What Your Child Will Learn
- 1
Understanding Inequalities
Learn what inequality symbols mean and how inequalities differ from equations.
Objective: Students will interpret and use inequality symbols (<, >, <=, >=) to compare quantities and understand how inequalities differ from equations.45 minutes - 2
Graphing Inequalities
Learn to represent inequalities on a number line using open and closed circles with directional shading.
Objective: Students will graph inequalities on a number line using open circles for strict inequalities and closed circles for inclusive inequalities, with correct directional shading.45 minutes - 3
Solving One-Step Inequalities
Apply equation-solving strategies to one-step inequalities using inverse operations.
Objective: Students will solve one-step inequalities using inverse operations (addition, subtraction, multiplication, division) and graph the solutions.45 minutes - 4
Solving Two-Step Inequalities
Extend one-step strategies to solve inequalities requiring two operations.
Objective: Students will solve two-step inequalities by applying inverse operations in the correct order (addition/subtraction first, then multiplication/division).45 minutes - 5
Multiplying and Dividing by Negatives
Discover why we must flip the inequality sign when multiplying or dividing by a negative number.
Objective: Students will correctly solve inequalities that require multiplying or dividing by negative numbers, understanding why the inequality sign must be flipped.45 minutes - 6
Writing Inequalities
Translate verbal descriptions and word problems into algebraic inequalities.
Objective: Students will translate verbal phrases and word problem situations into algebraic inequalities using appropriate symbols and variables.45 minutes - 7
Compound Inequalities
Understand and solve compound inequalities using AND and OR to combine conditions.
Objective: Students will solve and graph compound inequalities using AND (intersection) and OR (union) to combine two conditions.45 minutes - 8
