12 Fun Apps for Learning Math Facts

April 12, 2015 | appydazeblog

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 appydazeblog | educational apps for kids and the adults in their lives to find out 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!

Common Core Standards met:

3.OA.7 – By the end of Grade 3, know from memory all products of two one-digit numbers.
3.NTB.3 – Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.

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. 🙂

Common Core Standards met:

1.OA.6 – Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
2.OA.2 – Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

$operation math$

Was FREE for a limited time, currently $2.99 – Operation Math, a great educational app from Spinlight Studio. Kids will have fun practicing basic addition, subtraction, multiplication, & division tables in this interactive “spy” game. 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! No wonderOperation Math was given a 2012 Parents’ Choice Award. Get it today – kids will LOVE it!

$Math Mathews$

Was FREE for a limited time, currently $2.99 – Multiplications with Math Matthews, a great new app for studying multiplication facts. Kids join Math Mathews and his crew on a high seas adventure to find treasure and break the curse that turned him into an octopus. There are so many great things about this app that make it perfect for the classroom. The app includes a diary (ship’s log) that gives the back story to this adventure that kids are about to join. I envision teachers using this narrative as a group activity to get kids excited about joining the crew. Then the app is divided into 3 mini-games with each game using a different method of practice. Kids earn badges and collect gold as they practice facts. The app allows you to set which facts it will review. This feature makes this game particularly valuable in the classroom. Teachers can start with ones & twos, add fives, then three & fours – adapting their students’ practice to their teaching. And…the app can be used with 7 different players – perfect for small group practice, centers, etc. It keeps track of the progress for each individual – another plus for teachers. If I was still teaching, I would definitely use this educational app in my third grade classroom – it meet a CCSS for third grade multiplication. What a fabulous & fun learning tool for kids!!

Common Core State Standards met:

3.OA.7 – By the end of Grade 3, know from memory all products of two one-digit numbers.

Download link: https://itunes.apple.com/us/app/multiplications-math-mathews/id611130011?mt=8&uo=4

Was FREE for a limited time, currently $4.99 – Math Racer, an educational app that times how fast kids can answer 10, 20, 50 or 100 problems in 7 different games: addition, subtraction, multiplication, division, add/subtract, multiply/divide, or all operations. I like kids being able to practice related operations together – it makes them pay attention to operational signs & see connections. The app keeps high scores for all areas. It shows which problems were missed and how long it took to answer each question (to the hundredth of a second). Teachers and parents can use this tracking system to document kids’ progress.

This app provides a simple but fun way for kids to practice their facts. I can’t imagine that they won’t love racing the clock to improve their scores. If it is loaded on an iPhone, kids could easily practice their facts in the car on their way to after-school lessons. 🙂

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!

Common Core Standards met:

1.OA.6 – Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
2.OA.2 – Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

Flashcard Ninja

April 7, 2015 | appydazeblog

FREE for a limited time – Flashcard Ninja, an educational app for practicing addition and subtraction with numbers 1 – 20. Kids embark on a journey to become a math ninja. They can record their own sounds to accompany the ninja’s karate moves – a feature that is sure to be a hit. As they answer mixed addition/subtraction questions posed by the ninja master, the “math ninjas” win trophies for their trophy room. A 10, 20, or 30 second timer can be set to allow more time for kids who need it. The timer can also be turned completely off. I wish the app had a setting to customize a child’s practice – addition only, subtraction only, mixed facts up to 10, etc. It would also be nice if the app gathered data. Perhaps the developers will add these options in an update. In the meantime, I can see how this app might appeal to some kids who are otherwise reluctant to practice math. So, check it out while it’s free to see if it works for your children.

7 Math Manipulatives for your Digital Toolkit

March 10, 2015 | appydazeblog

Plan a lesson for Digital Learning Day (March 13) or Pi Day (March 14) with these seven FREE math apps.
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.

$equivalent fractions$

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.

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).

Celebrate Pi Day with 3 FREE Apps (National Council of Teachers of Mathematics)

March 9, 2015 | appydazeblog

$equivalent fractions$ 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.

Pick-a-Path is another FREE math game from the National Council of Teachers of Mathematics. Kids help Okta the octopus reach a target number by choosing the best path from the top maze to the bottom of a maze. There are 7 different levels with 7 puzzles in each level. The puzzles start with basic operations then move to fractions, negative numbers, decimals, and other more difficult skills. Kids have to plan out a strategy to reach the target which can be a specific value, a minimum value, or a maximum value. This app provides a lot of good skills practice. And… as an extra added bonus, kids have to think of a strategy!

$Math concentration$

Math Concentration was developed by the National Council of Teachers of Mathematics for students from preschool through fifth grade. It’s a classic matching game that can be played by one or two players. There are six levels of play – numbers 1- 6, numbers 1 – 10, shapes, multiplication, fractions, and percentages & fractions. In all levels, numbers are represented in different ways – written names, digits, pictures, etc. The game also has two modes – a transparent board (for younger students) or a fully covered board. The game is simple to play and kids earn socks for completing all of the matches on the board. 🙂
