Opening Activity:  Simplify using with Like Terms –  No calculator

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.

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

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

Our First Vocabulary Word  Like terms!!

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

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

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

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

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

( ) 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 ( )

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

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

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

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

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

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.
