The Division Unit involves identifying a variety of models to represent the process of division in order to learn how to use it to solve problems. Questions to answer may include:
- How do division situations differ from subtraction situations?
- How do equal-sized groups model division situations in the world outside the classroom? What real-world examples can you think of in which equal-sized groups model division?
- How do arrays and area models represent division situations in the world outside the classroom? What real-world examples can you think of in which arrays can be used to solve division problems?
- What happens if there are leftovers when using division?
- Given a division equation, how can you create a situation to match it?
