Add/Subtract

The purpose of the Add/Subtract Floor Mat and Sticker is to offer a kinesthetic opportunity for children to practice one-to-one correspondence (ability to link a number name with one and only one object), odd and even numbers, addition and subtraction, skip counting by any number, counting forward to 100 and backward from 100 and general number sense.

These activities can be used with the Add/Subtract Mat of any size (mini, regular, or large), the Add/Subtract Outdoor Sticker, the 100 Number Grid Classroom Rug, the Add/Subtract 1-120 Mat, and the 1-100 Stencils. Language, images, and videos will show the regular Add/Subtract mat. Adapt activities as needed for your material.
