Wouldn't it be fun to have our students make a few of these videos and post them on this page? It looks like they have videos from a variety of places. Check out the math addition videos for ideas.
Not to go against the grain, but I found this article interesting, especially given all the high-tech parents. As we continue to integrate technology, it's important to remember that technology is not what makes good teaching and that we need to constantly evaluate what is appropriate for our children.
The more I use this website the more I love it. Mostly science but also math activities and websites. This site has lists of absolutely every good activity and interactive on the internet, by topic (well, maybe not every one. But more than I have found in any other single site).
