Practise Multiplication Arrays

Look at these pictures:

 

 

Count the rows.

There are 4 rows.

 

Count the number of dogs in each row.

There are 2 dogs in each row.

 

We write this as:   4 × 2

 

To work out the answer, we count all the dogs.

We can count in 2s: 2, 4, 6, 8.

 

There are 8 dogs.

 

4 × 2 = 8

 

 

There are 5 rows.

There are 3 ladybirds in each row.

 

If we count all the ladybirds, we make a total of 15, but there is a quicker way to find out how many there are.

 

We write this as:   5 × 3

We could count in 3s or in 5s. Let's count in 5s because it is easier: 5, 10, 15

 

5 × 3 = 15

So, we know that there are 15 ladybirds in total.
