### Teaching Multiplication

## What practice standard could I address?

MP 8 - Repeated Reasoning and MP 7 - Structure

Students could look at the structure of the multiplication table. Instead of teaching 4s and later teaching 8s, I could teach 8s using the 4s.

1x4 = 4 1 x 8 = 8

2 x 4 = 8 2x8 = 16

3 x 4 = 12 3 x 8 = 24

4 x 4 = 16 4 x 8 = 32

5 x 4 = 20 5 x 8 = 40

Do you notice a pattern between the multiples of 4 and the multiples of 8?

Based on this pattern,

7 x 4 = 28 7 x 8 = ? Why?

Why might this be?

8 = 4 x 2

So 5 x 8 = 5 x 4 x 2 = 20 x 2

## Number Talks

Number talks might be a way to help students recognize patterns and the structure of the number which will help them when they are trying to learn multiplication this way. It also help promote listening and speaking skills in the math classroom. Check out some examples of Number Talks below.
