ones, tens, and hundreds. The app has a function that permits kids to break apart pieces or join them together. This feature is fabulous for kids who need concrete examples. The app also includes expanding edge pieces which can be used to introduce arrays. Other features of the app include: three colors for identifying groups, drawing tools for labeling, a text tool for writing number sentences, zooming & scrolling for larger numbers. Thanks to the Math Learning Center, teachers & their students have another great app to add to their digital toolkits!

This FREE app just keeps getting better and better because the developer encourages teacher input. How wonderful is that – a developer willing to listen to teachers’ needs!

Oh No Fractions! is a great FREE iPhone/iPad app for comparing and exploring fractions. The educational app is simple to use – kids just swipe to the right or the left to indicate whether one fraction is “greater than” or “less than” or “equal to” a second fraction. As they work, kids can tap above each fraction to see if it can be reduced/simplified – a great feature. But, one of the best features of this app is the “peek”/”prove it” feature. Kids can use a manipulative to “peek” at an answer before they commit to it or they can use the manipulative to “prove” their answer later. This feature is fabulous because it allows the child to visualize his/her answer. Kids can also use this app to practice finding the common denominator. Then they can use it for addition, subtraction, multiplication, and division of fractions. The app also generates corresponding decimals/percentages for each answer. What a great tool for helping kids to understand fractions!! It’s no wonder that it received the 2013 Children’s Technology Review Editor’s Choice Award.

From England and currently \$1.99 –  Squeebles Fractions, an app for the iPhone/iPad that is designed to teach fractions to 7 – 11 year olds. The Squeebles want to enter a cake making contest but their ingredients have been stolen by the Math Monster. By working on the app’s 4 games, kids help the Squeebles earn back their ingredients. In Piece of Cake, kids drag the fractional part of a cake to a Squeebles when he asks for it. The easy mode covers halves, fourths, thirds. The hard mode cover fractions to tenths. In Tricky Pairs, kids have to match pairs of equivalent fractions. In the easy mode they match 4 pairs and in the hard mode they match up to 9 pairs. Think Big has kids feeding cake to the Squeeble that calls out the biggest fraction. The easy mode covers halves, fourths, thirds. The hard mode cover fractions to twelfths. Super Sums requires kids to add fractions as quickly as they can and has three levels of difficulty. After earning ingredients, kids can create cakes and enter them in The Cake Show – fun! Another great thing about this app is that you can have more than one player. My only concern is that the easy mode of Piece of Cake requires kids to know some equivalent fractions – for example, it asked kids to pick 3/4 of a cake divided into 8 pieces, 1/3 of a cake divided into 6 pieces, etc. I wish it would have required a basic knowledge of fractions in the easy mode then moved on to equivalent fractions in the hard mode. This app is cute, fun, and provides great practice for a wide spectrum of kids.

12 Fun Apps for Learning Math Facts

Let’s face it – getting kids to learn their math facts can be a challenge. But once they know them, they know them forever. The process of “doing math” becomes more efficient and less frustrating when kids know their facts. Luckily there are plenty of fun apps that can help kids become “math fact” proficient. All of these apps are FREE or were “FREE for a limited time” when I reviewed them. Check them out – they’re all great!

You can follow my blog  if/when they become FREE again. Enjoy!! 🙂 Sushi Monster is a FREE educational app for the iPhone/iPad developed by Scholastic. It helps kids practice, reinforce, and extend their knowledge of math facts. There are 12 levels of play – 7 addition levels and 5 multiplication levels. A chef places numbered plates of sushi on the counter. Kids have to combine the numbers on the plates to reach the target number (worn by the sushi monster). If the combination is correct, the monster gobbles up the sushi. If it is wrong, the monster throw a tantrum. Each round has 14 target numbers. Successfully completing one level unlocks the next. As kids progress through the levels they are expected to extend their thinking beyond the basic facts. At each level a strategy is provided to help kids succeed. This educational app provides a lot of practice and kids will love the silly sushi chef!

