I have a draft about a website called Wordle that I was planning on posting next week. However, I found a much better post about Wordle that also has a fun lesson plan. The post called Wordle: Using Word Clouds in a Lesson comes from one of my favorite blogs called Box of Tricks. I highly recommend that you subscribe to the blog. In his post, José describes how he uses an interactive whiteboard to help with the lesson.
I am so excited to about this post. I have found a great application called Grammar Ninja that really works great with the SMART Board interactive whiteboard. This would be a great game to introduce to your students because it was developed by Greg Lieberman who developed the game as part of High School Independent Study Program in Videogame Design.
