About this item:
Simple addition is a snap—with hands-on boards and counters children love to use! Kids simply grab a preprinted board featuring an addition problem through 10, attach the corresponding number of counters to match each addend...then count the counters to find the sum. You get 20 durable plastic equation boards, 60 plastic counters in 2 colors and an activity guide; boards measure 1 5/8" x 5 1/2".
