Question 1: Constructed-Response
There are 720 students at a school. All the students at the school are going on a field trip to a science museum. The students will ride school buses to the museum. Each bus holds 60 students when completely full.

#### Part A

What is the least number of buses needed to take all the students from the school to the science museum? Show or explain how you got your answer.

Enter your answer and your work or explanation in the space provided.

#### Part B

Write an equation to represent the problem you solved in Part A.

Enter your equation in the space provided. Enter only your equation.

#### Part C

The school can also use smaller buses to take the students to the museum. Each smaller bus holds 50 students when completely full.

What is the least number of smaller buses needed to take all the students from the school to the science museum? Show or explain how you got your answer.

Enter your answer and your work or explanation in the space provided.

### Scoring Guide and Sample Student WorkSelect a score point in the table below to view the sample student response.

ScoreDescription
4 The student response demonstrates an exemplary understanding of the Number and Operations in Base Ten concepts involved in finding whole-number quotients of whole numbers with up to 4-digit dividends and 2-digit divisors and illustrating and explaining the calculations by using equations. The student writes a division equation and uses division to find and justify solutions to a real-world problem.
4
3 The student response demonstrates a good understanding of the Number and Operations in Base Ten concepts involved in finding whole-number quotients of whole numbers with up to 4-digit dividends and 2-digit divisors and illustrating and explaining the calculations by using equations. Although there is significant evidence that the student was able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result the response merits 3 points.
2 The student response demonstrates a fair understanding of the Number and Operations in Base Ten concepts involved in finding whole-number quotients of whole numbers with up to 4-digit dividends and 2-digit divisors and illustrating and explaining calculations by using equations. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points.
1 The student response demonstrates a minimal understanding of the Number and Operations in Base Ten concepts involved in finding whole-number quotients of whole numbers with up to 4-digit dividends and 2-digit divisors and illustrating and explaining the calculations by using equations.
0 The student response contains insufficient evidence of an understanding of the Number and Operations in Base Ten concepts involved in finding whole-number quotients of whole numbers with up to 4-digit dividends and 2-digit divisors and illustrating and explaining the calculations by using equations to merit any points.
