This Instructional Activity is a part of the Lesson 11, Unit 2, Grade 6. Here, students are asked to find missing values for significantly scaled-up ratios. The activity serves several purposes: To uncover a limitation of a double number line (i.e., that it is not always practical to extend it to find significantly scaled-up equivalent ratios), To reinforce the multiplicative reasoning needed to find equivalent ratios (especially in cases when drawing diagrams or skip counting is inefficient), and To introduce a table as a way to represent equivalent ratios.
