A short sorting task on factor pairs for Year 4 maths. Pupils compare the factors of 24 and 36, writing each lettered number from the bank into the right region of a Venn diagram, so shared factors like 1, 3, 4 and 12 land in the overlap. The answer key shows the finished diagram. Supports the England National Curriculum objective on factor pairs and commutativity.
Number - multiplication and division
“Recognise and use factor pairs and commutativity in mental calculations”
Finding which numbers divide 24 and 36 is factor pair work in disguise.
Pupils write each letter into the correct region of the diagram.
Nine lettered numbers to place, including 8, 12, 18 and 36.
Two overlapping circles labelled Factors of 24 and Factors of 36.
The completed sort, region by region.
Lesson starter
A ten-minute opener before teaching factors or common multiples.
Paired task
Two pupils can argue each number into its region together.
Early finishers
Short enough to hand out as a standalone extra.
