Exponentials and Logarithms: LOUD and CLEAR!

Unit 2: Exponential and Logarithmic Functions
Lesson 9 of 21

Objective: This lesson will allow the students the opportunity to investigate a real life application of logarithms. Students will be asked to present a portion of their findings to the class on the following day. A brief scaffolding workshop on engaging oral communication might be appropriate, and can be found as an optional addition to this lesson plan. It is important to teach students to communicate mathematics confidently, and in a way that is audience appropriate. Look for sample student presentations when I reflect on this activity in the future! These videos could also make great teaching tools for your students.

Big Idea: This engaging lesson allows the students to apply logarithms to the real world! After finishing the study, students will think twice before playing their music too loud!
