Key Concepts

  • Distributive Property
  • Simplifying Expressions
  • Inverse Operations
  • Solving Equations

Learning Objectives

  • Students will be able to apply the distributive property to simplify algebraic expressions.
  • Students will be able to solve one-variable equations involving the distributive property.
  • Students will be able to check their solutions to ensure accuracy.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing what an equation is and the goal of solving an equation (isolating the variable). Briefly discuss the order of operations and how parentheses affect calculations. Show a simple example of an equation with parentheses.
  • Video Explanation (7 mins)
    Play the "Simplifying Equations using Distributive Property | Expressions & Equations | Grade 6" video by Math is Simple! Pause at key points to emphasize important steps like distributing, identifying inverse operations, and checking the answer. Encourage students to take notes.
  • Guided Practice (10 mins)
    Work through 2-3 example problems on the board, similar to those in the video. Clearly demonstrate each step: distribution, simplifying, isolating the variable using inverse operations, and checking the solution. Ask for student input at each step.
  • Independent Practice (10 mins)
    Provide students with 3-4 equations to solve independently. Circulate the classroom to offer assistance and answer questions. Encourage students to check their answers using the method demonstrated in the video.
  • Wrap-up and Review (3 mins)
    Review the key concepts of the lesson. Answer any remaining questions. Preview the next lesson or activity related to equations.

Interactive Exercises

  • Equation Challenge
    Divide the class into teams. Write an equation on the board, and have the teams race to solve it correctly. Award points for accuracy and speed.
  • Error Analysis
    Provide students with a worked-out problem that contains an error in the application of the distributive property or inverse operations. Have them identify and correct the mistake.

Discussion Questions

  • What does it mean to 'distribute'?
  • Why is it important to use inverse operations when solving equations?
  • How does checking your answer help you know if you solved the problem correctly?

Educational Standards

6.A.2.1:Generate equivalent expressions and evaluate expressions involving positive rational numbers by applying the commutative, associative, and distributive properties and order of operations to model and solve mathematical problems. 6.A.3.2:Use number sense and properties of operations and equality to model and solve mathematical problems involving equations in the form x + p = q and px = q, where p and q are nonnegative rational numbers. Graph the solution on a number line, interpret the solution in the original context, and assess the reasonableness of the solution.
