Distances on the Number Line 2

Illustrative MathematicsVaries

The purpose of this task is meant to reinforce students' understanding of rational numbers as points on the number line and to provide them with a visual way of understanding that the sum of a number and its additive inverse (usually called its 'opposite') is zero. Students should have lots of opportunities to represent adding specific rational numbers before they work on answering this one.
