By the end of this lesson, students will be able to:

1. Understand the concept of variables and constants.
2. Identify and use algebraic expressions.
3. Solve simple equations.

---

Materials Needed

• Whiteboard and markers
• Graphing paper
• Algebra textbooks
• Worksheets for practice problems
• Pencils and erasers

---

Standards Alignment

This lesson aligns with the Common Core State Standards for Mathematics, specifically:

• CCSS.MATH.CONTENT.7.EE.A.1: Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
• CCSS.MATH.CONTENT.7.EE.B.4: Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

Lesson Outline

Introduction (5 minutes)

• Start with a question: “What do you think a variable is?”
• Briefly discuss students' thoughts and introduce the concept of variables as symbols that represent numbers.
• Explain constants as fixed values.

Direct Instruction (10 minutes)

• Define Algebraic Expressions:

  • Provide examples of expressions (e.g., 3x + 4, 5y - 2).
  • Explain the difference between terms, coefficients, and constants.

• Simple Equations:

  • Introduce balanced equations. For example, explain that 2x + 3 = 11 can be solved by isolating the variable x.
  • Show step-by-step how to solve a basic equation.

Guided Practice (10 minutes)

1. Example Problem: Solve the equation 4x - 5 = 11.
   • Work through it as a class:
     • Add 5 to both sides.
     • Divide by 4.
2. Student Exercises:
   • Distribute worksheets with similar problems.
   • Allow students to work individually or in pairs.

Independent Practice (5 minutes)

• Assign students a set of problems from the textbook to complete as homework, focusing on solving equations and simplifying expressions.
• Encourage them to create one equation of their own and solve it.

---

Conclusion (5 minutes)

• Recap key concepts discussed in the lesson.
• Ask students: “What do you now understand about algebraic expressions and equations?”
• Address any remaining questions.
• Assign homework to reinforce concepts learned today.

---

Assessment

• Students will be assessed based on their participation in class discussions, their accuracy in guided practice problems, and their completed homework assignments.

---

Reflection

• After the lesson, reflect on students' understanding and any challenges faced during the lesson.
• Adjust future lessons based on student performance and comprehension levels.
