2. Pop Quiz: Write down which Property of Exponents can be applied to the following expressions and evaluate- show your work!

3. Converting from Standard Form to Scientific Form MAFS.8.EE.1.3: Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other.

4. Today’s Goals and Agenda By the end of class today I will: Know how to convert between Standard Form and Scientific Notation I plan to do this by: ▪ I Do: Scientific Notation Notes ▪ We Do: Mini White board Practice ▪ You Do: Matching Cards Activity

12. Number Operations in Scientific Notation MAFS.8.EE.1.4:Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities. Interpret scientific notation that has been generated by technology.

13. Today’s Goals and Agenda By the end of class today I will: Be able to solve expressions using numbers in Scientific Notation I plan to do this by: ▪ I Do: Solving Scientific Notation Problems Notes ▪ We Do: Mini White board Practice ▪ You Do: Finish Matching Poster or Start Home Learning

16. Write this Down! Multiplying in Scientific Form ▪ When multiplying numbers expressed in scientific notation, the exponents can simply be added together. ▪ Examples: 10 1 x 10 2 = 10 x 100 = 1,000 = 10 3 Checking that we see: 10 1 x 10 2 = 10 1+2 = 10 3 Similarly 10 1 x 10 -3 = 10 1-3 = 10 -2 = 0.01 Again when we check we see that: 10 x 1/1000 = 1/100 = 0.01

17. Let’s Practice! (4.0 x 10 5 ) x (3.0 x 10 -1 ) The 4 and the 3 are multiplied, giving 12, but the exponents 5 and -1 are added, so the answer is: 12 x 10 4, or 1.2 x 10 5 Let’s check: (4 x 10 5 ) x (3 x 10 -1 ) = 400,00 x 0.3 = 123,000 = 1.2 x 10 5 Pull Out Your White Boards!

20. P-20 You Do: Matching Cards Set A 1. Take turns to match a card in scientific notation with a card in decimal notation. 2.Each time you match a pair of cards explain your thinking clearly and carefully. Place your cards side by side on your desk, not on top of one another, so that everyone can see them. 3.Partners should either agree with the explanation, or challenge it if it is not clear or not complete. 4.It is important that everyone in the group understands the matching of each card. 5.You should find that two cards do not have a match. Write the alternative notation for these measurements on the blank cards to produce a pair.

21. P-21 Matching Cards Set B 1. Match the objects in Card Set B with the corresponding paired measurements from Card Set A. You may want to put the objects in size order first to help you. 2. It is important that everyone in the group agrees on each match. 3. When you have finished matching the cards, check your work against that of a neighboring group. 4. If there are differences between your matching, ask for an explanation. If you still don’t agree, explain your own thinking. 5.You must not move the cards for another group. Instead, explain why you disagree with a particular match and explain which cards you think need to be changed.

24. Today’s Goals and Agenda By the end of class today I will: Demonstrate my Knowledge of Scientific Notation through a Project! I plan to do this by: ▪ You Do: Giant Burgers Advertisement! ▪ We Do: What’s my grade? Do I have any missing assignments?

25. Giant Burgers! You are now the head of advertising at Giantburgers! One of the top fast food joints in America. The company’s current slogan is “Every Day 7% of Americans eat at Giantburger Restaurants”. Your job is to find out if that’s true. Once you’ve completed that you need to make a new slogan for Giantburger that is more accurate and catchy, you will make that advertisement on a poster and present it to the board of directors.

26. Two Options: Option 1: Work on your Burger Project- Remember your Worksheet is due by the beginning of class tomorrow and your advertisement is due Friday! Option 2: Come see me to find out what your grade is and if you are missing any assignments, or if you want tutoring for the exam.- You still have to complete the project!

27. Do Now: What questions do you still have from what we’ve learned so far? What is still confusing?(Rational/Irrational Numbers, Squares/Cubes, Laws of Exponents, Scientific Notation)

28. Today’s Goals and Agenda By the end of class today I will: Have had any questions I had on Unit 1 Answered and Know what I need to study tonight for my exam tomorrow! I plan to do this by: ▪ I Do: Class Questions and Answers ▪ We Do: Jeopardy! ▪ You Do: Study for your Exam tonight!

29. Review Game! ▪ Each group will have a turn to come up and spin the spinner ▪ The color the spinner lands on determines which type of question will be drawn from the deck: Purple- Rational/Irrational Numbers, Red- Approximating Irrational Numbers, Yellow-Square and Cube Roots, Green- Laws of Exponents, Orange- Scientific Notation, Blue-Wild Card (Team Picks Category) ▪ Every team will then need to write the answer on their mini white board ▪ The team who gets the answer correct first gets to shoot a ball in the cups to determine how many points their team just scored and gets to spin the spinner next
