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?
I was in my car crawling along the M6 motorway a few weeks ago,
thinking that it would be quicker to walk to the exhibition I was
attending, when I noticed a line of four cars on the lane next to
me with number plates starting with J, K, L and M and ending in the
same letters, though each car did not necessarily start and end
with the same letter.
The car with L as the last letter was not next to the car with L
as its first letter but was next to the one with J as the first
What were the start and end letters of each
of the number plates and what order were they in?
