Each of the nets of nine solid shapes has been cut into two pieces. Can you see which pieces go together?
You want to make each of the 5 Platonic solids and colour the faces so that, in every case, no two faces which meet along an edge have the same colour.
Here are the six faces of a cube - in no particular order. Here are three views of the cube. Can you deduce where the faces are in relation to each other and record them on the net of this cube?
This problem invites you to build 3D shapes using two different triangles. Can you make the shapes from the pictures?
How can we as teachers begin to introduce 3D ideas to young children? Where do they start? How can we lay the foundations for a later enthusiasm for working in three dimensions?
What is the shape of wrapping paper that you would need to completely wrap this model?
Each of these solids is made up with 3 squares and a triangle around each vertex. Each has a total of 18 square faces and 8 faces that are equilateral triangles. How many faces, edges and vertices. . . .
A half-cube is cut into two pieces by a plane through the long diagonal and at right angles to it. Can you draw a net of these pieces? Are they identical?
We need to wrap up this cube-shaped present, remembering that we can have no overlaps. What shapes can you find to use?
What size square should you cut out of each corner of a 10 x 10 grid to make the box that would hold the greatest number of cubes?
What is the largest cuboid you can wrap in an A3 sheet of paper?
Which of the following cubes can be made from these nets?
In this problem you have to place four by four magic squares on the faces of a cube so that along each edge of the cube the numbers match.
