This is a mat that you can use in a sheet protector, laminated, or simply printed to teach the concept of addition and subtraction. This can be used with addition and subtraction flash cards, or alone with whatever numbers you or the student wish to use. This works with word sentences as well.
You can use beads, cheerios, bears, or even paper punched into shapes for the counters!
In the addition mat, put the amount of counters in each box, then drag them down to the "equals" box.
In the subtraction mat, put the larger number of counters on top, then drag the "minus" number to the X box, ant the remainder to the "equals" box.
