# Visualising with Cuisenaire

### Visualising with Cuisenaire

Although some teachers associate their use more with primary classrooms, Cuisenaire rods can be a powerful visualisation tool to help students of all ages solve problems about fractions, ratio and proportions. In this feature, we introduce our new Cuisenaire interactive environment with tasks designed to promote visualising and strategic thinking.

The last date for students to submit solutions is Monday 3 February.

##### 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.
