Objectives of the WEST Math: Inequalities Chapter

The WEST certification assessment for math educators is a four hour and fifteen minute, computer-administered test of 150 questions spanning five content domains: mathematical processes and number sense questions (accounting for 19% of your score); patterns, algebra and functions (24%); measurement and geometry (19%); trigonometry and calculus (19%); and statistics, probability and discrete mathematics (19%).

Use the engaging videos in this chapter to study the important inequalities concepts you need to know for the assessment. As you work through the lesson quizzes, you'll gain practice using the material, but you'll also get the opportunity to practice answering questions in the WEST format.
