The Metric System is a very easy system to learn.  
It is very orderly. 

Everything is based on the number 10.

We have ten fingers...

And we have ten toes...

And that really helps us count. 
 
In fact, those ten fingers and ten toes really helped people count long ago. 

And it was because of those ten fingers and ten toes that 
our system of numbering and grouping by tens developed!

The metric system was created around 200 years ago in France.  
The French people call it the International System -- or SI -- 
because they say things backwards in France.

So say good bye to our silly system of measuring.  It is time for a change.  In fact, you probably know some words already!

35-millimeter camera
16-millimeter movie camera
2-liter soda bottle

Whether you are measuring distance, weight, or  volume 
 the measurement words are all very much alike.  They all start with certain prefixes:

Can you remember this sentence??
KING   HENRY'S   DAUGHTER   DRANK   CHOCOLATE  MILK
If you can, then you  can learn the prefixes in order very easily!  Try it.
