This article for pupils gives an introduction to Celtic knotwork patterns and a feel for how you can draw them.
Have a go at drawing these stars which use six points drawn around a circle. Perhaps you can create your own designs?
What happens to the area of a square if you double the length of the sides? Try the same thing with rectangles, diamonds and other shapes. How do the four smaller ones fit into the larger one?
Imagine you have an unlimited number of four types of triangle. How many different tetrahedra can you make?
Let's say you can only use two different lengths - 2 units and 4 units. Using just these 2 lengths as the edges how many different cuboids can you make?
In this challenge, you will work in a group to investigate circular fences enclosing trees that are planted in square or triangular arrangements.
Looking at the picture of this Jomista Mat, can you decribe what you see? Why not try and make one yourself?
The triangle ABC is equilateral. The arc AB has centre C, the arc BC has centre A and the arc CA has centre B. Explain how and why this shape can roll along between two parallel tracks.
I start with a red, a green and a blue marble. I can trade any of my marbles for two others, one of each colour. Can I end up with five more blue marbles than red after a number of such trades?
How can you make a curve from straight strips of paper?
This is a simple paper-folding activity that gives an intriguing result which you can then investigate further.

How can you put five cereal packets together to make different shapes if you must put them face-to-face?
Make a flower design using the same shape made out of different sizes of paper.
Can you work out what shape is made by folding in this way? Why not create some patterns using this shape but in different sizes?
This problem invites you to build 3D shapes using two different triangles. Can you make the shapes from the pictures?
In how many ways can you fit two of these yellow triangles together? Can you predict the number of ways two blue triangles can be fitted together?

Ideas for practical ways of representing data such as Venn and Carroll diagrams.
Exploring and predicting folding, cutting and punching holes and making spirals.
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.
As part of Liverpool08 European Capital of Culture there were a huge number of events and displays. One of the art installations was called "Turning the Place Over". Can you find our how it works?
Can you each work out what shape you have part of on your card? What will the rest of it look like?
