This Instructional Activity is a part of the Lesson 14, Unit 7, Grade 6. The purpose of this task is for students to connect opposite signs in coordinates with reflections across one or both axes. Students investigate relationships between several pairs of points in order to make this connection more generally. The square grid, spaced in units, means that students can use counting squares as a strategy for finding distances. The use of the word "reflection" is used informally to describe the effect of opposite signs in coordinates.
