Math practice meets tactile exploration—with colorful match-ups students can’t wait to get their hands on! Children just select an activity card showing place value blocks or a place value chart…touch and count the textured dots to identify the two- or three-digit number…then find the matching number card to show their answer! You get 40 self-checking match-ups divided into 4 color-coded pockets, plus a guide. Pockets measure 4" x 9 3/4".
