Description: This app collects no data, is free, and has no ads. This app is for kids learning addition in an entirely new visual way, where they create many pairs of numbers that add to the same sum. It is also for parents and teachers who want a fun visual way on a number wheel to explore addition patterns with kids and see a big picture of number patterns.

This is much more than another cute way to drill addition facts and subtraction. Kids are learning fundamentals, they are playing with, and learning place value and that our numbers are ten based, that this helps see addition and subtraction patterns. When they learn addition on a number wheel with this app, subtraction is easy: They have been earning badges and learning set of numbers that add up to the same number. To do subtraction, choose the badge of the number they want to start with. Touch 0/10 (the right choice will be visible) and that number (for a teen number like 15, choose 10 and 5). They create a vertical line. ALL numbers to subtract will also have the answer above or below it. They are reversing addition. They are also set up to learn multiplication, division, fractions, squares, and more on number wheels.

Addition pairs that add up to the same number create parallel lines on a number wheel. Kids love starting with any two numbers (one-digit) and then taking away one from the smaller number and adding it to the bigger number. ZERO is the HERO. When you reach 0 (example 4+3, then 5+2, then 6+1, then 7+0, fireworks happen because the line from 0 points to the answer of 7 for ALL the pairs kids have created to get to 0. If the larger number reaches 10, then the answer is also obvious (8+7, then 9+6, then 10+5 equals 15).

Kids earn badges by finding all the pairs on the wheel that add up to a number. They are learning sets in a pattern and can have fun earning each badge 1-20 as many times as they like.

Basically, if you choose any two numbers on the wheel to add, you will create a line. When you touch the number one bigger than the bigger number, and one smaller than the smaller number, you get another line, a railroad track line (parallel) that adds up to the same number. You added one and took away one, so it has to add to the same number. It can be great fun to do this with pennies (or watch the youtube video) to help kids get how this works.

CAN WORK WITH MULTIPLE NUMBERS AND MULTIPLE DIGIT NUMBERS: When students are proficient with the app, they can add 2 numbers, then add a third to that, then a fourth number. They can keep track of tens with fingers or marks on paper. They can also do it with 2 or 3 digit numbers. First add the Ones, Add the tens (carry over helps students learn place value), Then add the hundreds (ten tens).

The number wheel is a 10 base number system, mirroring our number system. So the structure is the same. This allows natural patterns in the ones digits to show up, which hold true, no matter how big the number. Think of a water meter or a bike mileage gauge that has 0-9 number wheels for 1s, 10s, 100s, and 1000s.

0 + 10 = 10, then one less than 10 is 9. And one more than 0 is 1, and you have horizontal line.
If you work your way down, you'll see that 8+2, 7+3, and 6+4 are all horizontal lines. The line helps kids see the patterns, which are really important in addition and subtraction.

So kids can actually see the patterns in numbers showing up in sets of numbers. They are learning the basic pattern of numbers, learning it because this approach is so visual and shows the patterns.
