I had to add another post this week. I just read this on a blog and think it is fabulous – I had to share immediately! Smartteaching.org has a post on the 100 best You Tube videos for teachers. These are even arranged by subject with a short description. These could add that extra punch you are looking for in your lessons. Check it out.
Remember you can also download You Tube videos using Zamzar (one of my personal favorite tools!). There is a handout in our common drive if you need some refreshing. Enjoy!
