Kjartan Poskitt, author of the Math Maze series and Runaway Pea series, introduces his new Mega Maths Maze full of pathways, traps and creatures. Once you’ve found your way through the river rapids, spooky forest and deep dark caves, you get to unlock the secret doors and go back to learn more about the strange world of numbers. He’ll also show some of the weird tricks and games from his Murderous Maths series including his fabulous flexagons, and how to make a dragon from a cinema ticket!
