Notes #36N1 Demonstrate an understanding of place value, including numbers that are:

• greater than one million • less than one thousandth. 

6N1.1 Explain how the pattern of the place value system, i.e., the repetition of ones, tens and hundreds within each period, makes it possible to read and write numerals for numbers of any magnitude.

Reading decimals is easy, you'll see.

They have two names like you and me.

First say the name as if there were no dot,

Then say the name of the last place value spot.
