Have fun and improve gross motor skills at the same time with this 1.8m x 2.1m PVC Number Mat. The mat can be folded so that any set of 10 numbers from 1 to 30 are shown. At a basic level use the mat to help children count by walking up the mat from one. Later, students can do addition equations by walking up the mat from one number to another or subtract by walking in the opposite direction. The thick material is suitable for both inside and outside use. Handy reinforced holes in each corner means it can be attached to the wall for display purposes between uses.
