Alligator Bossa is a great piece for a concert or for those occasional times when a performance is needed for something like a PTO meeting. This cute little song is fun, easy, and teaches the students how to use the greater and less than signs in math. It is set in a bossa nova style which makes it quite rhythmic, but it is still reasonably attainable by 1st and 2nd graders. The bundle includes a lead sheet, a demo, and the performance track. This product is licensed to the original purchaser for one performance season; however, classroom use is permitted perpetually in one classroom. If this product is purchased by a school, then the license is specific to one classroom and the teacher who initiated the purchase.
