• Professor Fiendishs fatal fungus

2

• Professor Fiendish has trapped you in his
  bathroom.
• On the floor is a huge patch of fatal fungus
  which is about to fire its rot spores all over
  the room.
• The only way to save yourself is to cover up the
  patch of fungus, not even a tiny bit must be left
  uncovered.

3

• All you have to cover the fungus with is a set of
  square tiles which are all exactly the same size

4
That was easy
Unluckily, Professor Fiendish realises it is too
easy with square tiles! He takes them away and
shows you some shapes like this
5
You have to choose one of the shapes, and he will
give you a set of tiles of that shape.
Does it matter which shape you choose to cover
the fungus with, or do you think that some shapes
will not work?

CIRCULAR TILES

So which of the Professors shapes would work and
which would not?
Remember, the edges of your pattern dont have to
be neat, just as long as there are no gaps in the
middle.
Try the Professors shapes and put your results
into a table. Then try some shapes of your own.
