  2. Learning Target • I will collaborate with my table and class and learn how to use the chart to convert within the metric system.

  3. Class Challenge • Everyone scores 3 out of 3 – • It never has happened before. • Doesn’t mean it can’t happen now!

  4. You need scratch paper today: • There are 1000 meters in a kilometer. How many meters are there in 6.62 kilometers? • There are 1/1000 meters in a millimeter. How many millimeters are there in 3 kilometers?

  5. Far Side – Sort Of

  7. Measuring

  8. What are three things we can measure? • #1 – Weight (Mass) • We use “grams” • #2 – Volume • We use “liters.” • #3 – Distance • We use “meters.”

  9. Converting within the Metric System Its as easy as moving the decimal point.

  10. The Table is the Key

  11. For Example: • I want to convert 3 KILOMETERS to MILIMETERS. • Grab your table and let’s begin.

  12. Answer the Following: • Which number is kilo? • Which number is mili? • What is the difference between the two? • 7 (kilo) – 1 (mili) = 6 • WE WILL MOVE THE DECIMAL 6 PLACES! • (But, in which direction?)

  13. If we move between Kilo and Mili on the table….. • In which direction are we moving? • Right or left? • RIGHT • We will move the decimal SIX places to the RIGHT.

  14. Summary • 3 Kilometers = • 3000000 milimeters • A very long road!

  15. The instructions written on your chart 1) Write down the number for the first prefix 2) Write down the number for the second prefix 3) Subtract the two numbers 4) Determine which direction you move on the table between the two 5) Move the decimal

  16. Another Problem I want to convert 3 dl to 3 hl What is the first number? What is the last number? What is the difference between the two?

  17. 6 – 3 = 3! • Which direction? • Left

  18. Summary: • 3 deciliters = .003 hekaliters

  19. WARNINGS • If there is NO PREFIX, this means we are talking about #4 on the table. • If there is one letter, that means that we are talking about #4 on the table. • One M ALONE stands for Meter – not Mili! • When moving to the left, if there are no more numbers, you need to include a zero for each space you need to move.

  20. Practice Problems 50 meters = ???? Km 2.3 mL = ???? cL .001 hg = ???? g

  21. Practice problems • 4) 84 dg = _______ cg • 5) 100 L = __________ Kl • 6) 82.34 hm = __________ m • 7) 16.1 mm = __________ hm
