When working on the activities in this feature, you'll need to be able to visualise what's going on. To help you, we have provided some interactive Cuisenaire Rods that you can use to compare lengths, try out different combinations of rods, and make sense of questions about fractions and ratios.

Age 7 to 14

Challenge Level

Pick two rods of different colours. Given an unlimited supply of rods of each of the two colours, how can we work out what fraction the shorter rod is of the longer one?

Age 11 to 14

Challenge Level

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

Age 11 to 16

Challenge Level

If you have a large supply of 3kg and 8kg weights, how many of each would you need for the average (mean) of the weights to be 6kg?

Age 11 to 16

Challenge Level

How many different lengths is it possible to measure with a set of three rods?

Age 14 to 16

Challenge Level

Can you make lines of Cuisenaire rods that differ by 1?

Age 5 to 16

Challenge Level

An environment which simulates working with Cuisenaire rods.
