Pupils plan quantities they will buy in order to maximise their profit from selling ice creams at a school event.
- National Curriculum levels 5 to 6
- 30 minutes to 1 hour
- Pencil, calculator and paper
Key Processes involved
- Interpret diagrams and words and select the appropriate information from them
- Work logically towards a result, recognising the impact of constraints. Calculate accurately and apply routine algorithms, making estimates and checking calculations
- Interpreting and evaluating
- Interpret their calculations in context
- Communicating and reflecting
- Show reasoning clearly
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
