Great learning fun - This is a wonderful addition to any sand/play yard that incorporated sorting/matching/counting into fun and interesting self-contained play time. The worms are different sizes, lending themselves to many different learning activities, as well as many different imaginative games. Amazingly, the boys AND the girls love these critters, the bright colors keep them from being too gross for the little girls. Great for counting skills for preschools, color identification for the younger groups, and fractions for the elementary ages. Limitless uses. Washable, durable, hours of fun. Everytime you take them out, they can be used for something different, either adult or child directed play time. Great purchase.
