Loci

Overview

Mobile phone technology, guide dog training and finding somewhere to live are used to illustrate simple loci. Basic construction techniques are explored alongside these real contexts, and the concept of regions is developed. Presenters Jamie and Katie investigate the main loci tested in examinations and show how compasses can be used to draw these accurately.

The programme aims to help students to understand how a path of points is built by using dynamic visual images and demonstrations. A mixture of real-life and abstract content is developed simultaneously, alongside detailed instruction on compass constructions. Appropriate maps and scales are used and explained. The topic is presented in a lively, interesting and entertaining style. The content is linked throughout to the requirements of GCSE Intermediate Mathematics. It includes tips for answering examination questions and a discussion of a typical exam error in the 'Tick or Trash' section. The programme exploits the power of television to produce clear graphic and visual explanations that should enhance the teaching of this topic. The content is chosen to engage the student audience, as well as to support teachers by bringing the outside world into the classroom.
