Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 3 October 'Starter of the Day' page by Mrs Johnstone, 7Je: "I think this is a brilliant website as all the students enjoy doing the puzzles and it is a brilliant way to start a lesson." Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" |

A special type of polyhedron where all faces are identical regular polygons, all vertices have the same number of faces meeting, and all edges are the same length. There are five types: Tetrahedron, Cube, Octahedron, Dodecahedron, and Icosahedron.
A two-dimensional layout of the faces of a polyhedron, arranged so that when folded along the edges, it forms the corresponding 3D shape.
The flat surface of a polyhedron, typically a polygon, that forms one of its sides.
The point where two or more edges of a polyhedron meet.
The straight line where two faces of a polyhedron meet, connecting two vertices.
