Transformations 3 - Reflections and Revision

Activity Overview

Beyond sliders and memorising, students  need a good understanding of the reasoning behind transformations. This activity is the third part in the series, focusing on the algebra behind reflections, plus a review of parts one and two. 


The aim of this activity is for students to develop an understanding of reflections through algebra rather than memorising formats. This activity also includes revision of dilations and translations.


  • Transformation
  • Reflection
  • Towards or Away from axis

About the Lesson

Students can edit the algebra that defines the reflected point. The discrete connection between the algebra and the visual helps students understand the connections.
