Adventures of Teaching Math
Wordle is awesome! taking entire documents and creating a picture out of it using the commonly repeated words! I've had good discussions with people who dislike it because it doesn't really have any critical thinking value... but hey... it sure is pretty!
It would never even occur to me that Wordle could possibly have critical thinking value... (and I would never actually use it for math class) I just like it because it makes great visuals of vocabulary words. It is prettier and FASTER than anything I could do myself!
