I looked up on youtube and teachertube and took forever to play. I lost sight of what I was really suppose to be doing. I had even walked away for a moment to do some chores and when I came back, my youngest had a Justin Bieber video playing on my computer. This is obviously a great area to visit for all people. My children then showed me some other things that I had no idea were on these sites. They had fun "teaching" mom. I was impressed that even my 9 year old new so much. I thought I had failed her and she showed me. This definitely stand out as a fun activity that I really enjoyed. I pulled up under the teachertube this particular video on student centered classrooms as this was a huge deal in Cy-fair and seems to be the wave of education today.
