Hip Hip Array!

We have been exploring arrays!

Row x Column = Product

The multiplication for the array above is
3 x 4 = 12
because it has 3 rows of 4.

When the factors are different digits, 
the arrays are in the shape of a rectangle. 
When the factors are the same digit, 
the array are a square!

We practice making arrays ourselves!
First, we worked with tiles and created arrays like these:

Afterward, we looked for 
 materials in our classroom that we could 
use to create some more arrays! 

Check these out!

2 rows of 2 atlases

3 rows of 6 pieces of clay

2 rows of 5 clocks

4 rows of 4 pieces of clay

4 rows of 4 balls of clay
4 rows of 4 pieces of clay

 Did you notice the the 4 x 4 square array was very popular?

4 rows of 3 clay birds

4 rows of 5 connecting cubes

3 rows of 6 glue bottles

6 rows of 6 dice

4 rows of 3 dictionaries

2 rows of 3 pencil sharpeners

3 rows of 3 clocks

3 rows of 2 thesauruses


Here is a quiz about arrays!
Rows   x   Columns on PhotoPeach

Which array is your favorite?

Do you know more factors that will make square arrays?

Do you see any arrays in your home?

Tell us about it in your comments!


  1. Dear Mrs. Ranney and Class,

    My favorite array is the thesaures. It is very cool! I know what will make a square array: T.Vs! 10 rows of 10 = 100! In my room the lights that make a square array. 2 rows of 2 = 4!
