Reflections

In this activity, students investigate reflections on a coordinate grid.

See the attached PDF file for detailed instructions for this activity

Students will:

Apply transformations and use symmetry to analyze mathematical situations

Describe sizes, positions, and orientations of shapes under informal transformations such as flips, turns, slides, and scaling

Review student answers

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
