## Algebra 2B

### Course Description

Uses the ASKME® model to introduce functions, with a focus on multiple representations. Continues study of the fundamentals of algebraic operations equations of first degree, graphs, ratios and proportions. This course is entirely online. (Prerequisite: Algebra 2A)

### Required Course Materials

TI-83 graphing calculator

### Course Organization

Chapter Movies. These animations will show you a problem that you will learn about throughout the unit.
Activities. The Activities are practice assignments. Each Activity is a non-graded exercise that allows you to build your knowledge and identify your strengths and weaknesses. Generally, the Activities consist of:
Introduction: A short introduction to the Activity.
Review Exercises: Short review assignments that you submit for a grade. These are required and must be completed to finish the course.
Tutorials: Animations that teach concepts and ideas.
Guided Practice Questions: Questions to answer with the help of hints.

### Final Examination

The final examination is comprehensive; it covers the material from all of the units. To pass the course, you must receive a grade of 70 percent or better. You can apply to take the Final Exam after 100 percent of your graded assignments have been submitted, and at least 70 percent have been graded and returned to you.
Time Allowed: 3 hours
