The Magic of Maths – become a Maths Magician

You may be surprised to learn that there is a lot of mathematics behind magic, and by giving your students maths magic tricks to investigate, you and your class can learn new applications of mathematics and become maths magicians. You will find that these activities can be engaging for even the most reluctant maths student.

The following simple illusion is just one example that intrigues young and old alike. Cut along the dotted line and slide the lower half along by one face and magically one of the faces vanishes! Challenge your students to draw their own illusion. Start with something simple like a picture of pencils, blocks or hats.






The website Geometrical Vanishes is a good place to start when looking at visual magic


Some more Visual Maths Magic can be investigated with the area of these shapes.




This set of four pieces is called Hooper’s Paradox. The top rectangle has an of area of 30 (10x3) and can be rearranged into the bottom shape, which is made up of two rectangles. Strangely these two rectangles have a combined area of 32 (2x6 + 4x5 ). When the magician performs this trick he exclaims how he has gained 2 more pieces for free.


To see Hooper’s Paradox being performed by a professional magician play this video to your students, then ask them to make cardboard versions of Hooper’s Paradox and investigate how it works.


Websites on Mathematical Magic


Google – Maths Magic on YouTube and you will discover hundreds of videos.

One of my favourites is “Math magic card trick!!” as it shows two teenagers demonstrating a card trick in the park. At the end of the video one of the teenagers says “How does it do it, I don’t know!”

What a great place to start the lesson with your class…..
