Rational Reduction

Activity Overview

This StudyCards™ stack begins with arithmetic examples and continues through algebra. Students compare numeric representations of the problem to confirm the correct reduced form. Use with Foundations for College Mathematics, Ch. 7.2.

Before the Activity

Understand behaviors of functions, particularly the connection between the symbolic form and the graphical form of basic functions.

During the Activity

Use this StudyCards™ set for a discovery activity that starts with arithmetic examples and continues through algebra. Confirm correct reduced forms through comparing numeric representations with your answers. A discussion of domain is included.

After the Activity

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
