YouTube safety for children doesn't allow for kids-level videos to be saved or made into playlists. Therefore, I found that some of the most useful educational videos for my students cannot be made into Playlists. I will have to copy the URLs and then create links to the videos. That's not much more work, and the links can be included in a Docs lesson plan. I can also load up the videos in advance. Here are some videos that I think will be useful for my 4th grade class: reviewing how to multiply and divide, and on sentence combining.
