Differences and Distances

Illustrative MathematicsVaries

The purpose of this task is to help students connect the distance between points on a number line with the difference between the numbers. Students should already understand that this is true for positive numbers. Students should also have experience in earlier grades representing signed numbers on a number line. This task assumes that students are familiar with the idea that differences between integers correspond to distances between them on the number line and asks them to analyze a situation involving non-integer quantities.
