Math: How Many Packages? How Many Groups?

Last week we began our work in Unit 8 about multiplication and division. We will work to have many strategies to solve these types of problems including arrays, the US algorithm, and the expanded algorithm.Goals of this unit include:

Multiplication with 2-Digit Numbers

Students estimate products and practice strategies for solving multiplication problems with 2-digit factors.

Strategies for Multiplication

Students practice strategies for solving 2-digit by 2-digit multiplication problems. 

Solving Division Problems

Students use representations and story contexts to develop strategies for solving division problems with 1-digit or small 2-digit divisors.
