What’s an array?

Here is an array

This array has blocks in a pattern of rows and columns so that it is to see how many there are altogether.

​

There are 4 rows.

​

There are 5 blocks in each row, so there are 5 columns.

​

We can write equations for this array:

​

5 + 5 + 5 + 5 = 20

​

4 x 5 = 20

​

What does this array tell us?

How many rows?

​

How many blocks in each row?

​

So, how many columns?
