  2. Once Upon a Time… in a faraway land named Metric Kingdom, there lived a king who loved chocolate milk. His name was King Henry.

  3. Throughout his kingdom, King Henry made sure that all of the cows were fed great supplies of chocolate to continue to provide him with his beloved chocolate milk drink.

  4. King Henry drank chocolate milk with his breakfast. He drank chocolate milk with his lunch. He drank chocolate milk with his dinner. He even drank chocolate milk for his bedtime snack. King Henry drank chocolate milk by the liters!

  5. King Henry was so obsessed with his chocolate milk that he wrote a decree making it illegal for anyone to drink chocolate milk, except for himself.

  6. After visiting the King, the doctor revealed something miraculous: the King was the healthiest he’d ever been! King Henry’s wife was concerned about the amount of chocolate milk he was drinking. She called the doctor to check him out.

  7. The chocolate milk had made the King stronger taller faster and handsomer!

  8. After hearing the news, the King drank more chocolate milk than ever. He drank, and drank, and drank his chocolate milk, until one day King Henry unexpectedly died! His body just couldn’t process all of the chocolate! Sadly, King Henry Died By Drinking Chocolate Milk

  9. The Gift King Henry Left for his People of Metric Kingdom: King Henry may have died a long time ago, but his Metric Kingdom remembers him every year when students learn metric conversions. His RIP statement helps us remember the prefixes for metric measurement and how to order the units from greatest to smallest.

  10. King Henry Died Unexpectedly Drinking Chocolate Milk Kilo Hecto Deka Unit Deci Centi Milli When converting metric units from one unit to another, you can use this simple phrase to keep you from making any mistakes.

  11. Metric System • Metric system is based on the power of 10. • Meter is a measure of length. • Gram is a measure of mass. • Liter is a measure of liquid volume.

  12. Prefixes

  13. Converting Units • To convert from one unit to another is like walking up and down steps. • Going Up • When going from a smaller unit to a larger unit, you move UP the steps and the decimal moves to the LEFT. • Going Down • When going from a larger unit to a smaller unit, you move DOWN the steps and the decimal moves to the RIGHT.

  14. What to do first in the problem4.5 m = __ cm ? Start here at Meters and Move DOWN to Centimeters. Decimal place moves to the RIGHT the same number of steps. • Find the measurement your starting with on the ladder. • Find the measurement you are converting to on the ladder. • Identify if you are moving up or down the ladder. • Then identify if you are moving your decimal to the right or left. Kilo Hecto Deka • Base Units Include: • Gram • Liter • Meter Base Deci 4.5 Centi Milli

  15. 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

  16. Practice • 3 meters = ______ centimeters • 40 liters = ______ deciliters • 600 milligrams = _______ grams • 5 kilometers = __________ hectometers • 70 centimeters = _________ meters

  17. 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

  18. 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

  19. 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
