Engage young mathematicians in learning about fractions with this cross-curricular math and music lesson plan. After listening to and repeating different beat patterns, children realize that musical notes are just another way of representing fractions, with every measure adding up to equal one. This understanding is then used to create patterns that are equivalent to examples provided by the teacher. Consider passing out simple percussion instruments to the class and turning math equations into music. A fun lesson plan that provides children with an unconventional context for developing an understanding of fractions.
