These squares have been made from Cuisenaire rods. Can you describe the pattern? What would the next square look like?

Here are some rods that are different colours. How could I make a dark green rod using yellow and white rods?

Can you make arrange Cuisenaire rods so that they make a 'spiral' with right angles at the corners?

Can you find all the different ways of lining up these Cuisenaire rods?

Train game for an adult and child. Who will be the first to make the train?

Here are some challenges that you can work on and then see if you can convince someone that your solutions are right! Have a go!

General-purpose interactives for use in primary schools

Try these interactives to improve your skills in a variety of topics.

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

In these activities, you can practise your skills with adding and taking away. You can also solve problems about what happens when we add or take away different numbers!

You and your friends are probably quite good at imagining things and seeing things in lots of different ways. Here you'll put that to use in doing some maths challenges.

Use the Cuisenaire rods environment to investigate ratio. Can you find pairs of rods in the ratio 3:2? How about 9:6?

By following through the threads of algebraic thinking discussed in this article, we can ensure that children's mathematical experiences follow a continuous progression.

This article develops the idea of 'ten-ness' as an important element of place value.

In this article we outline how cubes can support children in working mathematically and draw attention to tasks which exemplify this.

This article for primary teachers expands on the key ideas which underpin early number sense and place value, and suggests activities to support learners as they get to grips with these ideas.
