We have been consolidating our knowledge of Place Value in Grade 2 this term with 3 and 4 digit numbers (and beyond). The children showed a fantastic understanding of reading, ordering and making 3 and 4 digit numbers however when it came to renaming, we noticed they were having some difficulty.
So… I created these number expanders to allow the children to see that numbers can be made in different ways – not only using hundreds, tens and ones. They proved to be a great tool during these sessions as they practised making numbers in a variety of ways.
We then used concrete materials such as MAB or Base 10 blocks and placed them on a Place Value Mat. Students compared their findings with other students in the grade with the same number. It allowed them to physically see the ways that the same number can be made.
