1 Name Working with Absolute Value - Step-by-Step Lesson Lesson 1 Absolute Value Problem: 1. Find the absolute value. 6 = Explanation: Absolute values focus on the size or magnitude of a number. They do not leave any regard for the sign of the number, as a result absolute values are positive or zero. The absolute value of a number is its distance from Again it does not matter if the number is negative or positive. On a number line, 6 is 6 units to the right of 0. So the absolute value is 6. As you can see above, -6 and 6 have the same absolute value since they are 6 units from 0.

2 Name Working with Absolute Value - Guided Lesson Complete the following problems: 1) Find the absolute value. (a) 4 = (b) -27 = (c) -18 = 2) Simplify each equation below. (a) = (b) = (c) = 3) Simplify each equation below. (a) -8-4 = (b) = (c) =

3 Name Working with Absolute Value - Guided Lesson Explanation Explanation#1 a) Step 1) Absolute values are positive or zero. Step 2) The absolute value of a number is its distance from 0. On a number line, 4 is 4 units to the right of 0. 4 is the absolute value of 4. b) Step 1) Absolute values are positive or zero. Step 2) The absolute value of a number is its distance from 0. On a number line, -27 is 27 units to the left of is the absolute value of -27. c) Step 1) Absolute values are positive or zero. Step 2) The absolute value of a number is its distance from 0. On a number line, -18 is 18 units to the left of is the absolute value of -18. Explanation#2 a) Step 1) Absolute values are positive or zero. Step 2) The number inside the sign when comes out, becomes positive = = -2 Answer is -2 b) Step 1) Absolute values are positive or zero. Step 2) The number inside the sign when comes out, becomes positive = 8-4 = 4

4 Name Answer is 4 c) Step 1) Absolute values are positive or zero. Step 2) The number inside the sign when comes out, becomes positive = -4-9 = -13 Answer is -13 Explanation#3 Step 1a) Absolute values are positive or zero. Step 2a) The number inside the sign when comes out, becomes positive = -4 Answer is -4. b) Step 1) Absolute values are positive or zero. Step 2) The number inside the sign when comes out, becomes positive = -8 Answer is -8. c) Step 1) Absolute values are positive or zero. Step 2) The number inside the sign when comes out, becomes positive = 5-3 = 2 Answer is 2.
