Lesson Plan: Introduction to Rational Expressions

In this lesson, students will explore the fundamentals of rational expressions, a key concept in algebra. They will learn how to identify, simplify, and evaluate rational expressions by applying their understanding of fractions and algebraic operations. This lesson introduces students to the structure of rational expressions, emphasizing their similarities to numerical fractions and their role in algebraic problem-solving.

Key concepts covered in this lesson include:

• Understanding the definition and structure of rational expressions.
• Identifying rational expressions and distinguishing them from other algebraic expressions.
• Simplifying rational expressions by factoring and reducing common terms.
• Evaluating rational expressions for given variable values.
• Recognizing restrictions on the variable that make the expression undefined.

Through guided instruction and practice exercises, students will strengthen their algebraic reasoning and develop a solid foundation for working with rational expressions in more advanced mathematical topics. This lesson provides a step-by-step approach to understanding and simplifying these expressions, preparing students for future lessons on operations with rational expressions.
