Welcome To Mr. Mealey’s MATH III
I need your attention • When I do this • You do this
I am a problem solver Not a problem maker I am an answer giver not an answer taker I can do problems I haven’t seen I know that strict doesn’t equal mean In this room we do our best Taking notes -practice –quiz- test The more I try the better I feel My favorite teacher is Mr. Meal…..ey
What to expect this year • To become a better problem solver • To be challenged to do your best • to be supported by me doing my best
A little bit about me….. To do To don’t Tolerate an environment detrimental to learning Know what todays date is Allow you to deny the obvious(Lie) • Present material in various forms early and often • Teach you how to solve problems you have never seen before • Speak less than 20 minutes in a row • Challenge you to do your best • Do my best supporing you
Ex. 1: Solve 4x – 5 = 15 4x – 5 = 15 +5 +5 (Add 5 to both sides) 4x = 20 (Simplify) 4 4 (Divide both sides by 4) x = 5 (Simplify)
Ex. 1: Solve 2x – 9 = 17 2x – 9 = 17 +9 +9 (Add 9 to both sides) 2x = 26 (Simplify) 2 2 (Divide both sides by 2) x = 13 (Simplify)
Try These Examples • 3y + 7 = 25 • 5n – 2 = 38 • 12b + 4 = 28
Check your answers!!! • y = 6 • n = 8 • b = 2
Some more about MeJobs I have had • Paperboy • Dishwasher • Telemarketer • Birthday cookie deliverer • Beach photo guy • Arcade change guy • Vacuum cleaner salesman • Pizza maker/prep cook • House painter • Survey taker • Sheet metal fabricator • Commercial duct work Installer • Tax preparer • Wing Zone delivery guy • Exterminator

How to share with your neighbor • Look and listen as much as you talk • Tell 2-4 people then stop • Wait til I say go • When I say “go” make sure your neighbors know to tell 2-4 people when sharing • GO
Types of things I have you repeat and share with your neighbor • Formulas • Rules/steps • Hints at solving • Future content
ZEROS=ROOTS=SOLUTIONS =X INTERCEPTS
Why am I a Math teacher? • I love math • I love figuring out how numbers work • I love stretching my brain • I’ve been given a gift of understanding math • I love kids • I consider it an honor to have an influence on your life. • Kids are more real than grown-ups • Seeing that A-ha moment is a rush
People cheat So Show your work
People do this So keep your hands above the desk Nothing but notebook-writing utensil and Calculator
Lets talk expectations/rules Be Reasonable Be Respectful Be Responsible
NO EXCUSES • I was checking the time • It’s my Mom • I was using the calculator This is your warning I see it I call security
I need your attention • When I do this • You do this
Calculator PolicyI need something as valuable to you as these calculators are to mea.k.a. collateralSchool IDCell phoneWalletiPod/mp3 playerkeysyour friends cellphone…. GO When I say go Make sure everyone around you understands the calculator policy
I need your attention • When I do this • You do this
When I say go • Form an orderly line and have your collateral ready. • No negotiating and everyone has a calculator when we are done. GO
Looking for two numbers that add to column A and Multiply to column B A B • 7 • 6 • 8 • -3 • -5 • 13 • 1 • -4 • 12 • 8 • -9 • -10 • 6 • 30 • -2 • 4 3 and 4 4 and 2 9 and -1 -5 and 2 -3and -2 3 and 10 2 and -1 -2 and -2
Solving Equations Good old solving for x
I need your attention • When I do this • You do this
1) Get rid of ( ) --distribute 2) Combine like terms 3) Get variables on same side – use inverse operation 4) Solve 2 step equation Use Steps to Solve Equation:2(x + 7) + 3 = 5x - 1 2x + 14 + 3 = 5x – 1 2x + 17 = 5x - 1 -2x -2x 17 = 3x - 1 +1 +1 18= 3x Undo by using inverse 3 3 6 = x
(16x + 60). Solve 9x–5= (16x + 60) 9x – 5= 1 1 4 4 EXAMPLE 2 Write original equation. 9x – 5 = 4x + 15 Distributive property -4x -4x 5x – 5 = 15 Subtract 4xfrom each side. +5 +5 5x=20 Add 5 to each side. 5 5 x = 4 Divide each side by 5.
For you to do 1. 24 – 3m = 5m 2. 20 + c = 4c – 7 3. 9 – 3k = 17k – 2k 4. 5z – 2 = 2(3z – 4) 5. 3 – 4a = 5(a – 3) • 3 • 9 • 1/2 • 6 • 2
