Lesson details
Key learning points
- Three points on a geoboard can be joined to make a triangle.
- Triangles can have different properties.
- Different triangles can be created on the same geoboard.
Keywords
Vertex / vertices - A vertex is the point where two lines meet. The plural is vertices.
Perpendicular - Two lines which meet at a right angle are perpendicular.
Common misconception
Pupils may overgeneralise about the way a triangle should look e.g. not recognising a scalene triangle as a triangle.
Throughout the lesson, model different triangles in different orientations. Ensure pupils see boundary examples such as scalene triangles with one very small acute angle, or long and thin isosceles triangles.
