Lesson Plan: SAT Math Lesson 21: Polynomials and Their Graphs

In SAT Math Lesson 21, students will explore the key characteristics of polynomials and how to analyze and graph them. This lesson covers:

• Identifying the degree and leading coefficient of a polynomial,
• Factoring polynomials to find roots (or zeros),
• Analyzing end behavior based on degree and leading coefficient, and
• Interpreting and sketching graphs of polynomial functions.

The lesson provides step-by-step instruction using worked examples and visual aids to help students understand polynomial structure and graph behavior. Students will practice identifying roots, turning points, and end behavior, all of which are commonly tested on the SAT Math section. This foundational knowledge equips students to confidently tackle polynomial-based algebra questions on the test.
