## Concept Mats and Arrays

### Model Multiplication

Before beginning the lesson, spend some time building each of the Lesson 1 focus facts. The Concept Mats and Arrays below can be printed and reused with each lesson. Using simple manipulatives (goldfish crackers, M&M’s, and pennies), students can create both models and arrays to illustrate each fact. This activity can be done whole-group or as a Multiplication center.

### Connect to Division

Use the Concept Mats to build the Division counterparts! Give students the total number first and tell them how many groups to divide them into. Ask, “How many objects are in each group?”[spacer]
