Beginning Numbers-Subitizing (again)

Here is a great post from the blog Math is Not a Four Letter Word about why subitizing is important.  I think if we can help those kids who come to use with minimal number sense right away ... it could make all the difference when they try to tackle other math concepts.  I have been thinking about how to assess children's number sense knowledge.  So far I think Kathy Richardson's Counting Objects Assessment and Changing Number Asessment  is the right way to go.
