Exponentials Lesson 3

Creating an Equation

The students use their timeline to find expressions for the height of the beanstalk on several days. They use similar reasoning to create an equation that gives the height of the beanstalk on any day.

Episode 1: Making Sense

The students revisit the timeline they made in the last lesson and mark in several important mathematical relationships among the heights and among the days.

Episode 2: Exploring

Arobindo and Josh use their timeline to create an expression that represents the height of the beanstalk on Day 25.

Episode 3: Repeating Your Reasoning 

Josh and Arobindo use their timeline to create an expression that represents the height of the beanstalk on Day 100.

Episode 4: Reflecting

The students use their timeline to create an equation that gives the height of the beanstalk on any day.
