# Operations & Algebraic Thinking – 3rd Grade

**Represent and solve problems involving multiplication and division**.

Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.

*For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8*.

**Teacher Notes**

Making sense of the meaning of division and quotients of whole numbers is critical and lays the foundation for students as they learn more complex mathematical concepts.

**Student Knowledge Goals**

I know what the numbers in a division problem represent.

I know a dividend is the number of objects to be shared equally.

I know a divisor is the number of equal shares or the number in each equal share.

I know a quotient is an answer to a division problem.

I can use common division situations to help them understand the context of a division problem.

I can interpret quotients of whole numbers.
