Use a straightforward approach to understanding logarithmic properties and their role in solving exponential and logarithmic equations to your math class. The lesson begins with an overview of a logarithmic function and its connection to an exponential function. After discussing properties of logarithms, the practice activity utilizes the properties to solve exponential and logarithmic equations.

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

Pros

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

Cons

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