Pupils determine the amount of time Santa can spend at each house in the UK when delivering presents on Christmas Eve.
- National Curriculum levels 4 to 7
- 30 minutes to 1 hour
- Calculator and paper
Key Processes involved
- Select information, make assumptions
- Use given and assumed facts to work towards a solution
- Interpreting and evaluating
- Communicating and reflecting
- Present arguments and reflect on findings, building towards a credible solution
Check that pupils fully understand the context, for example with points such as:
- Think about the information you are given and ask yourself why it would be useful in helping you to work out the average amount of time Santa can spend at each house.
- Present your solution in a letter to Santa, so he understands it and how you arrived at it. Remember to show your working and your reasoning.
During the task the following probing questions may be useful
- Have you used all the information you have been given? If not, why not?
- What else do you need to assume?
- How many hours do you think can Santa work – while children are asleep?
- Will Santa understand what you have done and why?
- What does your solution tell you about Santa’s schedule?
