Non-Verbal Reasoning 3D Aid- 11 plus Magnetic Cube Net CEM

Product Information

For each net, six faces are connected by five edges Have students share and write what they learned about a cube.

This resource is great for key stage 2 maths lessons on geometry, measurement and the nets of 3D shapes. If you enjoyed this Net of a Cube paper template, we have more resources to use either in the classroom or at home.There are a total of 11 distinct nets for the cube (Turney 1984-85, Buekenhout and Parker 1998, Malkevitch), illustrated above, the same number Note: If the students happen to not produce different nets, the teachers can unfold their one in a different way as a stimulus to look for others. It is also not necessary to be told before beginning the investigation that there are 11 nets. The mathematician who first investigated these didn't know that. However, if the investigation languishes, it is a fact that can be dropped in to revitalise the search.

If you're wanting an additional challenge, why not create an Egyptian pyramidor even a tetrahedron. How can I use this cube template in lessons and at home? This cameo has a From The Classroom section which includes photos of the students' gallery of solutions and slideshows from two students showing how they can fold particular nets into cubes.It is almost certain that at least two students will have a different result. Collect these into a gallery and this begins the discussion based around how many of these flat shapes can be made within rules. The word net does not have to be defined before starting. It can be introduced as the investigation proceeds. Next, students work together in groups of four, using the two-inch squares, to come up with as many different nets for a cube as possible. Give each group two sets of 6 so that everyone in the group has a chance to try out their ideas. Once they think they have a net, have them prove that it works by copying the net onto the 2" grid paper, cutting it out and folding it into a cube. You may want to show the whole class the first few working nets that are discovered. You can make it into a competition to keep students focused. The group with the most different nets for a cube is the winner. As shown below, her preparation was based on the companion Maths300 lesson, to which she added the whiteboard dot paper, slide show and Task Centre record sheet.

Using so-called "wallet hinges," a ring of six cubes can be rotated continuously (Wells 1975; Wells 1991, pp.218-219).

When the square faces of a cube are separated at the edges and laid out flat they make a two dimensional figure called a net. There are eleven different nets for a cube. J.
