2. Standard: “CCSS.MATH.CONTENT.3.OA.A.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.”
3. Pre-Assessment
3.1. Basic mastery moves student to an activity that reviews this mastery.
3.2. Low achieving move to a learning activity that will help build background knowledge.
3.2.1. Reteaching on arrays
3.2.2. Reteaching on inverse operations
3.2.3. Reteaching on fact families
3.2.4. Reteaching on equal groups.
4. Lesson 1: CUBES
4.1. Presentation and interactive media on the parts of CUBES
