Instructional Ideas

• Use for an independent learning challenge; give learners the choice of watching the video or reading the lesson in print
• Create a guided notes handout for scholars to complete while watching the video

Classroom Considerations

• Classroom requires Internet access to view the video
• Continues a series of nine lessons related to functions

Pros

• Includes fractional outputs when creating tables for graphing
• The questions at the end of the problem set require higher-level thinking

Cons

• Input/output tables in the problem set provide input values, so pupils never determine their own input values
• Does not include problem solving or real-life situations
