Some ideas on what to do with wordle from PBworks Certified Educators:

• Try using it as a prediction activity before reading
• I used it for the ISTE Student Nets. One of the things I'm working on this summer is designing a new year long tech class for 8th graders. One of the things I really like about Wordle is how it can help you see points of emphasis.
• An unexpected benefit of creating a Wordle is that many times when I examine my Wordle I will see words that I can replace with synonyms to make my document clearer and more concise.
