Middle Grades Math: Transformers in the Classroom
by Texas Instruments

Published on November 24, 2011


  • Students will trace over different objects, digitize them, and then manipulate the ordered pairs that represent the shape to transform it in various ways.


  • dilation
  • translation
  • rotations
  • reflections
  • transformation
  • digitizing
  • coordinate

About the Lesson

This lesson involves digitizing an image and transforming it on a graph.
As a result, students will:

  • Use the drawing tool to trace over an image on a Geometry page.
  • Manipulate the shape’s coordinates in a spreadsheet to Dilate, Translate, Rotate, and Reflect it.
  • Decide how to alter the lists of points and then look at the transformed shape with the original in a graph.
  • Experiment and demonstrate alternative solutions to each transformation.
