What This Standard Means
What Students Need to Do
- Students determine which translations, rotations, reflections, or dilations connect two figures or return one figure to its starting position. They specify the order and parameters for each move.
What Mastery Looks Like
- Students can describe and verify a working sequence using precise transformation names and parameters. They can recognize symmetry and explain whether the final figure is congruent or only similar.
Common Misconceptions
- Students may ignore that changing the order of transformations can change the result. They may use the wrong rotation center, reflection line, translation vector, or dilation scale factor.
How to Assess It
- Give two coordinate figures and ask students to list a sequence that matches them, including all needed parameters. Have them state whether each move preserves size.

Ways to Teach It
Use tracing paper to slide, turn, flip, and resize a polygon, then record each move and its measurements.
Display two figures and ask, “Which moves match the first with the second, and why does order matter?”
Play Transformation Relay: teams draw move cards, apply them to a coordinate figure, and challenge another team to reverse the sequence.
Use floor-plan symbols at different scales to match repeated shapes through rotations, reflections, translations, or dilations.
