task from 'the Little Book of Big Brain Games'
by Ivan Moscovich

the four shapes have to completely fill the space

some students might appreciate that each shape needs to have 2 squares (8 divided by 4) in the inner ring and 4 (16 divided by 4) in the outer ring - which makes this task a lot easier (thanks to Jenni Ingram, Oxford Uni. for this insight).
