The activities in this feature all make use of Cuisenaire rods, which are blocks coloured according to their length. We hope you enjoy being playful with the rods as they help you uncover and connect some important mathematical ideas. Don't worry if you haven't got any rods of your own as you could use our interactive Cuisenaire environment.

problem
Cuisenaire counting
Here are some rods that are different colours. How could I make a yellow rod using white and red rods?

problem
Same length trains
How many trains can you make which are the same length as Matt's and Katie's, using rods that are identical?


problem
Rod fractions
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?



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

problem
Rod ratios
Use the Cuisenaire rods environment to investigate ratio. Can you find pairs of rods in the ratio 3:2?
