This practical challenge invites you to investigate the different
squares you can make on a square geoboard or pegboard.
This activity investigates how you might make squares and pentominoes from Polydron.
If you had 36 cubes, what different cuboids could you make?
Each box is to contain $36$ sweets placed in lines in a single
layer in a geometric shape without gaps or fillers.
How many different shaped boxes can you design?
The sweets come in $4$ colours, $9$ of each colour.
Arrange the sweets so that no sweets of the same colour are
adjacent to (that is 'next to') each other in any direction. In the
diagram below none of the squares marked x can have a red sweet in
Arrange the sweets in some of the boxes you have drawn.
Now try making boxes of $36$ sweets in $2$, $3$ or $4$
Can you arrange the sweets, $9$ each of $4$ colours, so that
none of the same colour are on top of each other as well as not
adjacent to each other in any direction?
See if you can invent a good way of showing your
