Fun activity for your kids at home:
Take a square of paper or cardboard, and cut it into four pieces, as shown.
Now try to put them back in the form of a square.
This seemingly simple puzzle, has kept our young people busy a whole evening, and was only accomplished at last by marking each piece before it was cut apart.
