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) the base unit of volume.

6. Prefixes

7. King Henry Died By Drinking Chocolate Milk Kilo Deka Basic Unit Deci Centi Milli Hecto Liters Meters Grams

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

9. 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 .

10. 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 .

11. Practice Time 4.5 m = ? cm

12. 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

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

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

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

16. 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

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

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

19. 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

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

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

22. 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

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

24. 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

25. 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

26. 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
