This task includes three different problem types using the 'Add To' context with a discrete quantity; see '1.OA The Pet Snake' for an 'Add To' problem with a continuous quantity. Table in the glossary of the CCSSM offers a succinct overview of all addition and subtraction problem types. Although students should experience and practice with all three problem types, they would not necessarily be introduced at the same time.
