The pairs of cubes looked like this:
The children then got into four groups according to their pair of cubes.
Can you explain what these pairs of cubes stand for?
Mrs Bunting showed them a way of recording the way they had
into different groups, called a tree diagram.
sorted themselves
At the bottom were all the pairs of cubes. Then they divided into two branches. The
red cubes went to the left and the green cubes went to the right.
Then they divided into whether they had black cubes or yellow cubes. Now there
were four branches
Here is the tree diagram:
