To play the game you need a gameboard, one die, one counter for each player and paper and pencil for recording scores
Rules: REGULAR POLYPATH GAME Players in turn roll the die and move their counter that number of spaces. When they land on a shape, they must imagine that a regular […]
This is a puzzle and game for 2 players or 2 teams. When you first meet it, play cooperatively rather than competitively. First think of this as a puzzle. Match the regular polygons with stars so that each polygon-star pair has a different shape combination to all the others, showing a different […]
The picture shows some shadows cast by solid (3 dimensional) objects as well as some flat (2 dimensional) shapes.
Describe 3D objects that could have made these shadows. There is more than one answer for each shadow.
Can you draw different shadows that could be made by the same objects?
What sort of shadows […]
A regular polygon has all its angles equal and all edge lengths equal. In a regular polyhedron all the faces are congruent regular polygons and the same number of polygons meet at each vertex.
Each regular polyhedron has its own codename. The tetrahedron is 333, the octahedron is 3333, the icosahedron is […]
Some arrangements of six squares form the net of a cube, others do not. Explain why the two shaded arrangements are nets of cubes and the two unshaded arrangements are not.
Draw this net and make your own cube.
How many faces, edges and vertices does a cube have?

First make 6 paper sticks, all the same length, by rolling paper tightly round pieces of string and securing with sticky tape. Then make a rhombus by tying together 5 sticks to make 2 equilateral triangles. Use the rhombus and the one remaining stick to make a shape with […]
Make 6 paper sticks, all the same length, by tightly rolling a piece of paper around a piece of string and securing it with sticky tape. If you have not made paper sticks before see the video: https://youtu.be/iaJ6EitIGKU
A tetrahedron (plural tetrahedra) is a solid with four triangular faces. How many different tetrahedra can you make using the four different types of triangle shown in the diagram if you have an unlimited number of each type?
Type R are right angled isosceles triangles with sides a, a and b units.
Type […]
This practical activity involves making a skeletal model of an icosahedron by tying together sticks made from paper rolled tightly around pieces of string. Make 6 rhombuses as shown with 5 sticks for each one.
Tie the rhombuses together to make this pattern noting how the different coloured rhombuses […]
In these activities you will investigate the properties of prisms and pyramids. Full instructions are given as to how to roll scrap paper tightly around string to make paper sticks and tie the string together at the vertices to make ‘skeleton’ 3D polyhedra. There are activities for teachers to engage with together […]
