Fun time
Problem
On Saturday, Asha and Kishan's grandad took them to a Theme Park.
They worked out that $\frac{3}{4}$ of the rest of their time there was spent enjoying the rides.
The 3-d cinema show took up $\frac{2}{3}$ of the
rest of the day.
Finally there were $10$ minutes left to go to the gift shop before
they went home.
How long were Asha and Kishan at the Theme Park?

shopping?

Student Solutions
You all realised that you need to work backwards, or from the end of the question, to answer this problem. Thomas, Serge, Runi and Sam from Newberries Primary School all found the correct length of time that Asha and Kishan spent at the fair to be five hours. Sam explains how he worked this out:
Lucy from St John's R. C. Primary School used a pie chart to calculate the answer:
Alice and Gwen, who are both from The Downs C.E.P School, represented their solution as a rectangle:
