  1. Welcome to our Web Quest on Scientific Notation! The Mission: To be able to write numbers in expanded notation and scientific notation. The Plan: To follow the directions of the Web Quest and complete the Web Quest packet The Rules: 1. All directions are written in RED 2. You must follow ALL directions given. DO NOT SKIP any directions. If you are asked to watch a video, you must watch the ENTIREvideo before moving on. 3. Click the on each page when you are ready to move on. ARE YOU READY TO BEGIN? YOU KNOW WHAT TO DO!

  2. With a partner, compare your answers to Study Link 7-2. Then click on the link below to check your work. H:\2011-2012 Fifth Grade\Math\Study Link7-2DOC.pdf

  3. Record your answers to the following questions on your Web Quest packet(#1-6)(You may need to use your Study Link 7-2 to help you.) One thousand equals what power of 10? Which prefix means “thousand”? What is another name for 10 to the 6th power? Which prefix means “million”? What does the prefix “tera-” mean? 1 trillion equals what power of 10? Now click here to see the answers and check your work. Record how many you got correct on your Web Quest worksheet.

  4. 1. Complete questions 1-10 on p. 214 in your Web Quest packet. ***Remember…Calculations with exponents are done BEFORE other factors are multiplied. 2. Then, read about scientific notation on p. 214 in your packet. 3. Record the definition for “scientific notation” on your vocabulary list. 4. Complete questions 11-14 on p. 214 in your Web Quest packet. 5. Click here to check your work.

  5. Expanded Notation To write a number in EXPANDED NOTATION, multiply each digit in the number by the value of it’s place. Example: 3,269 The 3 is in the 1,000’s place. 3 * 1,000 The 2 is in the 100’s place. 2 * 100 The 6 is in the 10’s place. 6 * 10 The 9 is in the 1’s place. 9 * 1 So, the EXPANDED NOTATION looks like this: (3 * 1,000) + (2 * 100) + (6 * 10) + (9 * 1) OR 3000 + 200 + 60 + 9

  6. Click on the link below to watch a video on “expanded notation”. http://www.youtube.com/watch?v=uBuofv6Bbn0 Now copy the definition below for expanded notation into your vocabulary list. expanded notation- a way of writing a number as the sum of the values of each digit. (Ex. 356 is 300 + 50 + 6 in expanded notation)

  7. Let’s Practice! Click the link below to practice changing numbers in Expanded Notation to Standard Form. http://www.aaamath.com/g31d_px1.html#section2 Now complete p. 217 in your Web Quest packet. Click here to check your work. How did you do? IF… You think you need more practice, click here. IF… You think you’ve mastered Expanded Notation, click the arrow to move on.

  8. Let’s learn about Scientific Notation! So, what IS scientific notation? Read about scientific notation by clicking here. Click here to learn about scientific notation.

  9. Let’s look at an EXAMPLE: Let’s write 52,000 in scientific notation. -Write the first number in the one’s place followed by a decimal and any other NON- ZERO numbers - 5.2 -Next, multiply that number by 10 -5.2 x 10 -Finally, count how many places you moved the decimal. This is your power of ten exponent. - 5.2 x 104

  10. Try it by yourself! 63,000 = 6.3 x 104 412,000 = 4.12 x 105 Let’s try one more! 1,236,000 = 1.236 x 106 How do you feel? Great!

  11. Are you ready to practice? Now complete worksheet 214B on scientific notation in your Web Quest packet. Click here to check your work.

  12. Are you ready for a challenge? Great! Now let’s try an activity using what you know about scientific notation! Read worksheet p. 215. Then complete worksheet 216 in your Web Quest packet. Click here to check you work. Click here for a challenge with scientific notation!

  13. Way to Go! You have completed the Web Quest! You may now: Work on Challenge Lab #7 Go back and revisit any practice games from the Web Quest Go onto Mrs. Rabi’s website and practice math links from Unit 7.
