Day 115

You need:

  • your device
  • a pencil
  • a pen
  • your homework
  • your Notebook

Agenda

  1. Warm Up: Which One Doesn't Belong 
  2. Correct Homework: WS Solving Linear Equations
  3. Solving Equations: Using the Addition Property or the Multiplication Property
    1. Finish Task 2 and glue it into your notebook. Remember to add it to your Table of Contents.
    2. Task 3 through 6: Solve each problem in your Notebook




Task 3: An Equation With Decimals

  • Use either the addition or multiplication property of equality to solve this equation: 8.05=x+4.9
  • Write the name of the property, and show each step you used to find the solution.
  • Check your solution by substituting it for x in the equation. Does your solution make the equation true?

Task 4: An Equation With Whole Numbers

  • Use either the addition or multiplication property of equality to solve this equation: 7y=329
  • Write the name of the property, and show each step you used to find the solution.
  • Check your solution by substituting it for y in the equation. Does your solution make the equation true?

Task 5: An Equation With a Fraction

  • Use either the addition or multiplication property of equality to solve this equation: 
  • Write the name of the property, and show each step you used to find the solution.
  • Check your solution by substituting it for m in the equation. Does your solution make the equation true?

Task 6: A Proportional Equation

  • Use either the addition or multiplication property of equality to solve this equation: 
  • Write the name of the property, and show each step you used to find the solution.
  • Check your solution by substituting it for p in the equation. Does your solution make the equation true?

Step 1: Work Time

Task 7: Prepare a Presentation on a Google Slide

Choose one of the equations you have solved to present.
  • Show the steps you took to solve the equation.
  • Explain how you used one of the properties of equality to solve.
  • Include a screenshot of your work or take a picture of your work and upload it
  • Add your slide to the class slide show linked here.




Step 2: Work Time

Challenge Problem

  • How could you use the addition and multiplication properties of equality to solve the equation 5x+2=2x+9 ?






Performance Task

Ways of Thinking: Make Connections
  • Take notes about the properties and steps your classmates used to solve the equations.

Task 9: Summary of the Math: Properties of Equality
Read and Discuss

  • Addition property of equality : If a=b, then a+c=b+c.
  • Multiplication property of equality : If a=b, then ac=bc.
  • These two properties of equality are very useful. For any equation that is true, you can
    • Add the same value to both sides or subtract the same value from both sides and the equation will still be true.
    • Multiply or divide both sides by the same value and the equation will still be true.


Can you:
  • Provide examples of equations that can be solved using the addition property of equality, and explain the steps for using the property to solve each equation?
  • Provide examples of equations that can be solved using the multiplication property of equality, and explain the steps for using the property to solve each equation


Work Time
