Why use a Blog for Elementary School Students?

                         
           I'm sure there are a lot of questions as to why and how Elementary students would find a blog useful? Blogs can be really useful to do homework over. With a blog, I can post homework assignments and students can complete and turn it in the next day or they can just send it to me publicly over the blog. That way, other students will also be able to read there responses and give feedback on it as well. Of course we will be doing most of the work in class, but this just allows for better communicating between all three parties. Parents also will be able to get a better idea of what was covered in class that day and be able to contact me if needed with any questions. I can also post educational videos for students to watch and take a small quiz over, or also have them play an educational game that relates to what we learned in the classroom that day.
For example, watch this video and answer these questions for me.

1. Which one was the hour hand?
2. If the hour hand is in between both the 11 and 12, what hour is it?
3. What are the increments on a clock?
