From the Elementary Teacher Resources blog:
1) Dr. Jean - Kiss Your Brain!
Dr. Jean's Kiss Your Brain! CD is one of my favorites because it has "The Alphabet's In My Mouth" on it (see video).
This CD also has "Who Let the Letters Out?" My students go wild for this song! They love to "rap" the sounds and dance around.
But... if you're looking for a great song about friendship, you can't pass up "Twinkle Friends". Every time my kids and I sing this song I'm just about brought to tears. It is just perfect for building a classroom community!
