Grades 3, 4, and 5 have their annual field day together. Each grade level is given 16 gallons of water.
If there are a total of 350 students, will there be enough water for each student to have 2 cups?

Yes.

Step-by-step explanation:

To solve this problem, students must see that each grade level is given 16 gallons of water—or a total of

48 gallons—for field day. Students may choose to convert across two or even three units going from gallons

to quarts and quarts to cups as shown in Solution B. Sharing multiple solution strategies can show students

the efficiency of using the rules learned in Topic A for converting. Solution A shows the use of the rules by

multiplying the number of gallons by 16 to find the number of cups. Comparing the number of cups needed

(700 cups) to the number of cups they have for field day (768 cups) allows students to see that they do have

enough water for each student to have 2 cups. Alternatively, Solution B divided to find the total number of

students who could drink 2 cups of water from 16 gallons of water, proving there is enough water.
