Worksheet Overview

In this activity, we will be multiplying a two-digit number by a one-digit number.


To do this, we need to partition the two-digit number into its place value. 


So, let's try multiplying 22 by 7


The first step is to partition 22.

22 can be partitioned into 20 and 2.


The next step is to multiply the ones and tens by 7.

2 × 7 = 14

20 × 7 = 140


The final step is to add the products together.

140 + 14 = 154


So, 22 × 7 = 154


Let's try an example question together. 



Work out the missing number:  

23 × 4 =         



We are trying to work out 23 lots of 4.

23 can be partitioned into 20 and 3.


So we work out 20 lots of 4 and then 3 lots of 4.

20 × 4 =  80 

3 × 4 =  12 


Now add the products together.  

80 + 12 =  92


So, 23 × 4 =  92


Now you've seen the method to use, it's your turn to try some questions.
