Discover the mean from fair share to the balance point. The lesson plan takes small groups of pupils through two different interpretations of the mean, the fair share understanding of the mean, and the balance point. Scholars use the interpretations to look at variability by using the number of moves to make it fair and the mean absolute deviation from the balance point. At the end of each interpretation, the groups come together to summarize their findings and share the group's work.
