Clocks
Age 7 to 11 Challenge Level:
These clocks have been reflected in a mirror. What times do they say?
2010: A Year of Investigations
Age 5 to 14
This article for teachers suggests ideas for activities built around 10 and 2010.
Times
Age 7 to 11 Challenge Level:
Which times on a digital clock have a line of symmetry? Which look the same upside-down? You might like to try this investigation and find out!
Hidden Meaning
Age 7 to 11 Challenge Level:
What is the missing symbol? Can you decode this in a similar way?
Coordinating Classroom Coordinates
Age 7 to 11
This article describes a practical approach to enhance the teaching and learning of coordinates.
Reflector ! Rotcelfer
Age 7 to 11 Challenge Level:
Can you place the blocks so that you see the reflection in the picture?
Shady Symmetry
Age 11 to 14 Challenge Level:
How many different symmetrical shapes can you make by shading triangles or squares?
Making Maths: Indian Window Screen
Age 7 to 11 Challenge Level:
Can you recreate this Indian screen pattern? Can you make up similar patterns of your own?
Reflecting Lines
Age 11 to 14 Challenge Level:
Investigate what happens to the equations of different lines when you reflect them in one of the axes. Try to predict what will happen. Explain your findings.
Hexpentas
Age 5 to 11 Challenge Level:
How many different ways can you find of fitting five hexagons together? How will you know you have found all the ways?
Paint Rollers for Frieze Patterns.
Age 11 to 16
Proofs that there are only seven frieze patterns involve complicated group theory. The symmetries of a cylinder provide an easier approach.
The Frieze Tree
Age 11 to 16
Patterns that repeat in a line are strangely interesting. How many types are there and how do you tell one type from another?
National Flags
Age 7 to 11 Challenge Level:
This problem explores the shapes and symmetries in some national flags.
It's Times Again
Age 7 to 14 Challenge Level:
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!
So It's Times!
Age 7 to 14 Challenge Level:
How will you decide which way of flipping over and/or turning the grid will give you the highest total?
Building with Longer Rods
Age 7 to 14 Challenge Level:
A challenging activity focusing on finding all possible ways of stacking rods.
Let Us Reflect
Age 7 to 11 Challenge Level:
Where can you put the mirror across the square so that you can still "see" the whole square? How many different positions are possible?
Shaping up with Tessellations
Age 7 to 14
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. . . .
Frieze Patterns in Cast Iron
Age 11 to 16
A gallery of beautiful photos of cast ironwork friezes in Australia with a mathematical discussion of the classification of frieze patterns.
...on the Wall
Age 11 to 14 Challenge Level:
Explore the effect of reflecting in two intersecting mirror lines.
Matching Frieze Patterns
Age 11 to 14 Challenge Level:
Sort the frieze patterns into seven pairs according to the way in which the motif is repeated.
Friezes
Age 11 to 14
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?
Penta Play
Age 7 to 11 Challenge Level:
A shape and space game for 2,3 or 4 players. Be the last person to be able to place a pentomino piece on the playing board. Play with card, or on the computer.
Transformation Tease
Age 7 to 11 Challenge Level:
What are the coordinates of this shape after it has been transformed in the ways described? Compare these with the original coordinates. What do you notice about the numbers?
Transformation Game
Age 11 to 14 Challenge Level:
Why not challenge a friend to play this transformation game?
Transforming the Letters
Age 7 to 11 Challenge Level:
What happens to these capital letters when they are rotated through one half turn, or flipped sideways and from top to bottom?
Decoding Transformations
Age 11 to 14 Challenge Level:
See the effects of some combined transformations on a shape. Can you describe what the individual transformations do?

Age 11 to 14 Challenge Level:
Does changing the order of transformations always/sometimes/never produce the same transformation?
Simplifying Transformations
Age 11 to 14 Challenge Level:
How many different transformations can you find made up from combinations of R, S and their inverses? Can you be sure that you have found them all?
