This resource pack is designed to help students grasp the concept of locus. It focuses on helping students to visualise and understand what is meant by a "locus of points". The resource could be used as an introduction to the topic of locus and could be followed up by lessons on the techniques of construction used to create accurate loci drawings. (Construction methods are not covered in this resource.)

The resource pack includes:

• Starter activity:
  1. objectives
