This week we're learning about Perimeter. Perimeter is the space around something. These are some things that we are measuring: notebooks, math books, the classroom walls. We measured square tiles on paper.
Last week we learned about compatible numbers Compatible numbers are numbers that are easy to add and so you don’t have to regroup. Some examples are.599 +499. It’s easier to add 500+600.
