Through discussions and journaling, classmates determine methods to associate types of functions with data presented in a table. Small groups then work with examples and exercises to refine their methods and find functions that work to model given data sets.

Instructional Ideas

• Prior to working examples, have class members create tables of data that could be modeled by linear, quadratic, or exponential functions
• Create a matching activity with a set of tables and corresponding types of functions

Classroom Considerations

• The lesson assumes pupils recognize the shape of linear, quadratic, and exponential functions
• Use word processing programs to assist with journaling
• The second in a ten-module unit designed for the last unit in an Algebra I course

Pros

• Scaffolding suggestions are provided for the teacher throughout the lesson
• Exit ticket provided in order to assess understanding

Cons

• None
