If you use Open Court, you should check out the great site Open Court Resources. This site has some great PowerPoint presentations and other resources for grades K-6 and for both the “new” and “old” OCR.
We’ve had some very good success in classrooms with giving the students PowerPoint presentations on their mobile devices (Palms, PPCs, iPods) and having them follow along with them while the teacher shows them on the big screen. Kids are more engaged in the content and retention is better.
Much thanks to Mr. Mathew Needleman, a classroom teacher and developer, for making these resources available.

That’s a great site! And thanks for the idea about using it on handhelds.
