Quickly build a hundred chart--then easily add on to teach up to 120! Our large quadrant pieces go up in a snap, so you can spend your time teaching instead of assembling. Bold and easy to see from all over the room! Includes 20 number frames, 20 cover-up squares, and a unique t-shaped more/less piece that builds mental math fluency. 24" x 34"H when assembled. Grades K and up.
