This 20-slide PowerPoint presentation tests and develops three rules involving reflections resulting from sign changes in an ordered pair. The three rules involve changing the x-coordinate sign only, changing the y-coordinate sign only, and changing both coordinate's signs. Thus the result is reflection across the y-axis, reflection across the x-axis, and reflection across the origin, respectively. Students are expected to have previous knowledge of plotting & identifying ordered pairs, identifying & numbering quadrants, and identifying the signage patterns of ordered pairs in each quadrant. The content is based on Common Core standard CCSS.Math.Content.6.NS.C.6b under the domain The Number System. The presentation can be covered in about 20 to 30 minutes depending on how much student involvement you plan to institute. You can also use the presentation for individuals needing remediation or who might have missed the lesson.
