In cycle one we focus on ones, tens and hundreds units. The students are practicing identifying what each digit represents in a number (397 = 3 hundreds, 9 tens and 7 ones) and representing numbers with base ten blocks.
We have been learning numerous strategies to help with addition. The students are taught each strategy and practice using each. When they are doing addition problems on their own they can choose the strategy they are most comfortable with. Some of the strategies we covered are: using a number line, counting on with your fingers, using tokens to add and making groups of ten.
Below are some games to reinforce these concepts and help children continue to practice their learning at home:
