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.
problem
Rod Fractions
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?

Searching for mean(ing)
Age
11 to 16
