Grade 6 — Understand the absolute value of a rational number as its distance from 0 on the number line.

The skill that covers it

Absolute Value & Compound InequalitiesSolve equations with an absolute value by splitting them into two cases, and solve compound inequalities joined by "and" or "or", writing each solution as an interval on the number line.Read the lesson →

What a student should be able to do

Solve |x - a| $= b$ and |ax $+$ b| $= c$ , giving both solutions.
Solve an "and" compound inequality such as $-3 < 2x + 1 <= 7$ .
Solve an "or" compound inequality and describe its solution set.
Solve an absolute value inequality and write the solution as a compound inequality.
