Developing children's number sense is key to their success as young mathematicians. In this feature for Primary teachers, we bring together tasks which encourage learners to play with factors and multiples in particular. This exploration will help build children'sĀ 'feel' for numbers as they gain a deeper understanding of the properties of numbers, and the relationships between them.

You can watch a recording of the webinar in which we discussedĀ the mathematical thinking which can be prompted by these problems.

Age 5 to 11

This article for primary teachers outlines why developing an intuitive 'feel' for numbers matters, and how our activities focusing on factors and multiples can help.

Age 3 to 5

In this activity, the book 'The Doorbell Rang' by Pat Hutchins provides an engaging context in which children can explore sharing.

Challenge Level

How would you create the largest possible two-digit even number from the digit I've given you and one of your choice?

Age 5 to 7

Challenge Level

How will you work out which numbers have been used to create this multiplication square?

Age 5 to 7

Challenge Level

Investigate which numbers make these lights come on. What is the smallest number you can find that lights up all the lights?

Age 5 to 11

Challenge Level

Watch the video of this game being played. Can you work out the rules? Which dice totals are good to get, and why?

Age 7 to 11

Challenge Level

Each light in this interactivity turns on according to a rule. What happens when you enter different numbers? Can you find the smallest number that lights up all four lights?
