Unit 5: Transformations

Overview

Ever wondered how to teach transformations in an engaging way to your 8th-grade students?

In this unit plan, students will first learn about translations, then move on to reflections and rotations. Lastly, they will explore dilations, scale factors, and similar figures.

Each lesson helps students master the unit through artistic, interactive guided notes and check for understanding. The unit culminates with a real-life example that explores how transformations are applied in real-world scenarios.

It's an exciting way to teach transformations while comprehensively meeting standards.

Learning Objectives

After this unit, students will be able to:

  • Perform translations of figures on a coordinate plane using arrow notation.

  • Write rules for translations of figures on a coordinate plane.

  • Graph figures on a coordinate plane that have undergone translations.

  • Reflect figures across the x-axis, y-axis, and the line y=x.

  • Perform rotations of figures about the origin at 90, 180, and 270 degrees on a coordinate plane.

  • Identify and apply scale factors in dilations of figures on a coordinate plane.

  • Determine if two figures are similar using scale factors and proportions.

  • Apply transformations such as translations, reflections, rotations, and dilations to real-life scenarios and problems.
