Have you seen this site with great Powerpoint presentations of Everyday Math algorithms? The site was put together by South Western School District in Pennsylvania. I like to use them at some point during our instruction of these skills in class, but I also like to use them as a reference tool for parents. It makes it much easier for them to understand what their child is learning.
