## Reflection: Modeling Ferris Wheel Speeds - Section 3: Describe Speed Relationships

When it comes to describing relationships, an important learning goal for my students is to learn to use multiple representations effectively. Some students will describe relationships verbally. Others more concretely, perhaps with data tables or some explanation of the behavior of the data table. Other students will try to figure out what kind of functions fit these relationships. The most abstract understanding possible is for students to actually write function rules to describe these relationships.

# Ferris Wheel Speeds

Unit 9: Ferris Wheels
Lesson 5 of 11

## Big Idea: How fast is the rider actually moving as the wheel turns? How do changing the angular speed and the radius of the wheel affect the speed of the rider? Students make a generalization about how these changes affect the rider's speed.
