Lesson details

Key learning points

  1. Different patterns on the paper allow you to draw polygons with different properties.
  2. A ruler helps to draw shapes accurately.
  3. Mark the vertices of the shape and join them with a ruler to create polygons.

Keywords

  • Isometric - Isometric means distances between points stay the same. In this lesson we use isometric paper which has equally spaced dots or points.

  • Perpendicular - Two lines which meet at a right angle are perpendicular.

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

Common misconception

Pupils may not identify when a polygon has more than one pair of parallel or perpendicular sides especially when the polygon is not a rectangle.

Make use of right angle checkers to identify that some shapes have more than one right angle and take time to link this to perpendicular sides.

This lesson uses isometric paper of different types. You may wish to pre-prepare some additional paper so that pupils can explore creating lots of different polygons.
