We imagined we had a mummy and daddy rabbit who had a litter of babies.

The children chose how many black and how many white were in the litter.

What is the ratio of black to white?

The two rabbits then have a another litter with the same proportion as the first litter. What could the second litter look like?

Why is this called a proportion?

How is a proportion connected with a ratio?

What strategy could we use to find other possible proportions?

Amongst some strategies shared, one student showed us how we could use a table.

To help us see how that strategy works, this time we had a brown and a white parent rabbits.

We imagined the colour ratio of their first litter.

Then used the table strategy to find possible proportions.

We then created a true proportion and a false proportion of the second litter.

Most of us decided to create a table as strategy for finding that out and we reflected how we thought this was a really useful strategy. We also enjoyed trying to trick our classmates.
