Draw a square. A second square of the same size slides around the first always maintaining contact and keeping the same orientation. How far does the dot travel?

Which way of flipping over and/or turning this grid will give you the highest total? You'll need to imagine where the numbers will go in this tricky task!

How will you decide which way of flipping over and/or turning the grid will give you the highest total?

These images are taken from the Topkapi Palace in Istanbul, Turkey. Can you work out the basic unit that makes up each pattern? Can you continue the pattern? Can you see any similarities and. . . .

Can you swap the black knights with the white knights in the minimum number of moves?

Introduces the idea of a twizzle to represent number and asks how one can use this representation to add and subtract geometrically.

The first part of an investigation into how to represent numbers using geometric transformations that ultimately leads us to discover numbers not on the number line.

What is the relationship between these first two shapes? Which shape relates to the third one in the same way? Can you explain why?

Does changing the order of transformations always/sometimes/never produce the same transformation?

See the effects of some combined transformations on a shape. Can you describe what the individual transformations do?

Sort the frieze patterns into seven pairs according to the way in which the motif is repeated.

Some local pupils lost a geometric opportunity recently as they surveyed the cars in the car park. Did you know that car tyres, and the wheels that they on, are a rich source of geometry?

Patterns that repeat in a line are strangely interesting. How many types are there and how do you tell one type from another?
