1. This is the side of a rectangle with 16 blocks total
This is the side of a rectangle with 16 blocks total. There is a height of 4
4x?=16
How can you solve this problem?

2. This is the other side of the rectangle.
If you divide 16 into groups of 4 you will have 4 groups.

3. This is the side of a rectangle with 21 blocks total
This is the side of a rectangle with 21 blocks total. There is a height of 3.
Can you write a multiplication sentence for this?
How can you solve this problem?

4. This is the other side of the rectangle.
If you divide 21 into groups of 3 you will have 7 groups.
21/3=7
3x7=21

5. This is a division problem with 3 groups, there are 4 blocks in each group how
much in all?
The division sentence for this is ?/3=4
How can you solve this problem?

6. Here is there other side of the model. There are 12 blocks in total.
If you multiply 3 x 4 you will 12 in all.
3x4=12
12/3=4

7. This is a division problem with 4 groups, there are 6 blocks in each group how
much in all?
The division sentence for this is ?/4=6
How can you solve this problem?

8. Here is there other side of the model. There are 24 blocks in total.
If you multiply 6 x 4 you will 24 in all.
6x4=24
24/4=6
