Students have been practicing using multiple strategies to add and subtract multi-digit numbers. Today, students played “subtraction target practice.” The game is played in pairs and starts at 20. The first player flips two cards (0 -9), and using a counter as decimal, makes a number out of the two cards. For example, flipping 2 and 6, the student could make 6.2 or 2.6. Whichever they make, they subtract from 20. Their partner then flips 2 cards and makes a number, and subtracts it from the previous number. The player to get closes to 0 without going under 0 wins.
