**Unit 2: Multiplication and Division **

In this unit, the students are engaged in activities and lessons that aim to develop a deep understanding of the concepts involved in multiplication and division. Through hands-on investigation and word problems, the mathematicians will practice noticing the situations that are associated with multiplication and division and recognizing the actions of these operations.

Key ideas:

*understanding the concepts of multiplication and division

*using concrete objects and drawings to represent multiplication and division problem situations

*creating and interpreting equations to represent multiplication and division problems

*understanding the relationship between multiplication and division

In third grade, students explore multiplication as a way to determine the total quantity when there are groups that contain an equal number of objects. This total can also be found through repeated addition.

There are 2 types of division that third grade students work to visualize. The first is when we know how many objects are in each group and need to find out how many groups there are. The second is is when we know how many groups there are, but not how many in each group. Division can also be accomplished through repeated subtraction.

The mathematicians will use set models (equal groups), arrays (rows and columns) and number lines to visuals and depict multiplication and division situations.

This unit also explores the properties of multiplication and division and begins to build fact fluency, but not through pure memorization of facts.

Students need to make connections in their learning in order to strengthen their understanding of concepts. Patterns are an important part of of this as well as building onto previous knowledge of addition and subtraction.

Learning Goals for Students (I Can Statements)

* I can create models to show multiplication and division.

*I can build multiplication and division equations and tell what each number in the equation represents.

*I can use multiplication and division to solve problems.

*I can explain how multiplication and division are related.
