Reflection: Intrinsic Motivation A Penny or $100,000! - Section 1: Introduction

 

This lesson was fun for students and for me.  Watching them think that they would take the $100,000, but then wondering if it was a trick or not.

This suspicion made the students drive forward to find a solution.  Students were writing out the entire table of values instead of deriving a formula from the table.  It takes a little more time than I had originally thought, but it is worth it.  To see them finally solve the problem and then realize the doubling the pennies every day was a better deal.

The Math Dude shows enthusiasm to set up the problem well, and when I pause it at the end of the question, students begin to think and work.  Students then want me to show the remainder of the video to verify the solution.

A Penny or $100,000!

Unit 6: Exponential Functions
Lesson 1 of 13

Objective: SWBAT identify, graph, and explain exponential growth for functions of the form f(x)=ab^x where b > 1, and f(x)= a( 1 + r)^t using a table of values.

Big Idea: Students compare the pattern of change of an exponential function to the rate of change in a linear function.
