Teacher guidance

Check that pupils fully understand the context, for example by explaining:

  • You are planning to make and sell ice cream cones at the school sports day. You need to calculate the costs to make sure that you don’t make a loss.
  • What points would you think about?

Pupils may tackle this task in different ways, but might be expected to:

  • solve simple problems involving ratio and direct proportion
  • calculate fractional or percentage parts of quantities and measurements, using a calculator where appropriate
  • interpret graphs and diagrams, including pie charts, and draw conclusions
