The only trouble they had was making important words bigger, connecting phrases, and revising. I showed them how to make words bigger, type the word a lot, and how to connect words, add a ~ between words. Most students were able to make the more important words larger but only a few were able to connect phrase. I was unable to show them how to revise their poster and told them they needed to reenter their words.
I could also see using Wordle to make theme posters for books, character posters, Social Studies content posters and Science concept posters. Here's a link I created for gravity. I'm not sure how that link works. It doesn't appear you can search for terms. I can't paste a copy of the image either.
