- Greater than, less than, greater than or equal to, less than or equal to
- Inequality symbols
Procedure
Introduction
As a hook, ask students why it is important to learn how to solve and graph two-step inequalities. You can refer to the real-life application provided on the last page of the guided notes, such as instances where inequalities can be used in determining the number of hours needed to complete a task or the temperature range for a specific event. You can also refer to the FAQs section for more ideas on engaging questions.
Use the first page of the guided notes to introduce the topic of solving two-step inequalities. Walk through the key points of the topic, including the types of inequality symbols, how to isolate the variable and perform arithmetic operations to solve for the variable. Emphasize the importance of using inverse operations when solving.
Continue with page 2 of the guided notes, following the same format of introducing how to graph inequalities on number lines (including open and closed circles). Students will first take notes on the key points, and then they can start the practice examples on the page.
Based on student responses and understanding, reteach concepts that students need extra help with. If there is a wide range of proficiency levels in the class, consider pulling out students for reteaching while more advanced students begin working on the practice exercises.
Practice
Have students practice solving and graphing two-step inequalities using the practice worksheet provided in the resource. They can complete the maze (page 3 of the guided notes) and color by number problem sets (page 4 of the guided notes) to reinforce their understanding of the math concept.
Walk around the classroom to answer any student questions and provide assistance as needed. You can also assign any of the practice activities as homework for the remainder of the class to provide additional practice and reinforcement.
Real-Life Application
Use the last page of the guided notes resource to bring the class back together, and introduce the concept of real-world applications of solving and graphing two step inequalities. Discuss with the students how inequalities can be used to represent real-life situations where there are limitations or constraints.
For example, you can explain how two step inequalities can be used to represent situations such as budgeting. Discuss scenarios where a person has a limited amount of money to spend and needs to decide how much they can spend on different items. Explain that they can use two step inequalities to set limits on their spending based on their available funds.

FAQs
Two-step inequalities are mathematical expressions that involve two operations to solve. They involve inequalities (such as greater than or less than symbols) and require multiple steps to find the solution.
To solve a two-step inequality, follow these steps:
- Perform the inverse operation on both sides of the inequality to isolate the variable.
- Simplify both sides of the inequality.
- Determine the solution by writing the solution set or graphing the solution on a number line.
Solving a two-step inequality involves finding the range of values that make the inequality true. This is typically done algebraically by isolating the variable. Graphing a two-step inequality involves representing the solution as a shaded region on a number line or coordinate plane.
To represent the solutions of two-step inequalities graphically, follow these steps:
- Draw a number line or coordinate plane.
- Find the solution to the inequality algebraically.
- Shade the region of the number line or coordinate plane that represents the solution.
Guided notes in this lesson plan provide a structured outline for students to follow during instruction. They help students stay engaged and organized by providing an outline of the main concepts, examples, and check-ins for understanding.
Doodle sketch notes engage students in learning by combining visual and textual elements. They allow students to personalize their notes by adding drawings, color-coding, and other creative elements. This multisensory approach can enhance comprehension and retention of the material.
You can use this resource for spiral review by assigning the practice worksheets or maze as homework or as a warm-up activity in future lessons. This allows students to continually practice and reinforce their understanding of two-step inequalities over time.
