I am one of the fortunate teachers who has been using a SMART Board in my classroom for a few years now, and I am always asked, "Where do you come up with such interesting ideas? Where do I start looking for some ideas for my classes?" One site that I recommend and check on a regular basis is the SMARTBoard Lessons Podcast. Joan Badger and Ben Hazzard are the hosts of the informative podcast and each week, they have great tips and lessons. Check it out, I know you will get hooked on this podcast! An added bonus to this podcast is that they provide all links and lessons in notebook format as well as pdf if possible on their blog.
I love that they add free downloads to the music they use in the podcast!
