Roll Around the Clock

Roll Around the Clock is a context from the Investigations book Name that Portion.

Students are solving fraction addition problems by using the clock as a model. This model is helpful when working with fractions involving 1/3, 1/6, and 1/12.  

In order to solve some of the addition problems, students need to find a common denominator (6 or 12) to support with solving the problem.  This experience also reinforces the relationship of equivalent fractions and representing a fraction in the lowest term.
