  • Use the PREMDAS chart to solve this equation… don’t forget that fractions are another form of division!
  • Have students come up and show their work by writing on the whiteboard
  • If this picture looks like it’s moving to you, your brain is definitely ready for the next level! LOL
  • Now put this example on the board - t (2x + 3) = 12x + b (use triangle and box)
  • Transcript

    • 1. Unit 4 Lesson 4Objective: Today our goal is to use multiple properties to solveequations and solve for missing values using the Distributive andCommutative Property
    • 2. Let’s review our vocabulary:• Variable – A letter or symbol that represents a number• Term-• Coefficient• Constant• Pattern• Distributive property• Commutative property• Expression
    • 3. Let’s review the Order of Operations ONE MORE TIME! Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 4. 4.4
    • 5. Distributive Property http://prezi.com/mqus64kvbhf2/distributive- and-commutative-property/ Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 6. 7(9+2)=63+14 or 7(11) Is it okay to do this? 7(9+2)=14+63 Turn and Talk! Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 7. If we get the same answer then it’s totally okay! It is because of a certain property that we can move the numbers around when multiplying or adding while using the Distributive Property and it will still give us the same answer! Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 8. Let’s look at another equation! First let’s solve them then state the property that was used! 8(3-2)= 24 – 16  Distributive Property Answer: 8  Distributive Property 8(3-2)= 8(1) Answer: 8  The Distributive Property 8(3-2)= -16 + 24 including the use of the Commutative Property Answer: 8 Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 9. Now you try! Use the commutative property to write the equation that uses the distributive property in a different way! 7(9 + 4) = 63 + 28 7(9+4) = 28 + 63 8(7-2) = 56 - 16 8(7-2)= -16 + 56 -4(9+3) = -36 +(-12) -4(9+3)= -12 + (-36) Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 10. Are these two equations the same? 7(5-3)= 35-21 7(5-3)= -21+35 14 14 Yes, they are because the commutative property allows you to multiply or add numbers in any order and get the same answer! Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 11. Let’s take it one step further…
    • 12. a(8+2)= 16 + 4,What’s the value of a? 4
    • 13. a(8+2)= 16 + 4,Awe that’s easy, it’s… it’s… it’s… well that’s some question you got there Frank!
    • 14. a(8+2)= 16 + 4 What times 8 will give me +16 and what times 2 will give me +4? 2 Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 15. Now you try one! j(6+4)=18 + 12 j=3 Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 16. Man, now this is critical thinking! Distributive Property g(3 +4)= 9 + g(3a +4)= 9a + a=3 g(3a +4)= 9a+ b b=12 3(3a +4)= 9a + 12 Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 17. Let’s wrap this all up!You and your partner You and your partneruse a whiteboard to solve for thewrite this equation following variablesusing thecommutativeproperty h(2x - 4) = -4h + i7(3+2)= 21 + 14
    • 18. That’s all folks!Now let’s do some independent practice!
    • 19. In-Class assignment… • Work independently to complete the in-class work on Evaluating Expressions • Your teacher will monitor your progress while you work • When you finish, please work on Math Minutes, Complete corrected homework, or Read your choice book • Do Not raise your hand. Look at your notes for help or skip the question and work on a different question until your teacher comes to your desk. Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
    • 20. Exit Ticket • What is something that I learned in today’s lesson that I didn’t know how to do that I now know how to do? • I wonder… Objective: Today our goal is to use multiple properties to solve equations and solve for missing values using the Distributive and Commutative Property
