SAT Math Lesson Plan2: Linear Inequalities

Understanding linear inequalities is essential for mastering SAT Math, especially within the Heart of Algebra domain, which makes up approximately 35% of the SAT Math section. This 45-minute lesson focuses on solving and graphing linear inequalities in one and two variables. Students will learn how to manipulate inequalities algebraically, including what happens when multiplying or dividing by negative numbers, and how to graph solution sets on the number line and coordinate plane.

Through five fully worked-out examples, students will explore key strategies for interpreting inequality symbols, testing solutions, and shading solution regions. One example demonstrates a real-world scenario involving budgeting, showing how linear inequalities can model everyday decision-making. This lesson is ideal for both classroom instruction and independent study, with clear explanations, visual guidance, and self-study tips throughout. Students can assess their understanding with a 10-question multiple-choice quiz and a detailed answer key with step-by-step solutions.
