  1. Welcome To Mr. Mealey’s MATH III

  2. I need your attention • When I do this • You do this

  3. 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

  4. 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

  5. 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

  6. 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)

  7. 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)

  8. Try These Examples • 3y + 7 = 25 • 5n – 2 = 38 • 12b + 4 = 28

  9. Check your answers!!! • y = 6 • n = 8 • b = 2

  10. 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

  11. Enough about me lets do some math

  12. I need your attention • When I do this • You do this

  13. 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

  14. Types of things I have you repeat and share with your neighbor • Formulas • Rules/steps • Hints at solving • Future content

  15. ZEROS=ROOTS=SOLUTIONS =X INTERCEPTS

  16. 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

  17. Bad People make life sucky for good people

  18. People cheat So Show your work

  19. People do this So keep your hands above the desk Nothing but notebook-writing utensil and Calculator

  20. Lets talk expectations/rules Be Reasonable Be Respectful Be Responsible

  21. 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

  22. Enough rules for a while lets do some more math 0

  23. I need your attention • When I do this • You do this

  24. 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

  25. I need your attention • When I do this • You do this

  26. 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

  27. I can do problems I haven’t seen

  28. 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

  29. Solving Equations Good old solving for x

  30. I need your attention • When I do this • You do this

  31. 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

  32. (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.

  33. 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
