Saxon Math: Algebra 2 (Section 7)

This Saxon Math: Algebra 2 (Section 7) unit also includes:

Section seven of twelve turns the mathematical eye toward higher-level concepts. From radians in the unit circle to the complex number system, logarithms to advanced factoring methods, this lesson—just past the halfway point in the series—definitely assumes that your classes have developed some serious mathematical chops along the way. However, this section does not neglect scaffolding, as evidenced by the many worked examples in each section, along with thorough explanations and diagrams. Sprinkle throughout the section some calculator labs and lessons on probability theory, and you have a recipe for an interesting few weeks in the algebra 2 classroom.

Instructional Ideas

  • Investigation 7 at the end of the section makes a great introduction to experimental design and sampling in an introductory statistics class or unit
  • Consider harvesting graphs, examples, and datasets from these lessons to supplement your own material. Of particular interest are the problem scenarios in the probability lessons and some of the diagrams in the unit circle and trigonometry lessons
  • Assign motivated learners to uncover the connections between the complex numbers, logarithms, unit circle, and trigonometry lessons presented in this section as separate concepts. This kind of project requires solid grounding in the irrational numbers, e in particular
Classroom Considerations

  • Lessons are largely modular, but be aware that the distributed practice problems at the end of each lesson includes material from previous sections
  • Calculator directions and activities assume that the class is using the TI-83/84/85 suite of graphing calculators
Pros

  • Detailed examples and graphics given for each lesson
  • Problems frequently reference real-life scenarios
  • Material broken down into small and easily processed chunks
Cons

  • No answer key provided
  • Lessons seem cobbled together in the section, without natural flow or progression
