Function Families: Translations and Reflections

This comprehensive introduction to rigid transformation of functions does a fabulous job of breaking down translations and reflections into manageable concept chunks. Care is taken with horizontal translations, vertical translations, reflections, and combined transformations to explain both the why's and how's of moving points and graphs. Tables of values are used for clear explanation, and examples are worked step-by-step. This lesson makes either a great teaching supplement or a strong remediation addition to your curriculum!

Instructional Ideas
  • Give the class a before image and an after image of a graph translation. Then, have them develop the parent and translated functions
  • Perfect for viewing before class, in a flipped classroom situation, or for homework help in a traditional setting
  • Create a matching game where each learner is assigned a function and has to find every partner in their function family and identify the transformations
  • With corresponding homework activities from your curriculum, this lesson would make for an excellent highly qualified substitute plan
