Instructional Ideas

• Provide the class with additional exercises to use as practice
• Have pupils determine which method of finding the slope is the easiest for them

Classroom Considerations

• The lesson hinges on doing the opening activity before beginning the instruction

Pros

• The plan contains warm-up problems that connect previous learning to the current learning
• The teacher pages have suggestions for what the instructor should say during the instruction

Cons

• The independent problems are not included in the handout
