    Here is an incomplete net for making a cube. Complete it in at least two different ways. Remember that a cube has six faces. How many are there in the net here? (Give two separate diagrams. If you like, you may use a squared sheet for easy manipulation.)

    Dice are cubes with dots on each face. Opposite faces of a die always have a total of seven dots on them.

    Here are two nets to make dice (cubes); the numbers inserted in each square indicate the number of dots in that box.

    Insert suitable numbers in the blanks, remembering that the number on the opposite faces should total to 7.
