I saw this site being used in a class the other day and I wanted to see if there were other videos/songs that could be used. I saw a nice free Energy Song that would be perfect for our 6th grade teachers who teach a lot of these concepts and I liked their game show Even/Odd video and Capitalization enough to send the link to our first and third grade teachers. The site is subscription based with a 14 day free trial. I wish you could test and buy individual songs as opposed to having a monthly subscription or buying an entire CD (when you only want one song). Most of the songs seem more middle/high school orientated. I wouldn't get a subscription if I was in the classroom (but I would certainly use the free songs if they applied!).
