Here is a lesson for teaching the song Deep in the Heart of Texas

Getting kids to sing was easier because they had lots of fun clapping, but overall I'd say they only sang about half the time.

The doc file has a lyric fill in and a word search, in case you want to bring the singing to an end a little early.
The word search might not be totally useful because it has my name in it.

You can find links to a video with lyrics to the song in the lesson plan.
