27. Nice Job!
If you can multiply & divide by 10 (or any power of 10), then the metric system will be easy for you.

28. THE METER
The meter is the starting point for the metric system.
START

29. Here’s a meter stick!

30. It takes 10 decimeters to make up 1 meter.

31. It takes 10 centimeters to make up 1 decimeter.

32. If 1 meter = 10 decimeters and 1 decimeter = 10 centimeters then how many centimeters make up 1 meter?

33. That’s right! 1 meter = 100 centimeters

34. 100centimeters = 1 meter

35. It takes 10 millimeters to make up 1 centimeter.
Boy, that’s small!

36. If 1 meter = 10 decimeters and 1 decimeter = 10 centimeters and 1centimeter = 10 millimeters then how many millimeters make up 1 meter?

37. That’s right! 1000 millimeters = 1 meter

38. It takes 10 millimeters to make up 1 centimeter.
Millimeters are so small that they almost run together.

39. Now let’s take a closer look at some measuring devices.

40. This is a magnified image of a ruler/meter stick.1 2 3 4
This is one centimeter.

41. This is a magnified image of a ruler/meter stick.1 2 3 4
This is half of a centimeter.

42. This is a magnified image of a ruler/meter stick.1 2 3 4
This is one millimeter.

43. This key measures 3 cm. 1 2 3 4

44. Or you could say that it measures 30 mm.1 2 3 4

45. This key measures 2.5 cm. 1 2 3 4

46. Or, you could say that it measures 25 mm.1 2 3 4

47. 1 2 3 4
This toy car measures 4.2 cm.

48. 1 2 3 4
Or, you could say it measures 42 mm.

49. The metric system deals with powers of 10
1 meter =
10 decimeters =
100 centimeters =
1000 millimeters

50. How many centimeters make up 2 meters?

51. That’s right! There are 200 centimeters in 2 meters.

52. How many millimeters make up 2 meters?

53. That’s right! There are 2000 millimeters in 2 meters.

54. How many decimeters make up 2 meters?

55. That’s right! There are 20 decimeters in 2 meters.

56. The metric system really is 10 times better than our standard system of measurement. It is very easy to convert from one unit to another.

57. You must simply multiply by 10, 100, or 1000
You must simply multiply by 10, 100, or OR You must simply divide by 10, 100, or 1000.

58. The end.
