Logo helps us to understand gradients of lines and why Muggles Magic is not magic but mathematics. See the problem Muggles magic.

You could use just coloured pencils and paper to create this design, but it will be more eye-catching if you can get hold of hammer, nails and string.

Learn how to draw circles using Logo. Wait a minute! Are they really circles? If not what are they?

In this article for teachers, Bernard uses some problems to suggest that once a numerical pattern has been spotted from a practical starting point, going back to the practical can help explain. . . .

These are pictures of the sea defences at New Brighton. Can you work out what a basic shape might be in both images of the sea wall and work out a way they might fit together?

It might seem impossible but it is possible. How can you cut a playing card to make a hole big enough to walk through?

Exploring balance and centres of mass can be great fun. The resulting structures can seem impossible. Here are some images to encourage you to experiment with non-breakable objects of your own.

This part introduces the use of Logo for number work. Learn how to use Logo to generate sequences of numbers.

A game in which players take it in turns to choose a number. Can you block your opponent?

Interior angles can help us to work out which polygons will tessellate. Can we use similar ideas to predict which polygons combine to create semi-regular solids?

Here is a chance to create some Celtic knots and explore the mathematics behind them.