This app was FREE, now \$.99.  It helps kids practice their basic facts for addition, subtraction, multiplication, and division. First kids choose numbers (1-12) to work with, then the math operation/operations. The app generates practice in 2 modes: answer mode (enter the answers & get feedback) or flashcards mode (answer verbally then check). The game has no built-in sounds but there is positive reinforcement written at the top of the page. If a child misses a problem, it shows the correct answer. What I really like about this app is the ability to choose specific numbers to work on. Facts can be practiced in the order they are taught. I also like the ability to choose more than one operation to practice – it makes kids pay attention to the signs of operation and see the relationships between operations. This app is simple but effective – if you loaded this app on your iPhone, kids could easily practice flashcards on their way to after school activities. 🙂

The object of the game is to stop Dr. Odd’s quest to eliminate the world’s even numbers. In order to do so, kids must complete 105 missions by solving equations. Missions can be selected based on a child’s skill level and/or the operation (+, -, +/-, x, ÷, x/÷  or +/-/x/÷).  Of course, time is of the essence so kids have to answer problems in 60 seconds or less. By doing so, they lock doors along their escape routes. And as they complete missions, they earn the gear of a seasoned spy. What a great game – I love how the app integrates math practice into a really cool game for kids. I especially like the modes which permit kids to practice multiple operations at a time. It makes kids pay attention to operation signs and quickly switch their thinking. What a fun way for kids to practice facts and meet CCSS!

Was FREE for a limited time, currently \$1.99 – Bubbling Math, an educational app for the iPad helps students in grades 1 – 4 become proficient in basic math skills – addition, subtraction, multiplication, division. In the Task Configuration section of the app, parents/teachers choose the operations & the levels of difficulty (easy, medium, hard, expert). Descriptions tell specifically what kinds of problems are included in each level. The ability to customize what a child needs to practice makes this app very powerful. Another plus is that the levels can be set differently for each operation. The other powerful section of this app is the “parents section” where a child’s progress is reported by the date, the operations and levels practiced, the number right & wrong, the specific problems missed, and percent correct.

As for the actual game – there are 9 levels that unlock as the child makes progress. There are trophies awarded for doing well. The graphics and music are nicely done. The speed of the game can be adjusted  – slow, normal, fast. But…what makes this app stand out is the ability to truly personalize it. Unfortunately, I don’t think the app tracks more than one child’s data. The data can be reset but the results for the first child would be lost. Regardless, this app is great!

7 Math Manipulatives for your Digital Toolkit

Happy Spring!  Here are seven FREE math apps for your digital toolkit. Geoboard by The Math Learning Center (a nonprofit organization dedicated to K – 12 education) is a FREE app that turns your iPhone/iPad into a virtual geoboard. Geoboards can be used as tools to teach mathematical concepts such as polygons, perimeter, area, line segments, angles, congruent shapes, symmetry, fractions, etc. Shapes are created by stretching bands on the geoboard’s pegs. There are 5 colors of bands in the iPhone version and 8 in the iPad version. There is also a tool to fill in shapes. On the iPad version, you can switch from the standard 25 peg board to a 150 peg board to create more complex shapes. This is a great app with the potential to be used in so many ways. FREE for the iPad, Virtual Manipulatives contains math manipulatives for teaching fractions, decimals, and percents. Included are tiles/circles divided into halves, thirds, fourth, fifths, sixths, eighths, tenths, and 12ths AND their corresponding decimals and percentages! The manipulatives are color coded across the settings so that 1/2 is blue as is .50 and 50%. Kids drag tile pieces onto the work area to compare fractions/decimals/percentages. In the settings you can change from tiles to circles, make the pieces transparent, and hide the numbers on the pieces. Completed work can be easily saved to photos. Finding equivalent fractions has never been so slick – WOW!!

Common Core Standards met:

• 3.NF.3 – Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
• 4.NF.1 – Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.  From the National Council of Teachers of Mathematics comes a FREE app called Equivalent Fractions. Kids create equivalent fractions by dividing and shading squares or circles. Circles can be divided into 24ths. Squares can be divided into 144ths. In the play mode, a fraction is shown and kids must create 2 additional fractions that are equivalent. All 3 fractions must have different denominators. The app also places the fractions on a number line – a great visual for comparing! There is also a “build your own” mode which would be fabulous to use for guided exploration & practice. Kids could also use this section as a virtual manipulative when working independently. This app is an excellent resource for the classroom !!

