Subject: Re: Decomposing Numbers

I could only find a reference to decomposing in state standards in SC
standards for K-2:

"D. Develop a sense of whole numbers and represent and use them in
flexible ways, including relating, composing, and decomposing

This seemed to lead to Tufts U. and the NCMT.  But they gave no
example of what is meant.  However, I did google this as well as Ask
Jeaves and found that mostly they mean representing a number in
different ways such as:

7=3+4, 7=2+5 etc.  There was a bit about borrowing and regrouping
also.  But SX were only talking about kids up to 2nd grade, so that
may not include borrowing and reqrouping.

The problem with many state standards is they are written in language
that most people don't understand the language.  When, VA first came
out with the standards many teachers didn't understand what was
intended until finally lots of framework material was made available
which gave examples.  

I susgest you write to your state dept of education and see what is
meant.  I think it is sad, when these high level documents are put out
with no examples as to what is meant.
