In this unit, students will begin to gain an understanding of multiplication by building on 2nd grade knowledge of and practice with repeated addition and arrays. They will learn the importance of seeing a group of items as a single unit and that a group contains a given number of objects. Students will connect the operations of multiplication and division.
Unitataglance
Key concept: Products of whole numbers can be interpreted as a number of groups of a number of objects. 
Key concept: Quotients of whole numbers can be interpreted as either a number of shares (partitive or distribution division) or a number of groups (quotative or measurement division). 
Key concept: We can use drawings and equations to represent and solve multiplication and division situational problems involving equal groups and arrays. 
Key concept: We can use strategies such as the relationship between multiplication and division or properties of operations to multiply and divide.
