Wordle is an awesome tool that really engages students. I like to use it with vocabulary development (where students add synonyms and make the more impressive words larger), but you can use it in many ways.
Just make sure you go to Worlde.net not .com! Or you can just click on this link: Wordle
Example: A student’s Wordle for the word little. (The word little is on there, it is just too small to read it – ironic?)
