Instructional Ideas

  • Arrange classroom to facilitate small group discussions
Classroom Considerations

  • Calculators will help in evaluating complicated exponential expression
  • The second lesson on relationships between numerical variables, and the 13th lesson of a 20-lesson module
  • Not all scatter plots are readable in the PDF; Doc versions have readable scatter plots
Pros

  • Builds on previous learning on linear and nonlinear scatter plots
  • Provides guidance to teacher on whether to work as collaborative groups or individuals
Cons

  • None
