Find out what a "fault-free" rectangle is and try to make some of your own.

Use the fraction wall to compare the size of these fractions - you'll be amazed how it helps!

Using the picture of the fraction wall, can you find equivalent fractions?

Can you find all the different ways of lining up these Cuisenaire rods?

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?

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

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