Students learn how to find a common denominator between two fractions and then add or subtract the fractions. They use visual representations to understand the decomposition of the larger of two fractions to find a common denominator with the smaller fraction. This program could be used to further your understanding of how you could use Python in the classroom, as a demonstration or discussion with your students, or as a way to introduce various CT concepts, such as pattern recognition or abstraction, to your students by inviting them to extend the existing functionality of the program.
