This collection of resources includes videos, online practice problems and tests, and a card game involving solving absolute value equations and inequalities. Some of the resources in this collection will be inactive after June 24, 2014. Overall, this is a nice collection of resources that could easily be used in a classroom.
This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Calculating absolute value.
It explains how to find the absolute value of a function. It has several examples that will help you understand the concept of absolute value of functions. Overall, the mathematical formula for absolute value is:
|x| = x, if x ? 0
|x| = -x, if x < 0

In this experiment, students will predict, observe and compare the drop size (using diameter) of four liquids – alcohol, soap, water, and corn syrup. Students will be supplied with droppers, glass slides, a grid with which to measure, and four liquids.
This is a game where each student has one or more cards with an absolute value equation or inequality and the solution to such a problem. The first person begins with their problem and the entire group solves it to determine who has the solution on their card. They then give their problem. The students continue solving the problems until they return to answer on the original card.
