This week we started a new math unit on Numeration. To help practice our skills with trading and regrouping we played the game "Race To 100". The students play in partners. Each partner takes a turn to roll the die, placing that number of "units" on the place value mat, keep rolling and when you get to 10 "units" you trade them in for a stick of "ten" and so on until you have 10 tens that can be traded in for 1 one hundred. The first player to get to one hundred wins that round.
Here it is in action.
