Key Stage: 2 ★
How many ways are there to place two green cubes on top of two red cubes so that the two green cubes touch? What about if there are three or four red cubes?
This problem involves many aspects of mathematics, both content and processes, and it is a good one to introduce investigative approaches. Children will be counting and developing spatial awareness, and you can use it to highlight working systematically, representing and making conjectures.
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.
