I'm forever buying books of songs to use in my Kindergarten class. Most, I find, I already know and have used them to death.. Standard "Kindergarten Songs" are 4 liners which don't give kids credit for what they are musically capable of.. So I write most of the songs I use. And I use a lot of traditional folk music. What songs have you found which kids love to sing. That's the key - What do they love to sing. Kids do love singing.
