Make and draw quadrilaterals on circular geoboards

Lesson details

Learning outcome

I can make and draw quadrilaterals on circular geoboards and name quadrilaterals according to their properties.

Key learning points

  1. Join four dots on the edge of the circle to create a quadrilateral.
  2. Use the properties of the quadrilateral to decide if the quadrilaterals are different or the same.
  3. Work systematically to create all the different possible quadrilaterals.

Keywords

  • Quadrilateral - A quadrilateral is a polygon with four straight sides and four vertices.

  • Vertex / vertices - A vertex is the point where two lines meet. The plural is vertices.

  • Parallel - Parallel lines are straight lines that are always the same distance apart. They never get closer together or further apart.

Common misconception

Pupils find remembering the types and properties of quadrilaterals challenging.

Take time to repeat and revisit the key properties within the lesson and beyond. Consider providing a scaffold for some pupils so they can create quadrilaterals without having to recall the specific properties each time.

Teacher tip

This lesson focuses on different types of quadrilaterals. Take time to ensure that you have a secure understanding of the definitions of each. You may wish to create some unusual examples to share.
