Coordinate geometry

This module from the AMSI 'The Improving Mathematics Education in Schools (TIMES) project' is for teachers who wish to consolidate their content knowledge on the topic of coordinate geometry, including how to find the length, mid-point, gradient and equation of a line. There are sections that provide history and context for the topic, as well as exercises and examples of how to present and explain the concepts to students.
