Maths resource of the week 17

Maths resource of the week 17

Each week Craig Barton, creator of, picks out a TES maths resource that has caught his eye and records a short video about it. These videos will attempt to explain why Craig likes the resource, and offer up a few ideas about how it might be used in the classroom. If you have watched the video, downloaded the resource, and then used it in a lesson, it would be fantastic if you could return to this page to share your thoughts and ideas in the Comments section below, or to simply pass on your thanks to the author!

The Painted Cube is one of my all time favourite thought exercises, and it is a great one to throw at students at the start or end of a lesson. Students are challenged to visualise a 3x3x3 cube which has its outside painted. Now, how many of those 27 little cubes have one side painted, 2 sides painted and 3 sides painted? If, like me, your students have trouble visualising this, then this resource has an amazing flash file accompanying it which allows you to break up the cube and look at each individual face. Better still, this then leads onto a challenging investigation about working out how many sides are painted for any size of cube, which brings in some lovely algebra. A very nice resource indeed.
