Describe, name and sort polygons, including pentagons, hexagons and octagons
I can recognise and describe polygons including pentagons, hexagons and octagons.
Lesson details
Key learning points
- The names of polygons are linked to the number of sides they have.
- A pentagon is any polygon with 5 sides.
- A hexagon is any polygon with 6 sides.
- An octagon is any polygon with 8 sides.
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.
Keywords
Pentagon - A polygon with 5 sides and 5 vertices.
Hexagon - A polygon with 6 sides and 6 vertices.
Octagon - A polygon with 8 sides and 8 vertices.
