LESSON 2 Modeling Division
Grace collected 664 rocks at the beach. She wants to divide the rocks equally among four friends and herself. How many rocks should Grace put into each cup?
- Write Grace's problem as a division problem.
- How many rocks should Grace 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?
Grace 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.
