  1. WELCOME TO CAHSEE Week Five

  2. NOTES- any slide with a green title should be written down in your notebook.

  3. Lesson #9- Measurement and Geometry 1.1

  4. Ratios and Proportions (10mins) • Ratio- comparing two amounts. • 1 hour • 60 minutes • Proportions- two ratios that equal each other. • 1 hour = 2 hours • 60 minutes x minutes

  5. Example (write down the entire problem) It takes you 3 hours to ride your bike from Downtown LA to Orange County. You ride the total 65 miles without stopping. What is your average speed in miles per hour? 3 hours = 1 hour 65 miles x miles 3x= 65 3 3 x= 21.66, round off to the nearest tenth= 21.7 miles per hour

  6. Steps 1) Ratios= units must match! 3 hours = 1 hour 65 miles x miles **** Hours on top and miles on bottom. 2) Cross multiply 3) Divide to find x.

  7. Bootcamp Practice (15 mins) • Pages 77-78 you may write on.

  8. Bootcamp Practice • Raise your hand if you need any help • Ask questions NOW, the Cahsee will be too late! *Teacher will determine grouping (independent, pairs, etc.)

  9. Page 77 CHECK YOUR WORK- 2 mins

  10. Page 78 CHECK YOUR WORK

  11. Lesson #10- Measurement and Geometry 1.3

  12. Rates- 8 mins • Rate- type of ratio, amounts are related to each other.

  13. Example #1 If you drove from Downtown LA to San Diego it would take your 2 hours for the 123 miles. What’s your car’s rate of speed? 123 ÷ 2= 61.5 miles per hour

  14. Example #2 It took 7 workers 5 person-days each to complete a job. What was the total number of person-days needed to complete the job? 7x 5= 35 days

  15. Bootcamp Practice (10 mins) • Pages 82- 83- you may write on.

  16. Bootcamp Practice • Raise your hand if you need any help • Ask questions NOW, the Cahsee will be too late! *Teacher will determine grouping (independent, pairs, etc.)

  17. Page 82 CHECK YOUR WORK- 2 mins

  18. Page 83 CHECK YOUR WORK- 3 mins

  19. Exit Slip: (10 mins) • Get your assigned computer/ close notebook • Log-on/ www.achievedata.com/zoom/test • Use the test key from the CAHSEE BOOTCAMP file cabinet under Mrs. Kelley’s page • Exit Slip Name- CB Math Week Five Exit Slip (4 questions)

  20. Time to Switch (1 minute stretch break before we start the next subject)

  21. Reminders: (1 min) • Sign-out (computer tracker) • Last 3 Bootcamp Sessions • 11 school days till the CAHSEE! • Study over your notes nightly • Room must be left spotless (no trash, I will check your desk before dismissal)
