LESSON 3 Modeling Division
Jackie collected 87 colored rocks at the beach. She wants to divide the rocks equally among four friends and herself. How many rocks should Jackie put into each cup?
- Write Jackie's problem as a division problem.
- How many rocks should Jackie put into each of the five cups? Show or tell how you know. Draw a picture.
- Are any rocks left over after dividing them among the five cups?
- How can you check that your answer is reasonable?
Jackie starts to put rocks into each cup one at a time. Then she decides it will be easier if she first figures out how many to put in each cup. She draws a diagram to help her solve the problem.
