  1. AIM: Today, you will learnhow length is measured in the Metric System. VOCABULARY Meter-stick meter decimeter centimeter millimeter

  2. OBJECTIVE To understand and successfully measure length using the metric system

  3. What is this called? Meter stick

  4. The base (standard) unit of length in the metric system is called…? The METER(m)

  5. How many meters are there on a meter stick? 1 meter

  6. How many years are there in a decade? What number is the decimal system based on ? Sooooo……How many decimeters do you think there are in a meter?

  7. PROVE IT!!!!! Everyone, now, COUNT THE DECIMETERS ON YOUR METER STICK !

  8. How many years are there in a century? How many cents are there is a dollar? How many legs does a centipede have? Sooooo……How many centimeters do you think there are in a meter?

  9. PROVE IT!!!!! Everyone, now, COUNT THE CENTIMETERS ON YOUR METER STICK !

  10. How many years are in a millenium? How many legs does a millipede have? So what do you think the prefix “milli” mean? Sooooo……How many millimeters do you think there are in a meter?

  11. PROVE IT!!!!! Everyone, now, COUNT THE MILLIMETERS ON YOUR METER STICK ! Just kidding…

  12. What does the word abbreviation mean? The abbreviation for meters is “m”. The abbreviation for centimeters is “cm”. The abbreviation for millimeters is “mm”

  13. Let’s try some Metric length conversions!

  14. Math Problem If 100 cm = 1m Then how many cm = 2 meters? 200 cm How did you figure that?

  15. Math Problem If 100 cm = 1 meter Then how many cm = 1.5 meters? 150 cm How did you figure that?

  16. Math Problem If 1 m = 100 cm Then 300 cm = ? m 3 How did you figure that?

  17. Math Problem If 100 cm = 1 m Then 350 cm = ? m 3.5 m How did you figure that?

  18. Metric Rule To convert meters to centimeters MULTIPLY by 100…OR take 2 hops to the right on the step chart. How do you think you convert centimeters to meters? DIVIDE by 100…OR take 2 hops to the left on the step chart

  19. Math Problem If 1000 mm = 1 meter Then 2 meters = ? mm 2000 mm How did you figure that?

  20. Math Problem If 1000 mm = 1m Then how many mm = 1.5 meters 1,500 How did you figure that?

  21. Math Problem If 1,000 mm = 1m Then 3000 mm = ? m 3.0 m How did you figure that?

  22. Math Problem If 3,000 mm = 3m Then 3,500 mm = ? m 3.5 m How did you figure that?

  23. Metric Rule To convert meters to millimeters MULTIPLY by 1000…OR take 3 hops to the right on the step chart. How do you think you convert millimeters to meter? DIVIDE by 1000… OR take 3 hops to the left on the step chart.

  24. So there are 100 cm in a m. And, there are 1000 mm in a m. Use your metric rulers right now to COUNT how many mm there are in 1 cm.

  25. Math Problem If 1 cm = 10 mm Then how many mm = 2 cm? 20 mm How did you figure that?

  26. Math Problem If 1 cm = 10 mm Then 1.5 cm = ? mm 15 mm How did you figure that?

  27. Metric Rule To convert centimeters to millimeters MULTIPLY by 10…OR take one hop to the right on the step chart How do you think you convert millimeters to centimeter? DIVIDE by 10… OR take one hop to the left on the step chart

  28. Math Problem If 10 mm = 1cm Then 30 mm = ? cm 3 How did you figure that?

  29. Math Problem If 30 mm = 3 cm Then 35 mm = ? cm 3.5 cm How did you figure that?

  30. SUMMARY The base (standard) unit of length in the metric system is the ________? m is the abbreviation for _____? cm is the abbreviation for _____? mm is the abbreviation for ____?

  31. SUMMARY 1 meter = 1000 mm1 meter = 100 cm1 centimeter = 10 mm You can use your metric conversion shortcut:K H D b d c mTo make it easier to convert between units!
