This article for students gives some instructions about how to make some different braids.
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?
Here is a solitaire type environment for you to experiment with. Which targets can you reach?
This package contains hands-on code breaking activities based on
the Enigma Schools Project. Suitable for Stages 2, 3 and 4.
In this article for teachers, Bernard uses some problems to suggest
that once a numerical pattern has been spotted from a practical
starting point, going back to the practical can help explain. . . .
A description of how to make the five Platonic solids out of paper.
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.
How many differently shaped rectangles can you build using these
equilateral and isosceles triangles? Can you make a square?

Galileo, a famous inventor who lived about 400 years ago, came up
with an idea similar to this for making a time measuring
instrument. Can you turn your pendulum into an accurate minute
You could use just coloured pencils and paper to create this
design, but it will be more eye-catching if you can get hold of
hammer, nails and string.
Starting with four different triangles, imagine you have an
unlimited number of each type. How many different tetrahedra can
you make? Convince us you have found them all.
Use the tangram pieces to make our pictures, or to design some of
It might seem impossible but it is possible. How can you cut a
playing card to make a hole big enough to walk through?
I start with a red, a blue, a green and a yellow marble. I can
trade any of my marbles for three others, one of each colour. Can I
end up with exactly two marbles of each colour?

it's your turn! Play one of the bells yourself. How do you know
when it is your turn to ring?
Design and construct a prototype intercooler which will satisfy agreed quality control constraints.
Can Jo make a gym bag for her trainers from the piece of fabric she has?
Use the interactivity to play two of the bells in a pattern. How do
you know when it is your turn to ring, and how do you know which
bell to ring?

patterns of your own.
Make some celtic knot patterns using tiling techniques
Make a clinometer and use it to help you estimate the heights of

Interior angles can help us to work out which polygons will
tessellate. Can we use similar ideas to predict which polygons
combine to create semi-regular solids?
Learn how to draw circles using Logo. Wait a minute! Are they really circles? If not what are they?
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.
