Instructional Ideas

• Use a graphic organizer to record examples from the video

Classroom Considerations

• Learners should be familiar with calculating x- and y-intercepts and components of a circle
• Use after introducing the standard circle equations

• This video is hosted on YouTube

Pros

• Shows each step in solving individual problems
• Demonstrates six different examples that involve using the circle equation

Cons

• Refrains from using application problems or those with context
