With this unique and intriguing trick, explore the connections between movements on a grid and maths. Plus, the whole class can participate; everyone gets a chance to try a different move!

- This trick focuses on parity. If the maze is viewed as a checkerboard, logic can be used to know exactly which squares to remove. Plus, the students can come up with extensions: a 3 by 3 grid is small. They can try with one that is bigger and is a different shape. This trick can lead to fun mathematical explorations over a longer period of time.
