Teacher Resources for Instructional Planning


Precalculus Std 6: Apply the laws of logarithms to simplify expressions and to solve equations using common logarithms, natural logarithms, and logarithms with other bases.

Lesson Plans Music to Math: Exploring the Relationships between Frequencies of Musical Tones This lesson dealing with the frequency of musical tones is more accurately related to exponential functions. The CBL is required. Chicago Public Schools The properties of logarithms are developed and illustrated. Some real-world connections are made. Compound Your Way to a Million Bucks! This lengthy lesson deals with the compound interest problem in a real world setting. Rhinos and M&M’s® (Exponential Models) This lesson from PBS is really an exponential model. It creates an exponential model using M&M's. It is also appropriate for lower grades. There is an accompanying online video. Sonic Booms and Logarithms This lesson analyzes sonic booms using the decibel formula. It provides a number of interesting links. Modeling Exponential Growth In this online lesson, students solve typical exponential problems such as those that model exponential growth and decay. Can Cruddy Cool As Fast As Clean? Students will investigate variations in cooling times for ordinary tap water and salt water. Data will be collected using the CBL unit and the TI-82 calculator to create and interpret data plots. Students will become familiar with Newton’s Law of Cooling and be able to verbalize and write conclusions made from the collected data. Chicago Public Schools The lesson for days 105 and 106 provide techniques, practice, and applications for solving equations involving natural logarithms. Credit Cards: The Fine Print This PBS lesson plan requires that you get a video to go with the lesson plan. It explores credit card terminology and balances over time.
