This Instructional Activity is a part of the Lesson 10, Unit 7, Grade 8. It prompts students to use the structure of the number line to compare numbers, and to extend their use to estimate relative sizes of other numbers when no number lines are given. As students work, notice the ways in which they compare expressions that are not written as multiples of 10^6. Highlight some of these methods in the discussion.
