This Instructional Activity is a part of the Lesson 12, Unit 2, Grade 6. Previously, students explored the limitation of a double number line when dealing with greatly scaled-up ratios, they saw that extending the number lines can be impractical. Here, they encounter a situation involving significantly scaled-down ratios, in which a double number line is likewise impractical (i.e., there is not enough room to fit relevant information) and see that a table is clearly preferable.
