Decimals

The students are pretty comfortable with place value of whole numbers.  So it must be time to introduce the reading of decimals.  They have seen decimals in our measurement unit, but there were a lot of 'points' being said.

They know that our number system is a base 10 system and that each 'level' going up is 10 more, and that getting smaller means it is ten pieces of.  Now they need to understand that the same thing happens across the decimal.  Next to the decimal is the tenths, then the hundredths, and then the thousandths.  The decimal is where they finally get to use that 'and' that they wanted to say before.

Practice writing numbers up to millions and then with up to three decimal places.  Also writing the number words for each of the numbers.
