Common misconception
Children may say that they do not know the name of a polygon when it is an irregular and it does not look familiar to them.
Show children a wide range of pentagons and count the sides and vertices of each shape. Agree that these shapes are all pentagons even though they all look different. Repeat with hexagons and octagons.
