9 Autumn 2

Coordinate Geometry

This unit of work builds on work from Year 7 Summer 1. As the current Year 9 will not have had those lessons, I have included them here as the first three lessons.

I have also added a Desmos activity “Des-Face”.

Pre-lesson 1 Coordinate squares
Pre-lesson 2 Coordinate rectangles
Pre-lesson 3 Horizontal and vertical lines
Pre-lesson 4 Des-face using Desmos – teacher guide

As several of the lessons below require the use of computers or tablets, there may be an issue with booking equipment. The starred lessons can be left out, or completed at a later date.

It is recommended that some time is spent in departments familiarising yourselves with the Desmos classroom lessons.  Here is  a simple start up guide if you have never used it before.

Lesson 2 Midpoints
