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. And… it’s so much easier than dragging out laminated number grids and counters. I love this app! 🙂
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.
