Lesson 2:
Division as an Unknown Factor Problem
Learning Objectives:
- I can interpret whole number quotients of whole numbers (for example, understanding 56 ÷ 8 as the number of objects in each share when 56 objects are divided into equal shares of eight objects each). (3.OA.A.2)
- I can apply properties of operations as strategies to multiply and divide (for example, commutative, associative, distributive*). (3.OA.B.5)
