If you’re looking for a fun hands-on project that’s mathematical and Christmassy, look no further than Think Maths‘ classic Fractal Christmas trees – building a Sierpinski tetrahedron tree, Menger Sponge base and Koch Snowflake star.

You just need to print the PDFs onto the appropriate colours of card, cut out all the pieces and tape it together. They also have a gallery of photos sent in by schools and families who’ve made trees themselves, as well as some resources around fractals.

We’ve also been sent some related activity sheets for KS4, looking at the infinite properties of the Koch snowflake and series summations, put together by maths teacher Nikki.
