Arrays, Multiples and Factors

Our next math unit covered arrays, multiples and factors.

 Students learned to list the first X number of multiples of a given number.

Examples:

 List the first 6 multiples of 7.

7, 14, 21, 28, 35, 42

List the first 9 multiples of 4

4, 8, 12, 16, 20, 24, 28, 32, 36

Students learned that factors are numbers that can be multiplied to find a given product. Students factored numbers in the form of multiplication problems and listed the factors of the given number.

Examples:

Find all factors of 36.

(1x36), (2x18), (3x12), (4x9), (6x6)

1, 2, 3, 4, 6, 9, 12, 18, 36

Once students learned to factor numbers, we were able to turn those factors into multiplicative arrays to represent a number.

Examples:

We played games with dot cubes to create our own arrays on graph paper.

We created Cookie Tray Arrays.

Lastly,

We made larger-scale arrays on graph paper.
