ORELA Math: Graph Theory - Videos & Lessons

About This Chapter

This chapter includes a series of brief, entertaining videos that allow you to review the graph theory concepts you're expected to know for the ORELA Math certification exam. Let our instructors know if you have any questions as you work through the chapter.

ORELA Math: Graph Theory - Chapter Summary

These short videos are an enticing and convenient way to review the graph theory concepts you'll likely encounter on the ORELA Math certification assessment. This chapter covers the ideas you need to know, such as:

Basic graph theory and terminology
Euler's theorems, paths and circuits
The Fleury algorithm
The sum of degrees
Mathematical models
Hamilton paths and circuits
Complete and weighted graphs

The quick multiple-choice quiz after each lesson provides an important opportunity to test your understanding of graph theory and gain comfort with the material. If there are any areas you'd like to give additional review, use the video transcripts- they highlight key ideas, making them easy to locate.

Objectives of the ORELA Math: Graph Theory Chapter

The material in this chapter focuses on the graph theory concepts you're supposed to know for ORELA certification. Use the lesson quizzes to see the ORELA format--we mimic the assessment style so you can get practice for your exam.

Four and a quarter hours are permitted for ORELA Math test-takers. The computer-administered assessment includes approximately 150 multiple-choice questions that assess competency in five content areas: measurement and geometry; statistics, probability and discrete math; trigonometry and calculus; math processes and number sense; and patterns, algebra and functions. The first four make up 19% of the exam each, and the final (patterns, algebra and functions) makes up the remaining 24%.
