This Light It Up lesson plan also includes:
A new laser-pointing game exists at the Springfield fair, and Lisa thinks there is a mathematical formula to help her win! Pupils investigate rational functions using graphs. Groups experiment with a mirror and laser pointer, so a reflected light image hits the wall and collects distance data. They develop rational functions and determine the information needed to help win the game.
- After the lesson, brainstorm other real-world situations that would be modeled by a rational function
- Requires a laser pointer or flashlight along with a flat mirror and tape measure for each group
- The class should be comfortable with plotting points from a table
- Provides a suggestion for an extension activity
- Includes teacher reflection questions on how well the lesson went
- Contains solutions to activity questions
