This Instructional Activity is a part of the Lesson 5, Unit 1, Grade 8. While the warm-up focuses on studying translations using a coordinate grid, the goal of this activity is for students to work through multiple examples of specific points refiected over the x-axis and then generalize to describe where a reflection takes any point. In the next activity, students will study 90 degree rotations on a coordinate grid, rounding out this preliminary investigation of how transformations work on the coordinate grid.
