Hands-On Regrouping Kit- Addition

CHOKING HAZARD (1). Not for under 3 yrs.* Students master addition & subtraction skills...with fun-to-use regrouping kits that make complicated math problems easy to solve! Each kit includes a regrouping tray with 75 place value tiles representing ones, tens & hundreds, plus 40 self-checking problem cards that feature 2- and 3-digit numbers. Students simply place a problem card onto the tray, count out place value tiles to visually represent each number in the equation - then just regroup the tiles to work out the answer. We've even included a handy write & wipe card that lets children record their work. Plastic tray is 8 5/8" x 14 1/4".
