Compare Beethoven's fifth symphony to latin music and disco. Learners will listen to and discuss the elements found in the first part of Beethoven's composition. They'll then look for the same elements in Tito Puente and Bee Gees songs. They'll discuss that while the elements have changed they are essentially the same; they'll compare that to the concept of converting fractions to decimals and percents. The lesson is a bit heavy-handed but with a minor adjustment it could make for an interesting experience.
