This is a complete lesson on equations of vertical and horizontal lines that explores the relationship between an equation and a graph, and looks at how to recognise the equations or plot graphs of lines parallel to the axes. The lesson is designed with the new GCSE specification in mind.

- To understand the link between equations and straight line graphs.
- To plot and draw graphs parallel to the axes, and y = x and y = -x.
- To recognise the equations of lines parallel to the axes.

This pack is designed for GCSE higher or foundation tier students. It could also be used with Key Stage 3 students.

Included in this download are the following:

- Full lesson plan for the ‘Equations of Vertical and Horizontal Lines’ lesson, including introduction, teaching content, individual activities, plenary and suggested support and extension activities
- Coordinates Introduction
- Mini-Plenary
- y=x Demonstration
- Mini-Plenary
- Student Worksheet on Equations of Vertical and Horizontal Lines
- Rectangle Plenary
