2. Reading a Straight Edge Created By: Dr. A. Dávila

3. Look at your straight edge closely to identify the customary (in for inches, ft for feet) or the metric side (cm for centimeter, mm for millimeter).

4. Most straight edge rulers have an excess edge.

5. If it does have an excess edge, start measuring from the first mark.

6. Each number identifies a whole. 1 centimeter

7. Notice the longer line segment and its corresponding number. whole centimeter

8. Notice the longer line segment and its corresponding number. This identifies the first whole centimeter. whole centimeter

9. Count the number of spaces between each line segment. Each space represents a millimeter. How many millimeters make a whole centimeter? fractions of a centimeter

10. Notice the first small line segment. This small line segment represents the first millimeter (on the meter side of a straight edge). 1 millimeters or 0.1 (1/10) of a cm

11. Notice the first small line segment. This small line segment represents the first millimeter (on the meter side of a straight edge). 2 millimeters or 0.2 (2/10 or 1/5) of a cm

12. Notice the first small line segment. This small line segment represents the first millimeter (on the meter side of a straight edge). 3 millimeters or 0.3 (3/10) of a cm

13. Notice the first small line segment. This small line segment represents the first millimeter (on the meter side of a straight edge). 4 millimeters or 0.4 (4/10 or 2/5) of a cm

14. Notice the first small line segment. This small line segment represents the first millimeter (on the meter side of a straight edge). 5 millimeters or 0.5 (5/10 or 1/2) of a cm

15. It takes 10 millimeters to make a whole centimeter. one centimeter one millimeter

16. How many centimeters make a whole decimeter? one decimeter

17. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? one decimeter is equal to 10 cm

18. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? 1/10 (0.1) of a decimeter

19. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? 2/10 or 1/5 (0.2) of a decimeter

20. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? 3/10 (0.3) of a decimeter

21. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? 4/10 or 2/5 (0.4) of a decimeter

22. It takes 10 centimeters to make a whole decimeter. How many decimeters make a meter? 5/10 or 1/2 (0.5) of a decimeter

23. Relating the Metric System (Systéme Internationale) to the Decimal System Created By: Dr. A. Dávila

24. Meter (m) is the basic unit for length or distance

25. 10 millimeters is equivalent to a centimeter

26. 10 centimeters is equivalent to a decimeter

27. 10 decimeters is equivalent to a meter

28. 10 meters is equivalent to a dekameter

29. 10 dekameters is equivalent to a hectometer

30. 10 hectometers is equivalent to a kilometer

31. The metric system is similar to the decimal system.

32. Each place to the right is 10 times greater than the previous multiply by 10

33. Each place to the left is 10 times smaller than the previous place divide by 10

34. 6 kilometers is equal to

35. 6 kilometers is equal to 60 hectometers

36. 600 dekameters

37. 6 kilometers is equal to 60 hectometers 600 dekameters 6000 meters

38. 6 kilometers is equal to 60 hectometers 600 dekameters 6000 meters 60000 decimeters

39. 6 kilometers is equal to 60 hectometers 600 dekameters 6000 meters 60000 decimeters 600000 centimeters

40. 6 kilometers is equal to 600 dekameters 6000 meters 60000 decimeters 600000 centimeters 6000000 millimeters

41. 8 meters is equal

42. 8 meters is equal to 80 decimeters

43. 8 meters is equal to 80 decimeters equal to 800 centimeters

44. 8 meters is equal to 80 decimeters equal to 800 centimeters equal to 8000 millimeters

45. 8 meters is equal to
