Changing a Lesson Plan

I have edited a lesson plan on Music and Other cultures. I changed 3 things:
1. Students would listen to 6 examples instead of 2

2. Students would travel to all different listening stations in the classroom instead of travelling to none.

3. tudents would create charts that would compare and contrast the different cultures

I feel that students should have the opportunity to be exposed to as much as possible. Hopefully this lesson plan will work for its original creator.
