Book of Mormon color sing

I taught the song, "The Books in the Book of Mormon" on sunday and used 2 methods. First, i had them open their BofM to the table of contents and we sang the song with everyone following along in their scriptures. (i wanted them to get familiar with the table of contents)After a few rounds of that, we put the scriptures away and sang to my second method. I saw this idea on www.bellaonline.com. It was such a hit-who knew the kids would have so much fun with it! I wrote the books in the book of mormon on a posterboard rotating color every couple words. (i used red and blue) I assigned 1/2 the primary to be red, the other 1/2 was blue. When it was their color, they had to stand and sing. Everyone sang the parts that were written in both red and blue. They got a great workout standing up/down and learned a new song at the same time.
