Here are shadows of some 3D shapes. What shapes could have made
Here are some pictures of 3D shapes made from cubes. Can you make
these shapes yourself?
Which of these dice are right-handed and which are left-handed?
Can you arrange the shapes in a chain so that each one shares a
face (or faces) that are the same shape as the one that follows it?
Each of the nets of nine solid shapes has been cut into two pieces. Can you see which pieces go together?
Chloe, Kaan and Rachel all worked on this problem practically to make sense of the patterns they found.
Go to last month's problems to see more solutions.
How can we as teachers begin to introduce 3D ideas to young

later enthusiasm for working in three dimensions?
This is a challenging game of strategy for two players with many interesting variations.
