In this game students will practice three digit subtraction. There are four choices of cards- Color with and without QR codes or black and white with and without QR codes! Students take turns picking a card, solving, checking their work and then moving on the game board. This includes a game board, student and teacher directions as well as the four types of subtraction cards. (Please note, it is four designs, not four sets! They all use the same subtraction sentences.) Students have 40 cards to play with.