Common Core Standards met:

• 3.NF.3 – Explain equivalence of fractions and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.  Another FREE app is Counting Board HD, a colorful number grid that can be used to help kids learn basic number concepts. The app is advertised as being suitable for 2 to 4 year olds but it can also used with older students. I frequently used number grids with third graders. Number grids help kids see patterns and visualize math concepts. With younger children, the app can be used for counting to 100 – by ones, fives, tens. Younger kids can also learn basic addition and subtraction by using the app to count up or count back. With older kids, number grids can be used to teach: greater than and less than, how to find missing addends, place value concepts, skip counting, and more! The app can be used with the numbers showing or hidden and the pronunciation can be on or off. The app simple to use, visually appealing, and useful for so many math lessons. I love this app! It’s so much easier than dragging out the laminated number grids and counters. 🙂

Common Core Standards met:

• K.CC.1. Count to 100 by ones and by tens.
• K.CC.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
• 1.NBT.5. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
• 1.NBT.6. Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
• 3.OA. 9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. Number Line, by the Math Learning Center is a fantastic FREE app that will help kids visualize number patterns and understand number operations. The app is well-designed with several useful features. The number line can be set by ones, twos, fives, tens, twenty-fives, and hundreds. It can also be customized to show multiples of any whole number from 1 to 100. This feature is perfect for skip counting and/or for visualizing multiplication. The app permits kids to add and manipulate forward & backward jumps – a great feature for teaching addition & subtraction. This feature also helps kids visualize multiplication as repeated addition of the same number and division as repeated subtraction of the same number. Teachers are able to hide or reveal numbers on the number line. This feature can be used to challenge kids to apply what they know in order to figure out the missing number/numbers. Teachers can also use this feature to teach kids how to solve more difficult patterns that are missing several numbers; such as 4, __, __, 16.  Kids can use the drawing tools to show what they know. They can write equations and expressions with the text tool. They can screen shot their work and use it as an exit slip after a lesson. Add this one to your virtual toolkit today – “seeing math” helps kids understand it. 🙂 Free Protractor from Pongo Soft is another tool that you may want to add to your digital toolbox. The angle can be set in two ways: by touching the pointer or by entering the angle on a keypad. Once the angle has been set, it can be locked to avoid movement of the pointer when taking readings. Kids can also use this tool to see how many degrees are in a straight angle and a right angle or to discover the difference between an acute angle and an obtuse angle. They can easily see what combinations of angles are equal to a straight angle.  Since the app is free, there is some advertising across the top. Check out this FREE educational app for your geometry students. FREE educational app – Number Pieces from Math Learning Center. This educational app is the digital version of place value manipulatives, hands-on tools used to help students understand place value. Using the place value models within this app, kids can visualize the process of adding and subtracting ones, tens, and hundreds. The app has a function that permits kids to break apart pieces or join them together. This feature is fabulous for kids who need concrete examples. The app also includes expanding edge pieces which can be used to introduce arrays. Other features of the app include: three colors for identifying groups, drawing tools for labeling, a text tool for writing number sentences, zooming & scrolling for larger numbers. Thanks to the Math Learning Center, teachers & their students have another great app to add to their digital toolkits!

Factor Samurai FREE again for a limited time – Factor Samurai, a fun game to practice multiplication/division while looking for prime factors. The goal of the game is to cut falling numbers down to their prime numbers. So if the number 14 is on the screen, it would be cut once to become 2 and 7. If the number 18 is on the screen, it would be cut twice – first to 3 and 6 and then the 6 would be cut to 2 and 3. The game has three levels – grasshopper, apprentice, and master. The speed of the falling numbers increases in each level. Once a player has cut 3 numbers that are already prime, the game is over. The score (showing how many numbers were cut down to their prime) is displayed! There is an option to play the game through the Game Center. This educational app is fun – a game that helps kids with an important math standard!

Common Core Standards met:

• 4.OA.4 Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors.

8 GREAT Apps for Teaching Fractions

Here are 8 great apps for teaching fractions and the first three on the list are FREE! Currently FREE  – Fractions by Brainingcamp, an excellent educational app for teaching fractions. The app covers 7 topics: introduction to fractions, equivalent fractions, common denominators, comparing/ordering fractions, adding/subtracting fractions, multiplying fractions, and dividing fractions. Each topic includes: a narrated lesson (with visual models), virtual manipulatives for kids to explore, practice questions to check understanding, and a challenging game for additional practice. Kids earn badges as they work through the components of each topic.

WOW – I love everything about this app. The lessons are wonderful. The manipulatives are designed to promote understanding of the concepts presented. The practice questions give students and their teachers a check of their understanding. And, the challenging games helps kids further master the topic. It would be a fabulous for grades 3 and beyond!

