NRICH - Two Clocks

Time
Key Stage: 2 ★

Sam's clock only has an hour hand. Julie's clock only has a minute hand. Can you determine which events happened when their clocks showed these displays?

This problem can help children understand that analogue clocks are really two scales superimposed, which makes it so difficult to read. Focusing on the hands separately helps children understand what each one indicates. The novel context of this problem could provide a good assessment opportunity.
The problem lends itself to collaborative working for children who are either inexperienced in group work or used to working in this way.

This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
