I visited several different 4th grade blogs for different teachers and educational sites. I find using these is beneficial because they often have links and activities for the same curriculum I am covering. It's great to share ideas with others. I don't usually comment on a blog unless I have a question that needs to be answered. I enjoy reading comments, and often find if I have a question regarding the blog post, my answer can be found in the comments 9 times out of 10.