Common Core State Standards met:

This FREE app just keeps getting better and better because the developer encourages teacher input. How wonderful is that – a developer willing to listen to teachers’ needs!

Oh No Fractions! is a great FREE iPhone/iPad app for comparing and exploring fractions. The educational app is simple to use – kids just swipe to the right or the left to indicate whether one fraction is “greater than” or “less than” or “equal to” a second fraction. As they work, kids can tap above each fraction to see if it can be reduced/simplified – a great feature. But, one of the best features of this app is the “peek”/”prove it” feature. Kids can use a manipulative to “peek” at an answer before they commit to it or they can use the manipulative to “prove” their answer later. This feature is fabulous because it allows the child to visualize his/her answer. Kids can also use this app to practice finding the common denominator. Then they can use it for addition, subtraction, multiplication, and division of fractions. The app also generates corresponding decimals/percentages for each answer. What a great tool for helping kids to understand fractions!! It’s no wonder that it received the 2013 Children’s Technology Review Editor’s Choice Award.

Currently \$3.99 – Slice Fractions was recently listed as one of Apple’s Best of 2014:Apps. Kids learn about fractions as they slice through ice and lava to clear a path for a cute mammoth. Along the way they collect silly hats for the mammoth to wear. As they solve the app’s 90+ physics puzzles, they are exposed to key concepts of fractions – partitioning, equivalent fraction, numerator/denominator notation, ordering, subtracting from a whole, etc. Kids will enjoy learning about fractions in this wordless environment that seems more like a game than math lessons. I love that the app encourages kids to be problem solvers. Its replay button permits them to try each puzzle again and again until they figure it out. Hints are only given when support is needed. The end result is that kids are learning through discovery! It’s no wonder that this app has received so many accolades: Apple Editor’s Choice, Editor’s Choice for Excellence in Design: Children’s Technology Review, Winner of a Parents’ Choice Gold Award 2014, Gold Medal Winner 2014: International Serious Play Awards, and Best Family Friendly Game 2014: Indie Prize Showcase Awards.

From England and currently \$1.99 –  Squeebles Fractions, an app for the iPhone/iPad that is designed to teach fractions to 7 – 11 year olds. The Squeebles want to enter a cake making contest but their ingredients have been stolen by the Math Monster. By working on the app’s 4 games, kids help the Squeebles earn back their ingredients. In Piece of Cake, kids drag the fractional part of a cake to a Squeebles when he asks for it. The easy mode covers halves, fourths, thirds. The hard mode cover fractions to tenths. In Tricky Pairs, kids have to match pairs of equivalent fractions. In the easy mode they match 4 pairs and in the hard mode they match up to 9 pairs. Think Big has kids feeding cake to the Squeeble that calls out the biggest fraction. The easy mode covers halves, fourths, thirds. The hard mode cover fractions to twelfths. Super Sums requires kids to add fractions as quickly as they can and has three levels of difficulty. After earning ingredients, kids can create cakes and enter them in The Cake Show – fun! Another great thing about this app is that you can have more than one player. My only concern is that the easy mode of Piece of Cake requires kids to know some equivalent fractions – for example, it asked kids to pick 3/4 of a cake divided into 8 pieces, 1/3 of a cake divided into 6 pieces, etc. I wish it would have required a basic knowledge of fractions in the easy mode then moved on to equivalent fractions in the hard mode. This app is cute, fun, and provides great practice for a wide spectrum of kids.

Geoboard by The Math Learning Center (a nonprofit organization dedicated to K – 12 education) is a FREE app that turns your iPhone/iPad into a virtual geoboard. Geoboards can be used as tools to teach mathematical concepts such as polygons, perimeter, area, line segments, angles, congruent shapes, symmetry, fractions, etc. Shapes are created by stretching bands on the geoboard’s pegs. There are 5 colors of bands in the iPhone version and 8 in the iPad version. There is also a tool to fill in shapes. On the iPad version, you can switch from the standard 25 peg board to a 150 peg board to create more complex shapes. This is a great app with the potential to be used in so many ways. FREE for the iPad, Virtual Manipulatives contains math manipulatives for teaching fractions, decimals, and percents. Included are tiles/circles divided into halves, thirds, fourth, fifths, sixths, eighths, tenths, and 12ths AND their corresponding decimals and percentages! The manipulatives are color coded across the settings so that 1/2 is blue as is .50 and 50%. Kids drag tile pieces onto the work area to compare fractions/decimals/percentages. In the settings you can change from tiles to circles, make the pieces transparent, and hide the numbers on the pieces. Completed work can be easily saved to photos. Finding equivalent fractions has never been so slick – WOW!!

