I didn't realize just how hard it was to organize and condense information. After what seemed like FOREVER I have added the section called Mathematical Reasoning. Of course the section does not contain all I want to add, but it is a good start. In the Mathematical Reasoning section you will find concepts, content standards, and useful links for educators, parents, and online math games geared toward Pre-K aged children. Check back often because this is a work in progress and I am sure I've left something really important out.
