Mason has 33 building blocks. Hannah has 37 building blocks. Pick a way to model how many blocks Mason has. Pick a way to model how many blocks Hannah has.
The question tells us that Mason has 33 blocks. Mason has placed his blocks in a long line. He made his line using three lots of 10 and three more. Three lots of 10 is 30, and three more makes 33. We have to pick one of these models. We have to pick the one which shows 33 blocks. Both of these models have three tens. Three tens are 30, 10, 20, 30. The first model has five ones. The second model has three. 33 is three tens and three ones. So, this is the model which shows Mason’s 33 building blocks.
We know that Hannah has 37 building blocks, so we’re looking for the model which shows three tens and seven ones. Both of these models have 30, or three tens. The first model has five ones, and the second model has seven. 37 is three tens and seven ones. So, this is the model which shows how many building blocks Hannah has. Three tens and seven ones makes 37.
