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)

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

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
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
