  1. Orders of Magnitude U1L11 Unit 1 Les.11: Orders of Magnitude

  2. Orders of Magnitude U1L11 • Andrew’s hamster has been busy! She had 2 babies • the first year . Each baby had 2 babies the next year. • Each of those babies had 2 babies the 3rd year. • How many babies were born the 3rd year? Show • your answer as a power. • 21 • 22 • 23 • 24 Unit 1 Les.11: Orders of Magnitude

  3. Remember!! • I am responsible for my own actions. • I will do my best at all times. • My education is mine only and can never be taken away. • I am worth it. I am worth the time. I am worth the energy. • I am somebody, and I will be successful this year and in years to come.

  4. Coming Up… • Monday: Orders of Magnitude • Tuesday and Wednesday: Review Unit 1 • Thurs: Unit 1 Test or More Review • Fri: Begin Unit 2 • Please note: • TIZ reflection - due Wednesday 10/8 • Graded lessons for Unit 1: 3, 5, 6, 9 – due Wednesday 10/8 Unit 1 Les.11: Orders of Magnitude

  5. Pet of the Day - Dewey SI: Scientific Notation

  6. Pet of the Day – Moses SI: Scientific Notation

  7. Pet of the Day – Rebekah SI: Scientific Notation

  8. TIZ reflection - due Wednesday 10/8 • Graded lessons for Unit 1: 3, 5, 6, 9 – due Wednesday 10/8 For Class Today: Click A if you want to stay in the main room and finish U1L11 lesson together Click B if you want to work on Unit 1 lessons or the TIZ Reflection on your own in a breakout room. If both of these are done, you may work in Study Island: Exponential Expressions or Scientific Notation Unit 1 Les.11: Orders of Magnitude

  9. TIZ reflection - due Wednesday 10/8 • Graded lessons for Unit 1: 3, 5, 6, 9 – due Wednesday 10/8 To Be Marked Present Today: Complete lessons in Unit 1 Complete TIZ Reflection: attach it to a kmail and send it to Mrs. Stewart You MUST complete the Google Doc at the end of class and tell me what you accomplished in class today Unit 1 Les.11: Orders of Magnitude

  10. How do I know what to write down or when to yell out the answer?? Look for these keys on the slides U1L6 Negative Exponents

  11. Calendar SI: Scientific Notation

  12. Goal • Determine the best order-of-magnitude estimate for a number. Unit 1 Les.11: Orders of Magnitude

  13. To get us thinking… Which number is 2 closest to? 1 10 Unit 1 Les.11: Orders of Magnitude

  14. To get us thinking… Which number is 7 closest to? 1 10 Unit 1 Les.11: Orders of Magnitude

  15. Order-of-magnitude estimate • acalculation that provides an answer that is accurate to the nearest power of 10 • Order of magnitude estimate is the power of 10 only. Unit 1 Les.11: Orders of Magnitude

  16. Unit 1 Les.11: Orders of Magnitude

  17. Determining the Best order of Magnitude Estimate Step 1: Write the number in Scientific Notation Step 2: Look at the Single digit. Is it closer to 1 or 10? Step 3: If it is closer to 1, the order of magnitude is the current power of 10. If it is closer to 10, add one to the power of 10. Unit 1 Les.11: Orders of Magnitude

  18. Determining the Best order of Magnitude Estimate Step 1: Write the number in Scientific Notation Step 2: Look at the Single digit. Is it closer to 1 or 10? Step 3: If it is closer to 1, the order of magnitude is the current power of 10. If it is closer to 10, add one to the power of 10. Unit 1 Les.11: Orders of Magnitude

  19. Determining the Best order of Magnitude Estimate Step 1: Write the number in Scientific Notation Step 2: Look at the Single digit. Is it closer to 1 or 10? Step 3: If it is closer to 1, the order of magnitude is the current power of 10. If it is closer to 10, add one to the power of 10. Unit 1 Les.11: Orders of Magnitude

  23. Summary • Determine the best order-of-magnitude estimate for a number. Give me a green check if we reached this goal. Unit 1 Les.11: Orders of Magnitude

  24. Assignment • Complete Unit 1, Lesson 11 Assessment • Start working on Lesson 14 to review for the Unit 1 Test (opens on Thursday) Unit 1 Les.11: Orders of Magnitude

  25. Exit Ticket Determine the Best Order of Magnitude for 0.00000846 10-6 10-5 106 105 I need help Unit 1 Les.11: Orders of Magnitude

  26. Goals • Compare numbers that are expressed as the product of a single digit and a power of 10. • Estimate a quantity as the product of a single digit and a power of 10. Unit 1 Les.11: Orders of Magnitude

  27. Rounding Rules Review • Underline the rounding digit. • Look at the number to the right • If it is… • 0 – 4: The rounding digit will stay the same. • 5 – 9: The rounding digit will bump up 1 Five or more, raise the score. Four or less, let it rest. Five or above, give it a shove Unit 1 Les.11: Orders of Magnitude
