Lesson Plan: Algebraic Equations for Ages 1112
Objective: By the end of the lesson, students will be able to solve algebraic equations with one variable, and apply their knowledge to reallife situations.
Materials:  Whiteboard or blackboard  Markers or chalk  Algebraic equation worksheets  Reallife situation question handouts  Pencils and erasers
Procedure:

Introduction (5 minutes)  Begin the lesson by asking students if they have ever seen or heard of algebraic equations before.  Explain that algebraic equations are mathematical expressions that use letters to represent unknown values.  Give examples of simple algebraic equations, such as β2x = 10β or β3y + 5 = 20β.

Explanation of Variables (10 minutes)  Write a simple algebraic equation on the board, such as β3x = 15β.  Explain that the letter βxβ in the equation represents an unknown value that we need to find.  Discuss how the equation is balanced, with the same value on both sides of the equal sign.  Emphasize that the goal is to isolate the variable and find its value.

Solving Algebraic Equations (15 minutes)  Provide stepbystep instructions for solving algebraic equations with one variable: a. Identify the variable and its coefficient. b. Use inverse operations to isolate the variable on one side of the equation. c. Simplify both sides of the equation until the variable is alone. d. Solve for the variable by performing the necessary operations.  Demonstrate the process by solving a simple equation together as a class.

Practice Questions (20 minutes)  Distribute algebraic equation worksheets to each student.  Instruct students to solve the equations independently, using the steps discussed earlier.  Circulate the classroom to provide assistance and guidance as needed.  After completing the worksheets, review the answers as a class, discussing any common mistakes or misconceptions.

RealLife Situation Questions (15 minutes)  Distribute reallife situation question handouts to each student.  Explain that these questions will require students to apply their knowledge of algebraic equations to solve practical problems.  Instruct students to read each question carefully and write down the equation that represents the given situation.  Allow students to work on the questions independently, and provide assistance as needed.  Review the answers as a class, discussing the process of translating reallife situations into algebraic equations.

Conclusion (5 minutes)  Summarize the key points covered in the lesson, emphasizing the steps for solving algebraic equations.  Encourage students to practice solving equations on their own to reinforce their understanding.  Answer any remaining questions and provide additional resources for further practice if desired.
Assessment:  Monitor studentsβ progress during the practice questions and reallife situation questions.  Review their completed worksheets and question handouts to assess their understanding of algebraic equations.  Provide feedback and address any misconceptions or areas of improvement.
