TES Maths Resource of the Week

Resource title: Volume and surface area codebreakers

Resource author: alutwyche

What is it?

I love codebreakers! In fact, I love them so much that I dedicated a section of this blog post to them back in October. But these two are particularly great as they test students' understanding of 3D measures, rather than just the usual number or algebra topics.

In this resource, there are two worksheets: the first covers cubes, cuboids and cylinders, while the second focuses on spheres, cones and pyramids. They are ideal for both higher and foundation pupils as both papers require a familiarity with non-prisms.

How can it be used?

The beauty of codebreaker activities is that they pretty much run themselves. And, helpfully, they are suited to both independent and group work.

Differentiation is quite straightforward, too. Why not support less-able students by giving them a formula sheet, or extend more-able learners by getting them to create their own?

For a real challenge, ask pupils to change the resulting codeword by creating questions to match the answers already given. Very tricky indeed!
