Let’s have a look at these windows. They are organised into arrays. We can count in 2’s to find out how many windows there are altogether.

Our repeated addition number sentence is   2+2+2+2+2=10

Have a go at writing a repeated addition number sentences for the windows in these Victorian houses.

Activity 2

Today we are going to introduce multiplication. The sign for multiply is an X

When we multiply, we talk about groups of, or lots of.

This array has 4 columns of 2, or 4 lots of 2.

Our multiplication number sentence is 4x2=8

Have a go at writing multiplication number sentences for the arrays below. Remember to circle the groups of 2 before you write your multiplication number sentence.

Activity 3

Next we are going to look at coins to count how much money we have altogether. Let’s recap the value of these coins.

We can count up in groups to work out how many pence there are altogether.

This purse has some 2p coins in. We can count up in 2’s to find out how many pence there are altogether.

To write our multiplication number sentence we need to find out how many groups we have. There are 3 coins so we have 3 groups of 2. When we write our number sentence, we can write 3x2=6.

Have a go at writing multiplication number sentences for the purses below.

Activity 4

Here is a menu for Queen Victoria’s afternoon tea. This menu is for only 1 person? Can you work out how many food items will be needed for 2 guests? How about 5 or 10 guests? You could try counting in 2’s, 5’s or 10’s to work it out.
