Learning to count has never been sweeter! Our ovens give kids hands-on practice with matching numbers to objects, counting objects in arrays and more! Kids just grab a chipboard oven and read the numeral on front…then find the 5 baking sheets with the matching number of treats and slip them inside. When they’re done, they simply open the oven door to take out the sheets and check their answers on back. Set includes 10 ovens and 50 chipboard baking sheets. Ovens measure 3" tall.
