How many balls of modelling clay and how many straws does it take
to make these skeleton shapes?
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?
Here are shadows of some 3D shapes. What shapes could have made
Each of the nets of nine solid shapes has been cut into two pieces. Can you see which pieces go together?
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?
60 pieces and a challenge. What can you make and how many of the
pieces can you use creating skeleton polyhedra?
A very mathematical light - what can you see?
These models have appeared around the Centre for Mathematical Sciences. Perhaps you would like to try to make some similar models of your own.
In a recent workshop, students made these solids. Can you think of
reasons why I might have grouped the solids in the way I have
before taking the pictures?
