Unit 3. Purpose . Provided is a lesson for teachers to use to help students understand . how to construct and analyze function tables. Included are the following resources:. Common Core Standards. 6.EE.9 . Katherine Wu. the . absolute value. of a number is its distance from 0 on a number line. distance is nonnegative so the absolute value of a number is always positive. symbol |x| is used to represent the absolute number of a number x.
