See links below to a few follow-on ideas and resources, based on some of the topics from Inside Maths 2026.
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: Zoe’s trick worked because she made it very likely that participants would create a multiple of 9. You may know that if you sum the digits of any multiple of 9 you will end up with a multiple of 9. Zoe adds the digits the student reads out in her head, and she works out what we need to add on to that total to get to the next multiple of 9. That must be the secret digit that has been missed out.
An easier trick that ensures everyone (where nothing is left to chance) makes a multiple of 9, is described in these teacher notes. The method for creating the number is different, but the rest of the method is the same as what Zoe was doing.

PUZZLES FROM FRAN:
Fran Watson has recommended the following puzzles from the Nrich website, that involve similar mathematical thinking skills (of visualisation etc) to those we used in her paper folding talk.
