3. Metric Conversions Ladder Method T. Trimpe 2008 http://sciencespot.net/

4. 1 2 3 MetersLitersGrams How do you use the “ladder” method? 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction. Starting Point Ending Point __. __. __. 2 3 1 Ladder Method KILO1000Units HECTO100Units DEKA10Units DECI0.1Unit CENTI0.01Unit MILLI0.001Unit 4 km = _________ m How many jumps does it take? 4. = 4000 m

5. BASIC UNITS OF THE METRIC SYSTEM • The meter(m) is the base unit of length. • The gram(g) is the base unit of mass. • The liter (L)is the base unit of volume.

6. Prefixes

7. Converting Units To convert from one unit to another is like following directions on a map. Which way? Left or Right?

8. Going Left??? When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT .

9. Going Right??? When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT .

10. Practice Time 4.5 m = ? cm

11. What to do first in the problem 4.5 m = __ cm ? Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces. . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 4.5

12. As you move the decimal you will need to add zeros. . 4 . 5 0

13. Is this your Final Answer? 4.5 m = 450 cm

14. Let’s do another one! 6.6 liters = _____ mL

15. What to do first in the problem 6.6 L = __ mL ? Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces. . . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 6.6

16. Check your answer! 6.6 liters = 6,600 mL

17. Let’s Go the Other Way! 3,580 mm = _______ m?

18. Let’s move to the left this time. 3,580mm = ___________m? Start at Millimeters and move to the Left to Meters. Decimal place moves to the LEFT three spaces. . . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 3 5 8 0

19. Check your answer: 3,580mm = 3.58m

20. Quiz Time • 28 cm = ? mm • 438 cm = ? m • 72 g = ? mg • 202 g = ? Kg • 2L = ? mL

21. How did We do?? 1. 28 cm = 280 mm 4.38 m 2. 438 cm = 3. 72 g = 72,000 mg 4. 202 g = 0.202 kg 5. 2 L = 2,000 mL

22. Now we will practice with the following worksheets • Units of length • Metric conversion

23. Compare using <, >, or =. 56 cm 6 m 7 g 698 mg Conversion Practice Try these conversions using the ladder method. 1000 mg = _______ g 1 L = _______ mL 160 cm = _______ mm 14 km = _______ m 109 g = _______ kg 250 m = _______ km

24. Compare using <, >, or =. 25) 63 cm 6 m 27) 5 g 508 mg 29) 1,500 mL 1.5 L 26) 536 cm 53.6 dm 28) 43 mg 5 g 30) 3.6 m 36 cm

25. Metric Conversion Challenge Write the correct abbreviation for each metric unit. 1) Kilogram _____ 4) Milliliter _____ 7) Kilometer _____ 2) Meter _____ 5) Millimeter _____ 8) Centimeter _____ 3) Gram _____ 6) Liter _____ 9) Milligram _____ Try these conversions, using the ladder method. 10) 2000 mg = _______ g 15) 5 L = _______ mL 20) 16 cm = _______ mm 11) 104 km = _______ m 16) 198 g = _______ kg 21) 2500 m = _______ km 12) 480 cm = _____ m 17) 75 mL = _____ L 22) 65 g = _____ mg 13) 5.6 kg = _____ g 18) 50 cm = _____ m 23) 6.3 cm = _____ mm 14) 8 mm = _____ cm 19) 5.6 m = _____ cm 24) 120 mg = _____ g
