How many ways can you find to make a yellow rod using yellow and white rods?
In this activity, children have an environment for exploring partitioning of numbers. Of course, it is essential to have cuisenaire rods available for them, so that they can solve this problem practically too. These notes are written to suggest that the activity could be used to focus on sharing good strategies to find all possibilities. These strategies can then be applied to further challenges.
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.
