In search of engaging maths
topics for the end of term wind-down period I dredged up pentominoes from
somewhere in my memory and quickly managed to identify for myself the twelve unique
figures that can be made from joining five squares together along their edges,
but what I could not do was fit them together to make any of the four possible
rectangles; the internet showed me how and more entertainingly how to arrange
them to make various animal shapes – cat (or dog), camel, giraffe, elephant,
kangaroo and crocodile – of which I attempted the latter, producing (after the
best part of an hour) a close relative with two tails.
