Published on 02/10/2004

Activity Overview

This StudyCards™ set uses guided discovery concepts to develop ideas for functions operations, building from rational expression multiplication and division algorithms. Use with Foundations for College Mathematics, ch. 7.3.

Before the Activity

Students should have access to either the TI-83 Plus or TI-84 Plus family of calculators. Download the attached StudyCard file to students' calculators.

During the Activity

Rational expression multiplication and division algorithms are based in arithmetic, but then progress to function operations. Use this StudyCards set to learn go through guided discovery concepts to develop ideas for the operations. Confirm products or quotients by comparing numeric representations of the problem and 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
