### Standards & Objectives

Essential and guiding questions:
• How are these strategies similar and different?
• Where did you see the numbers in your equaation in the model?
• The first strategy used the relationship between multiplication and division to find the solution. What is the relationship between multiplication and division? Will this strategy work all the time? Explain.
• What do you notice about the product and the dividend? Why are they the same in this problem?
• The second strategy started with 8 x 10 in order to figure out 72 divided by 8. Will this strategy work on all multiplication/division problems?
• The third strategy used the partition model to solve the problem. How is breaking the rectangle apart helpful in solving the problem? Is it possible to partition (break apart) either factor or both? Explain your thinking.
• Which of these strategies work on all multiplication/division problems?
• When do you use multiplication to solve a problem? When do you use division to solve a problem?
