Platonic SolidsIdentify the names, nets and features of the five regular polyhedra. |
This is level 3: count the number of faces on each solid.
Faces are the flat surfaces that make up the sides of a polyhedron. They are sometimes called sides e.g. a dice has six sides.
InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file. |

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 25 June 'Starter of the Day' page by Inger.kisby@herts and essex.herts.sch.uk, : "We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much Comment recorded on the 10 September 'Starter of the Day' page by Carol, Sheffield PArk Academy: "3 NQTs in the department, I'm new subject leader in this new academy - Starters R Great!! Lovely resource for stimulating learning and getting eveyone off to a good start. Thank you!!" |

A three-dimensional solid shape with flat polygonal faces, straight edges, and sharp vertices.
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.
