I love wordle. I am actually using this right now in my classes. We have been creating a heartmap in preparation for writing a memoir. The students have created a list of things that are important to them and we created a wordle to put on one side of the heart and then they will illustrate the other side. I plan to start the year out with this next year and they can use the heartmap all year as a place to generate ideas for writing. I did create one, but it does not save once you leave the site, so the link is just to the site.
