Memory Game

I'm working on memorization of "If I Listen with My Heart."  One of my memory activities is to write the entire song on the chalk or white board.  We sing it through.  Then I erase a couple of words or a phrase or line and then sing it again.  Depending on the time, I erase two or more phrases at a time or just a few words.  We sing it all the way through after each time something is erased.  By the end of singing time the song will be totally erased and should be memorized.  I like to sing it for the closing song to "seal" it in their brains.
