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.

GOAL

3X groups of 5 = 5 groups of 3

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

Concrete: 5 x 23

Using place value blocks for: 5 x 23

5 X 105 X 10 5 x

Pictorial: 5 x 23 Area model: X X X3 15

Connected to Number:5 x 23 5 x 23 23= X5X5X
