multimedia project

I used kidblog.org and screencast-o-matic for my multimedia project.  I had to redo the project because I couldn't find where I put it online.  When you watch the video, you will see that kidblog is very similar to blogger (the blogs we use in class).  I really like using kidblog.  I think it is for elementary students, but I would like to use something similar for high school math students.  I think they would benefit from typing or writing about the process of math.  There is no writing in math, I see only problems being solved.  I would like to incorporate some sort of writing or blogging in my course in the future.
