Students may be the greatest resource the teacher has for this project. Many students probably already have some kind of musical training. They can explain concepts to the class or show the others how a rhythm works on the instruments they play. Other teachers and people from the community can also be helpful in integrating this material into the classroom. The teacher might consider inviting the band instructor, cast from local dance productions, drummers in local bands, choir masters from area churches, and similar experts to help with these classes.
Most students have an intuitive understanding of music and rhythm.
The teacher's goal is to help them use that understanding to form a bridge to unfamiliar material in mathematics. Start with something they already understand - clapping their own hands. Young children are used to clapping in the classroom. Begin by clapping with and for the children in a very simple pattern like four equal and fast beats. Ask the students if they can repeat this pattern.
