Instructional Ideas

  • Use practice problems for guided instruction; as your class becomes more comfortable with logarithmic properties, progress to independent practice
  • Consider using board work with the practice problems to help determine understanding and misconceptions
Classroom Considerations

  • Does not provide practice with properties before solving equations; may need to be supplemented

  • Provides an answer key with the practice problems
  • "Think" statements are helpful in determining how to present the material

  • Requires supplemental problems if properties are to be practiced before solving equations
