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 […]
The edges of the triangle are the same length. […]
A tetrahedron and an octahedron, both have equilateral triangular faces.

You will find instructions for making all sorts of mathematical models and learning aids from very cheap materials that will help you to learn, understand and enjoy mathematics […]
Imagine dipping the large cube into a pot of yellow paint so the whole outer surface is covered. What is its surface area?
Now imagine breaking the […]
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 […]
How many faces, edges and vertices does a cube have?
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.
Here are the nets of 9 solid shapes.
Each net has been cut into 2 pieced like the net of the cube.
Can you see which pieces […]
