How I Use It
I have used Wordle mostly with assignments where students have read a book and needed to describe the main character, etc. It is also a good tool to use to help children understand using "Tags" in Internet Technology and what they are.
My students from 1st through 8th grade have used Wordle for several assignments. One downfall is that you can't "save" your project in Wordle, which can be a problem if you are a Specials Teacher like I am and don't have time to go through the edit spelling errors with each child within one short class period.
