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.
 

Rod Fractions 
Age 7 to 14
Challenge Level Yellow star

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?

Colour Building 
Age 11 to 14
Challenge Level Yellow star

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

Searching for Mean(ing) 
Age 11 to 16
Challenge Level Yellow starYellow star

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?

Combining Lengths 
Age 11 to 16
Challenge Level Yellow star

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

Different by One 
Age 14 to 16
Challenge Level Yellow star

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

Cuisenaire Environment 
Age 5 to 16
Challenge Level Yellow star

An environment which simulates working with Cuisenaire rods.

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

NRICH is part of the family of activities in the Millennium Mathematics Project.
