Multiplication 3rd Grade Review

Multiplication is a way to add a number to itself a certain number of times. For example, 3 multiplied by 4 means adding 3 four times (3 + 3 + 3 + 3).

10 x 7 = 70

Multiply the number of rows by the number of students per row: 10 x 5 = 50.

3 x 6 = 18

4 x 5 = $20

A factor is a number that is multiplied by another number. For example, in 3 x 4, both 3 and 4 are factors.

The result is the same number. For example, 5 x 1 = 5.

The result is always 0. For example, 7 x 0 = 0.

An array is a way to organize objects in rows and columns to help visualize multiplication. For example, 3 rows of 4 objects each represent 3 x 4.

You can check by using addition. For example, if you calculated 3 x 4 = 12, you can add 4 three times: 4 + 4 + 4 = 12.
