This document is a lesson plan on symmetry in the coordinate plane. It includes student learning outcomes around recognizing when two ordered pairs differ only by sign of one or both coordinates, indicating a reflection across one or both axes. Examples are provided of locating points related by reflections across the x-axis and y-axis. Rules for reflections are stated. Students practice locating points based on given transformations including reflections. The lesson concludes with an exit ticket asking students about relationships between points related by sign changes in their coordinates.
