We have been exploring different ways we can make numbers.

Regrouping in math is when you make groups of ten when performing operations.

To decompose (break apart) in math is to break down numbers into parts.

We used these strategies to help us solve addition and subtraction equations. 

Conceptual Understandings:
· the operations of addition and subtraction are used to process information to solve problems
· that number operations can be modeled in a variety of ways
