I use Flocabulary at the college level as the basis of an assignment on the Sonnets. I give every student a sonnet to memorize. Iambic pentameter is perfect for rapping. I have two CD's with rap beats I leave on reserve in our library. The students must either make a video of themselves, an audio, or do a live performance of themselves rapping the sonnet I assigned them for the class; then, they must teach it having done some research and having prepared a bibliography. I give them the choice of making a video or audio since many are too self-conscious to perform live, but everyone has to do the assignment; we have a lot of fun. I hope you find flocabulary useful. I think it's a great resource for 6th grade and up (but I know it's ideal for high school for certain). I didn't know where else to post this so all of you would see it, so I put it here! Thanks!
