Lesson details
Key learning points
- A polygon has straight sides.
- The sides of a polygon meet at vertices.
- A polygon is a 2D shape.
- Polygons can be sorted in different ways.
- Properties of polygons include the number of sides and the number of vertices.
Keywords
Polygon - A 2D shape made up of 3 or more straight sides.
2D / two dimensional - A shape with only two measurable dimensions, e.g. width and length, but no thickness.
Sides - The outside edges of a shape.
Vertices - A vertex is the point where two lines meet. The plural is vertices.
Common misconception
Some children might not count the sides or vertices accurately because they lose track of where they started counting.
Ask children how they can make sure they only count each side or vertex once. Model marking each side or vertex as you count it.
