Content-area learning is definetly enhanced with music. In any subject a long can make a topic come to life. Some of the greatest songs we learned as kids I still get asked to teach in my classroom. As a teacher it is our goal to encourage and engage each student with the use of one or all of the senses.
Simple songs can help anyone learn just about anything. How about using the hokey-pokey to teach left from right. Or the song about the 50 United States.... Just the other day I taught my kinder kiddos a song about manners. Another great source of songs.
