Turning

Stage: 1 Challenge Level: Challenge Level:1

George wrote to us and described a way to move part of the red or green discs using fractions.

He said to make the green $\frac{1}{3}$ and the red $\frac{2}{3}$.

So, something like this:


green 1/3 and red 2/3

However George didn't say what he was showing by turning in this way. I like the way you've described where the turning finishes, George.


Perhaps you have some ideas?

Can you describe how you would move the discs?

You might have some other ways of explaining what happens. Please don't worry that your solution is not "complete" - we'd like to hear about anything you have tried. Teachers - you might like to send a summary of your children's work.
