What if learning early math concepts could become a fun self-challenge for kids? Ten Frames helps children explore the Base Ten system, as well as simple addition and subtraction. The two trays and 20 counters make these ideas visible and relatable. The two trays hold the counters and strap them together for easy storage. Children practice problem solving, logic, and language skills. Ten Frames is made from all-natural, sustainably-grown rubberwood, and is painted with non-toxic, water-based colors.
