Our self-checking apples introduce counting and quantities—with numbers 1-10 on one side and 11-20 on the other! Kids simply count the seeds on each apple—then slide out the worm to check their answer. Plus, the durable plastic apples are perfectly sized for little hands, so they’re great for strengthening fine motor skills! You get 10 double-sided apples; each measures 3" x 3 1⁄2".
