  • Graphing and solving quadratic inequalities and systems

Review the video transcripts for a second look at the ideas; key terms and concepts are highlighted. Take the lesson quizzes to evaluate your exam-readiness and gain confidence with the material. If you have any questions, please ask our instructors for guidance.

Objectives of the ORELA Math: Inequalities Chapter

If you're nervous about your upcoming ORELA Math certification assessment, use this chapter to master the inequalities concepts you'll likely be tested on and to introduce yourself to the ORELA format- our quizzes mimic the multiple-choice exam style and allow you to get an idea of how quickly you can work through the questions.

The four-and-a-quarter hour, computer-administered exam includes 150 questions covering five content domains. Math processes and number sense; patterns, algebra and functions; measurement and geometry; and stats, probability and discrete mathematics each account for 19% of your score. The remaining 24% of the exam is devoted to questions about patterns, algebra and number sense, where questions on inequalities may appear.
