This Problem Set is a part of the Lesson 14, Unit 1, Grade 6. Students associate with each ratio A:B the ordered pair (A, B) and plot it in the x-y coordinate plane. Students represent ratios in ratio tables, equations, and double number line diagrams and then represent those ratios in the coordinate plane. This lesson serves as a means for students to associate ratios with ordered pairs and plot the ordered pairs in the coordinate plane.
