See links below to a few follow-on ideas and resources, based on some of the topics from Inside Maths 2025.
BINARY CARD TRICK: Teacher resources about the binary card trick (from Rob’s talk). In these resources we have included five cards in the set, so that the mathemagician can predict any number up to 31. This means you could ask your audience to find their birthday on the cards (rather than asking them to choose a favourite number): think-maths.co.uk/binary-trick
FRACTAL BUILDING: Want to make your own Sierpinski Tetrahedron back at school? Find the nets (and instructions for how to tape) at this link. The link also has resources for building other 3D fractals! https://think-maths.co.uk/resources/building-3d-fractals/
MOBIUS LOOP: Zoe introduced us to the mobius loop. Download Zoe’s Mobius Investigation Sheet HERE to try other mobius loop activities.
ZOE’S MAGIC TRICK: THIS TRICK DIDN’T ACTUALLY HAPPEN , AS WE RAN OUT OF TIME, BUT YOU CAN STILL ENJOY THE RESOURCE. Download these Teacher Notes for a trick about multiples of 9.
