4. We put several centimeters together to make a metric ruler.1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
If we add those numbers to the stick, this is what it will look like. 30

9. Let’s make it bigger to see these little parts.
What if we wanted to measure really small things? If you look very closely at a centimeter, you’ll see it’s divided up into ten tiny parts.
Let’s make it bigger to see these little parts.

10. Each one of these tiny parts is called a millimeter.1 2 3 4 5 6 7 8 9 10
There are 10 millimeters in every centimeter.

Remember though, millimeters are very, very tiny. 10 of them are in every centimeter.
Some items that may need to measured with millimeters are eraser tips, fingernails, and eye lashes.

12. Chris Cuppett – Wicomico County, Maryland
When we need to measure larger items, we need to put a lot of centimeters together. In fact we need 100 centimeters to make one meter.
This is about 30 centimeters, so we’d need a little over 3 of these to make a meter

13. Put all of these end to end and you make a meter stick.

To measure long distances with metrics we use kilometers. To make a kilometer, it takes 1,000 meters.

18. 1,000 of these end to end would make 1 kilometer.
Too many to show

If you look at the speed dial in the car, you’ll see that the speed of the car can be seen in two ways, miles per hour (MPH) and kilometers per hour (km/h).

When we write numbers in metrics, we usually don’t write out the whole word. There are shorter names for each unit of measurement.

22. Metric Abbreviations Millimeter – mm Centimeter – cm Meter – m
Kilometer - km
Pretty easy to remember, right?
