Two groups of jelly beans. They might say that there are 5 more red ones than green.
They might say they need 5 green ones to make them the same amount as red.
Very important to think through the problem structures. In U.S. the standards include a chart of the various structures in addition and subtraction and students need to have exposure to and experience with ALL of these. The expectation is that they will “master” all of them by the end of Grade 2. Important to connect the problem structure with the models and ways to represent as well. I find that too often the curriculum writers get caught up in the story/context of the problem and don’t vary the structures enough to expose students to the wide range of types.
