1. How many of your students come to you with a good understanding of multiplication? Research shows that you should develop student understanding PRIOR TO teaching students an algorithm.

2. GOAL

3. 3X5 5+5+5 3+3+3+3+3 3 groups of 5 = 5 groups of 3

4. 5 x 23 Concrete: Build with tiles, use place value blocks Pictorial: Draw a representation  Use this to show how to use the distributive property to solve this problem Number: What does this strategy look like in number Algorithm

5. Concrete: 5 x 23

6. Using place value blocks for: 5 x 23

7. 5 X 105 X 10 5 x 3 5050 15

8. Pictorial: 5 x 23 Area model: 10103 5 10 X5 50 10 X5 50 5 X3 15

9. Connected to Number:5 x 23 5 x 23 23= 10+10+3 10 10 3 X5X5X5 5050 15

10. Partial Products

11. Let’s Reflect Jot down important ideas/strategies you want to remember about teaching multiplication.
