Solidify Understanding
Compares quadratic and linear functions, using all representations.
Model patterns with functions.
Compare and contrast linear and quadratic functions.
How are quadratic functions different than linear functions?
Lesson 3: Scott's Muscle March
Solidify Understanding

Model a quadratic function with tables, graphs, and equations.
Understand the first difference of a quadratic function.
How can a quadratic function be built from a linear function?
Lesson 4: Rabbit Run
Solidify Understanding

Lesson 5: The Tortoise and the Hare
Solidify Understanding
Compares quadratic and exponential functions in tables and graphs, with an emphasis on understanding that an exponential function will exceed any quadratic function for large values of x.
Compare quadratic and exponential functions.
Determine which type of function, quadratic or exponential, grows faster in a given interval.
How does the growth of a quadratic function compare to the growth of an exponential function?

Lesson 6: Be the Change
Practice Understanding
Builds fluency in distinguishing between linear, quadratic, and exponential relationships, using the rate of change.
Determine if a relation is linear, exponential, quadratic, or some other kind of function.
Determine the type of growth and key features of the function.
What characteristics of each representation make it easy to identify the function type?
