Race to a Flat

Use this “race to a flat”  graphic organizer to play a game that helps students understand the base ten value system. They work on exchanging units for rods and rods for flats.

Take turns rolling a pair of dice. Add the dice together to get the sum. Take that number of units from the supply. Place the units in the correct column on your place value mat and make any exchanges possible. Exchanges need to be done before you pass the dice. The first player to get a flat wins!! Have fun.
