I have been playing with Wordle and Tagxedo. What a great activity! I had so much fun. I can imagine that students will love this. Wordle is very easy to use. You simple copy and paste your text, and then you can play with the font, color, and layout. Tagxedo allows the user to create a custom shaped Wordle design. It is not as user friendly as Wordle, but with a little bit of playing, I was able to create a baseball-shaped Tagxedo using my son's report on his team's run in the playoffs a couple of years ago. The best part was that I had a great time creating my designs.
