Take a look at the photos of tiles at a school in Gibraltar. What questions can you ask about them?

Challenge Level

An environment that enables you to investigate tessellations of regular polygons

Challenge Level

Using LOGO, can you construct elegant procedures that will draw this family of 'floor coverings'?

Challenge Level

Show how this pentagonal tile can be used to tile the plane and describe the transformations which map this pentagon to its images in the tiling.

Challenge Level

Join pentagons together edge to edge. Will they form a ring?

Challenge Level

Semi-regular tessellations combine two or more different regular polygons to fill the plane. Can you find all the semi-regular tessellations?

Challenge Level

Can you make a regular hexagon from yellow triangles the same size as a regular hexagon made from green triangles ?

Challenge Level

A triomino is a flat L shape made from 3 square tiles. A chess board is marked into squares the same size as the tiles and just one square, anywhere on the board, is coloured red. Can you cover the. . . .

Challenge Level

Three examples of particular tilings of the plane, namely those where - NOT all corners of the tile are vertices of the tiling. You might like to produce an elegant program to replicate one or all. . . .

This article explores the links between maths, art and history, and suggests investigations that are enjoyable as well as challenging.

Challenge Level

If the yellow equilateral triangle is taken as the unit for area, what size is the hole ?

This article describes the scope for practical exploration of tessellations both in and out of the classroom. It seems a golden opportunity to link art with maths, allowing the creative side of your. . . .

Have you ever noticed how mathematical ideas are often used in patterns that we see all around us? This article describes the life of Escher who was a passionate believer that maths and art can be. . . .

Challenge Level

Can you recreate these designs? What are the basic units? What movement is required between each unit? Some elegant use of procedures will help - variables not essential.

Challenge Level

L triominoes can fit together to make larger versions of themselves. Is every size possible to make in this way?

Challenge Level

are somewhat mundane they do pose a demanding challenge in terms of 'elegant' LOGO procedures. This problem considers the eight semi-regular tessellations which pose a demanding challenge in terms of. . . .
