Race To 200-Race to Zero

This week, we continued to focus on composing and decomposing three digit numbers using base ten blocks. The children are discovering when to trade/compose 10 ones into a ten and 10 tens into a hundred. Also, when subtracting, they are trading a hundred for 10 tens or a ten for 10 ones. Also,we continue to use a variety of strategies to solve 2 step word problems.
