OVERWHELMED WITH IDEAS!! I have all three of these activities saved in hopes to use them... but they are all very similar. If you use them in your classroom, would you just focus on one or more than one? I love boggle because the students have to come up with various words using 16 letters. With million dollar word and word within a word the goal is to come up with the "main word" and then smaller words. They all cover the same objective in very similar ways, and I would love to have my students do all, but I'm afraid they would get bored with it after a while and not put as much effort into it.
