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

Product Information

Is it in Maths With Attitude? Maths With Attitude is a set of hands-on learning kits available from Years 3-10 which structure the use of tasks and whole class investigations into a week by week planner.

Today students will use their knowledge of attributes of cubes, work together in groups and find as many ways as possible to make a cube. A two-dimensional pattern for a three-dimensional shape is called a "net." A net of a cube is defined and students are asked to find the 11 different nets which can fold up to make a cube. The rectangles are drawn next to each other, joined along the dimension that is the length of the prism. 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.To find all the nets now requires careful application of the strategy of Try every possible case. For example, begin with 4 squares in a line and one on the end making an 'l' shape. Take the sixth square 'for a walk' around this L and place it in every possible position. Record those possibilities which make cube nets. Repeat with 4 squares in a line and the fifth square making a 't' shape, and so on. This resource is great for key stage 2 maths lessons on geometry, measurement and the nets of 3D shapes. For each net, six faces are connected by five edges Have students share and write what they learned about a cube. 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.

There are other regular polyhedra (tetrahedron, octahedron etc.). How many nets can you find for each of these?A cube consists of six square faces, twelve edges, and eight vertices. 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.
