Use a straight edge and pencil, make a table something like this:

1000's | 100's| tens| ones|.|tenths|100ths|1000ths|
       |    3 |   2 |   1 |.|   0  |   0  |   7   |

Enter 321.007 z(say "three hundred twenty-one and seven thousandths")

This the same as saying 321 7/1000.  That is why they call them
decimal fractions.  

Avoid saying "321point007."

She will get the idea if you give her several examples.

You say and at the decimal point.  That is the only time you say and. 


Numbers between 21 and 99 get a - between such as twenty-0ne.
