DescriptionIn the fifth clip Michael and Brian extended their model using the orange and red train to show thirds and twelfths in addition to fourths. They showed that the difference between two thirds and three fourths was one twelfth, and repeated their justifications to a visitor and researcher Amy Martino on separate occasions.
