Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Inequality	5 minutes	Begin with a brief introduction of inequalities. Explain the symbols (<, >, ≤, ≥). Use examples.
2	Solving Linear Inequalities	10 minutes	Teach how to isolate the variable in a linear inequality. Provide step-by-step examples. Engage students with guided practice.
3	Graphing Inequalities	5 minutes	Demonstrate how to graph inequalities on a number line. Show examples and discuss open vs closed circles.
4	Real-Life Applications	5 minutes	Discuss a real-world scenario where inequalities are applicable (e.g., budgeting, weight limits). Ask students to suggest their own examples.
5	Practice Problems	5 minutes	Distribute worksheets with practice problems. Students work independently, then complete a few problems together as a class.
6	Homework and Conclusion	5 minutes	Assign homework focusing on inequalities. Provide instructions without asking students to present. Summarize key points of the lesson.

Homework

• Complete assigned worksheet on solving and graphing inequalities.
• Create three real-life scenarios involving inequalities and solve them.

Assessment

• Monitor student participation during the lesson.
• Review completed worksheets to assess understanding before the next lesson.

Notes

• Encourage students to ask questions throughout the lesson.
• Be mindful of students who may need additional support and provide differentiated assistance.
