Opening Activity: Simplify using with Like Terms – No calculator

3
Stand up/Hands up/Pair up Decide who is partner A and who is partner B. Partner A will go first – they will answer the question while Partner B listens Next Partner B will repeat what Partner A answer was.

4
Stand up/Hands up/Pair up Continued….. Partner A: What does it mean to simplify like terms Partner B: summarize what they said- including what their name is! Now partner B: answer the same question, then A summarizes

5
Stand up/Hands up/Pair up Continued….. Partner B: What would be a common mistake students make Partner A: summarize what they said- including what their name is! Now partner A: answer the same question, then B summarizes

6
Our First Vocabulary Word Like terms!!

7
Any questions??? Homework from last night – check answers! Now lets take LG#1 Quiz Now lets begin LG#2 – math can be confusing!!

9
Objective All students will begin to understand (level 2) how to solve a multi-step equation. Distributive Property Fractions Like terms

10
Algebraic Equations -20 10x = 60 10 4x +6x + 20 = 80 ( ) 10x + 20 = 80 10 x = 6

11
Algebraic Equations -12 5x = 80 5 3x + 2x + 20 - 8 = 92 5x + 12 = 92 5 x = 16 ( ) ( )

12
Algebraic Equations -12 2x + 12 = 122 2 6x + 15 = 125 + 4x 6x – 4x + 12 = 122 + 4x – 4x 2 2x = 110 ( ) X = 55

13
( ) 10x – 3x -12 = 4x – 9x + 48 Algebraic Equations Distributive Property 7x - 12 = -5x + 48 2(5x – 6) – 3x = 4(x + 12) – 9x 10x – 12 - 3x = 4x + 48 – 9x ( ) 7x + 5x - 12 = 48 12x - 12 = 48 ( )

14
12 7x + 5x - 12 = 48 12x - 12 = 48 +12 12x = 60 X = 5 Algebraic Equations Distributive Property

15
Important!!! How does this problem look different!!

16
The equal sign is the door…who goes out the door first? The work: The result:

17
Turn to your shoulder partner and discuss the differences between these two equations

18
Reflect on Objective All students will begin to understand (level 2) how to solve a multi-step equation. Are you ready to practice???

19
Little Harder What is a consecutive Integer? What is a consecutive odd integer? What is a consecutive even integer?? What are three consecutive integers that add up to 15? What are two consecutive odd integers that the sum is 20? Name two consecutive even integers that add up to -6.
