Do These Add Up?

Illustrative MathematicsVaries

This task addresses common errors that students make when adding fractions. It is very important for students to recognize that they only add fractions when the fractions refer to the same whole, and also when the factions of the whole being added do not overlap. While these questions could be approached as separate tasks, here the idea is to sort out the appropriate operation in problems that are superficially alike but may differ mathematically. This set of questions is designed to enhance a student's understanding of when it is and is not appropriate to add fractions.
