"Demystifying e" Day #1

Unit 2: Exponential and Logarithmic Functions
Lesson 15 of 21

Objective: This lesson serves as the foundational lesson for the next several days. It provides the connection between the important mathematical constant 2.718… and exponential functions. e is both derived and defined through investigation in the lesson where students seemly “stumble upon” its overarching idea. More than many other lesson, it is extremely important that this lesson is teacher DRIVEN and student MOTIVATED. Due to the nature of the content, and the students relative inexperience with high level mathematical conversations – the teacher must be careful to steer the lesson in the intended direction. The PowerPoint and student notes guide are powerful tools for making sure this happens! Despite the lesson being teacher driven, it must also be STUDENT motivated. Through the scaffolding activities and analogies provided, the students will be engaged in deep conversations throughout much of the period.

Big Idea: This lesson mixes the ingredients of lecture, investigation, application, and a touch of creativity to “Demystify e”!
