Here we have some arrangements of cubes. Each one is made of three cubes and is coloured differently. We will call these 'triples'.
 
What do you notice about them?
 
You could get 8 triple cubes like these, each triple a different colour. Don't separate the triple but use them as building blocks to see what you can make.
 
It would be good to keep the eight triple cubes facing the ways they are in the picture, and not turn them around. In this way, each triple will be different.
 
We can now use these as building blocks to make interesting arrangements and shapes. Here is one to start us off.

Notice how I've joined them together with square faces touching. This might be the way that you decide to build.
 
Or, you may include some 'edge' joining like in this one:

Now it's your turn! What can you make from these eight triple cubes?
