If you are having a party and you want to have lots of sodas, you can use multiplication.

Sodas come in groups of six.

Five groups of six would be 30 sodas.

5 x 6 = 30 sodas

Sometime multiplication can be used when objects are in rows or columns,

or arrays.

Here is an array of flowers.

There are 3 rows of 6 flowers.

3 x 6 = 18 flowers.

How many groups?

How many in each group?

There are 3 groups of 4 balloons.

Multiplication can be used!

3 x 4 = 12 balloons

How many groups?

How many in each group?

Multiplication can be used!

4 x 3 = 12 tires
