My summer class is already half over and we've just begun to think about teaching multiplication and division. Here's the introductory activity I gave them to think about repeated addition, making arrays, and writing number sentences.
This activity meets the following Common Core Standards for Mathematics.
- 2.OA.4 - Work with equal groups of objects to gain foundations for multiplication. Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
- 3.OA.1 - Represent and solve problems involving multiplication and division. Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.
