Watch this "Notes on a Triangle" film. Can you recreate parts of the film using cut-out triangles?

This practical activity challenges you to create symmetrical designs by cutting a square into strips.

Have you ever noticed the patterns in car wheel trims? These questions will make you look at car wheels in a different way!

Can you recreate this Indian screen pattern? Can you make up similar patterns of your own?

It's hard to make a snowflake with six perfect lines of symmetry, but it's fun to try!

Follow these instructions to make a five-pointed snowflake from a square of paper.

What is the missing symbol? Can you decode this in a similar way?

This practical problem challenges you to create shapes and patterns with two different types of triangle. You could even try overlapping them.

Can you place the blocks so that you see the relection in the picture?

Can you make the green spot travel through the tube by moving the yellow spot? Could you draw a tube that both spots would follow?

Can you deduce the pattern that has been used to lay out these bottle tops?

What mathematical words can be used to describe this floor covering? How many different shapes can you see inside this photograph?

What is the same and what is different about these tiling patterns and how do they contribute to the floor as a whole?

This problem explores the shapes and symmetries in some national flags.

Create a pattern on the left-hand grid. How could you extend your pattern on the right-hand grid?

This practical problem challenges you to make quadrilaterals with a loop of string. You'll need some friends to help!

Use the blue spot to help you move the yellow spot from one star to the other. How are the trails of the blue and yellow spots related?

Use the interactivity to create some steady rhythms. How could you create a rhythm which sounds the same forwards as it does backwards?

Someone at the top of a hill sends a message in semaphore to a friend in the valley. A person in the valley behind also sees the same message. What is it?

Use the clues about the symmetrical properties of these letters to place them on the grid.

Systematically explore the range of symmetric designs that can be created by shading parts of the motif below. Use normal square lattice paper to record your results.

Find the missing coordinates which will form these eight quadrilaterals. These coordinates themselves will then form a shape with rotational and line symmetry.

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. . . .

This interactivity allows you to sort letters of the alphabet into two groups according to different properties.

This activity investigates how you might make squares and pentominoes from Polydron.

Use the information on these cards to draw the shape that is being described.

Mathematics is the study of patterns. Studying pattern is an opportunity to observe, hypothesise, experiment, discover and create.

Explore ways of colouring this set of triangles. Can you make symmetrical patterns?

Using the 8 dominoes make a square where each of the columns and rows adds up to 8

Plex lets you specify a mapping between points and their images. Then you can draw and see the transformed image.

An article for students and teachers on symmetry and square dancing. What do the symmetries of the square have to do with a dos-e-dos or a swing? Find out more?

Place the numbers 1, 2, 3,..., 9 one on each square of a 3 by 3 grid so that all the rows and columns add up to a prime number. How many different solutions can you find?
