Instructional Ideas

• Create more problems or an instructional video so pupils needing extra practice can begin immediately rather than relying on whole class time

Classroom Considerations

• Resource best fits as a review before a big test; this allows teachers to quickly see what concept needs more practice while still allowing time to reteach as necessary
• Requires background knowledge in plotting points and graphing

Pros

• Provides a grading rubric to help with scoring
• Includes many sample answers and the proper analysis of the results

Cons

• None
