Find 3 x 7

2 x 7 = __

1 x 7 = __

__ + __ = 

So, 3 x 7 = __

2 x 7 = 14

1 x 7 = 7

14 + 7 = 

So, 3 x 7 = 21

You can find 7 x 9 by breaking a large array into two smaller arrays. Use smaller arrays for multiplication facts that you know, such as 2s facts, 5s facts, or doubles facts. Use two smaller arrays to find 7 x 9. 

5 x 9 = 45

2 x 9 = 18

45 + 18 = 63

So, 7x9 = 63

To solve a multiplication equation that has 8 as a factor, you can break it into two or more facts. You can use a 4s fact and double it to find the product. Split the 8 x 7 array into two equal groups. 

4 x 7 = 28

4 x 7 = 28

28 + 28 = 56

So,  8 x 7 = 56

Rafael broke up an array for 6 x 3 into two new arrays. Both of his new arrays are the same. What were the two arrays?

Two 3 x 3 arrays

4 x 8 = (2 x 8) + (2 x 8)

4 x 8 = 16 + 16

4 x 8 = 32

There are 32 books on the shelves

Break the array into two smaller arrays using a doubles fact and solve 6x8.

3 x 8 = 24

3 x 8 = 24

24 + 24 = 48

So, 6 x 8 = 48

8 x 9 = (2 x 9) + (2 x 9) + (2 x 9) + (2 x 9)

8 x 9 = 18 + 18 + 18 + 18

8 x 9 = 72
