Learn about grouping numbers equally.
This lesson includes:
- one catch-up quiz
- one video
- two activities
To get started, let's see how well you know this topic already. Take the catch-up quiz below to find out.
Begin by watching the video.
It shows how we can put objects into equal groups of twos, fours, fives and tens, focusing on the term 'into groups of' (for example 20 'into groups' of 10).
After looking at the importance of making equal groups rather than unequal groups, the video features opportunities to handle real objects and answer questions on grouping equally.
This lesson follows on from division with sharing to look at division with grouping. Ultimately, this will help you make the connection between multiplication (groups of) and division (putting into groups).
Instead of working out how many items are in each group, you are now looking at finding how many groups there are when a known quantity is divided into equal groups.
This is a subtle but important difference to understand when you’re sharing a quantity.
It is also helpful to know that knowing one grouping fact can help you work out the related one.
For example, 20 into groups of 2 is 10, can help you work out 20 into groups of 10 is 2.
Have a go at this worksheet about making equal groups. You can print it out or just make a note of your answers on a sheet of paper.
Explore this interactive activity. There are lots of different ways for you to understand grouping and sharing.
