Mouse Paint is a Number Matching Set activity. The paint brushes have the numbers on them and the paint cans have the matching number of dots on them. To make this activity more tangible I hot glued milk jug lids to the bottom of each paint brush so that its raised up. Easier for small hands to pick up. I laminated the paint brushes and used my cricut machine for the letters. The mouse is from clipart images and I always put clear packing tape over the entire foam board for durability. I found the paint cans & brushes with the foam board at the Dollartree.