Common Core Standards met:

• 3.NF.3 – Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
• 4.NF.1 – Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.  From the National Council of Teachers of Mathematics comes a FREE app called Equivalent Fractions. Kids create equivalent fractions by dividing and shading squares or circles. Circles can be divided into 24ths. Squares can be divided into 144ths. In the play mode, a fraction is shown and kids must create 2 additional fractions that are equivalent. All 3 fractions must have different denominators. The app also places the fractions on a number line – a great visual for comparing! There is also a “build your own” mode which would be fabulous to use for guided exploration & practice. Kids could also use this section as a virtual manipulative when working independently. This app is an excellent resource for the classroom !!

Common Core Standards met:

• 3.NF.3 – Explain equivalence of fractions and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.  Another FREE app is Counting Board HD, a colorful number grid that can be used to help kids learn basic number concepts. The app is advertised as being suitable for 2 to 4 year olds but it can also used with older students. I frequently used number grids with third graders. Number grids help kids see patterns and visualize math concepts. With younger children, the app can be used for counting to 100 – by ones, fives, tens. Younger kids can also learn basic addition and subtraction by using the app to count up or count back. With older kids, number grids can be used to teach: greater than and less than, how to find missing addends, place value concepts, skip counting, and more! The app can be used with the numbers showing or hidden and the pronunciation can be on or off. The app simple to use, visually appealing, and useful for so many math lessons. I love this app! It’s so much easier than dragging out the laminated number grids and counters. 🙂

Common Core Standards met:

• K.CC.1. Count to 100 by ones and by tens.
• K.CC.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
• 1.NBT.5. Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
• 1.NBT.6. Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
• 3.OA. 9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. Number Line, by the Math Learning Center is a fantastic FREE app that will help kids visualize number patterns and understand number operations. The app is well-designed with several useful features. The number line can be set by ones, twos, fives, tens, twenty-fives, and hundreds. It can also be customized to show multiples of any whole number from 1 to 100. This feature is perfect for skip counting and/or for visualizing multiplication. The app permits kids to add and manipulate forward & backward jumps – a great feature for teaching addition & subtraction. This feature also helps kids visualize multiplication as repeated addition of the same number and division as repeated subtraction of the same number. Teachers are able to hide or reveal numbers on the number line. This feature can be used to challenge kids to apply what they know in order to figure out the missing number/numbers. Teachers can also use this feature to teach kids how to solve more difficult patterns that are missing several numbers; such as 4, __, __, 16.  Kids can use the drawing tools to show what they know. They can write equations and expressions with the text tool. They can screen shot their work and use it as an exit slip after a lesson. Add this one to your virtual toolkit today – “seeing math” helps kids understand it. 🙂 Free Protractor from Pongo Soft is another tool that you may want to add to your digital toolbox. The angle can be set in two ways: by touching the pointer or by entering the angle on a keypad. Once the angle has been set, it can be locked to avoid movement of the pointer when taking readings. Kids can also use this tool to see how many degrees are in a straight angle and a right angle or to discover the difference between an acute angle and an obtuse angle. They can easily see what combinations of angles are equal to a straight angle.  Since the app is free, there is some advertising across the top. Check out this FREE educational app for your geometry students. FREE educational app – Number Pieces from Math Learning Center. This educational app is the digital version of place value manipulatives, hands-on tools used to help students understand place value. Using the place value models within this app, kids can visualize the process of adding and subtracting ones, tens, and hundreds. The app has a function that permits kids to break apart pieces or join them together. This feature is fabulous for kids who need concrete examples. The app also includes expanding edge pieces which can be used to introduce arrays. Other features of the app include: three colors for identifying groups, drawing tools for labeling, a text tool for writing number sentences, zooming & scrolling for larger numbers. Thanks to the Math Learning Center, teachers & their students have another great app to add to their digital toolkits!

Common Core Standards:

• 1.NBT.6. Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
• 2.NBT.1 Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases: a. 100 can be thought of as a bundle of ten tens — called a “hundred.” b. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
