Color-coded according to place value, the 1" foam disks allow students to visually track what happens when they regroup numbers in both addition and subtraction. And they help illustrate that multiplication is the same as repeated addition and division is the same as repeated subtraction. Resealable poly bag plus instruction sheet included.
