Challenge Level

Using only the red and white rods, how many different ways are there to make up the other colours of rod?

These upper primary activities offer opportunities for children to recognise, extend and explain number patterns.

This article for primary teachers outlines how we can encourage children to create, identify, extend and explain number patterns and why being able to do so is useful.

Challenge Level

Watch this animation. What do you notice? What happens when you try more or fewer cubes in a bundle?

Challenge Level

Complete these two jigsaws then put one on top of the other. What happens when you add the 'touching' numbers? What happens when you change the position of the jigsaws?

Challenge Level

In each of the pictures the invitation is for you to: Count what you see. Identify how you think the pattern would continue.

Challenge Level

Can you design a new shape for the twenty-eight squares and arrange the numbers in a logical way? What patterns do you notice?

Challenge Level

Investigate the totals you get when adding numbers on the diagonal of this pattern in threes.

Challenge Level

"Tell me the next two numbers in each of these seven minor spells", chanted the Mathemagician, "And the great spell will crumble away!" Can you help Anna and David break the spell?

Challenge Level

This challenge asks you to investigate the total number of cards that would be sent if four children send one to all three others. How many would be sent if there were five children? Six?

Challenge Level

There are ten children in Becky's group. Can you find a set of numbers for each of them? Are there any other sets?

Challenge Level

Challenge Level

Investigate these hexagons drawn from different sized equilateral triangles.

Challenge Level

How many different sets of numbers with at least four members can you find in the numbers in this box?

Challenge Level

Benâ€™s class were cutting up number tracks. First they cut them into twos and added up the numbers on each piece. What patterns could they see?

Challenge Level

This activity asks you to collect information about the birds you see in the garden. Are there patterns in the data or do the birds seem to visit randomly?
