Math practice meets tactile exploration—with super-cute match-ups children can’t wait to get their hands on! Kids just select a textured picture card and touch each animal as they count to 20, add within 20 or compare numbers to 10…then find the matching number or symbol to show their answer! You get all 3 sets, each with 40 self-checking match-ups in 4 leveled pockets, plus an activity guide; pockets measure 4" x 9 3/4". Each set also available separately.
