Teaching 3.OA.A.2 – Interpret Whole-Number Quotients of Whole Numbers

 

divisionOperations & Algebraic Thinking – 3rd Grade

Represent and solve problems involving multiplication and division.

CCSS.Math.Content.3.OA.A.2
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.
