For example
A domino tile is made of two equal squares joined together.
In Grade 1
Children check that all four sides match, by folding or by measuring with a strip of paper, before naming a square.
Watch out for
Children often call any four sided shape a square. All four sides must be the same length, not just the corners square.
Say it at home
Fold a sheet of paper so the sides match and ask your child why it is now a square.
