Children practice forming their numbers using 4 100g / 350g tubs of blue blueberry, red cherry, lemon yellow, and orange scented modeling dough, a 15 x 10 inch (38.1 x 25.4 cm) wipeable play mat numbered 1 - 10, and nature-themed counting cards that encourage children to count out loud as they fill the dots with dough! Easy as 1, 2, 3!
