Question 21. a. Student gives correct answer and shows work: 546 quarts of strawberries b. Student gives an accurate explanation: Sample explanation: A method I could use to check my answer is to multiply the quotient by the divisor given in the problem. If the product of these two is equal to the original dividend then I know my answer is correct. c. Student accurately shows work to prove answer is correct: Sample response: 546 x 5 = 2,730 original number of quarts of strawberries 4.NBT.6 22. a. Student gives correct answers: Answers may vary. Correct responses will have four digits and a 7 in the tens place. Ex.: 3,971 and 2,573 b. Student gives accurate explanation. Answers will depend on the strategy used by the student. Sample explanation: The 7 in Patty’s number is in the hundreds place and the 7 in Matilda’s number is in the tens place. I know that the 7 in Matilda’s number is worth ten times less than in Patty’s number because of the place value of the number. Place values increase 10 times with each move to the left, and decrease 10 times with each move to the right. The tens place is one place value to the right of the hundreds place. Another way to see that the 7 in Matilda’s numbers are valued ten times less than in Patty’s number is by writing the numbers in expanded form. The expanded form of Patty’s number is 5000 + 700 + 50 + 2, and the expanded form of one of Matilda’s numbers is 3000 + 900 + 70 + 1. When comparing the value of the 7 in both numbers, we compare 700 and 70. 700 is ten times greater than 70, and 70 is ten times less than 700.

4.NBT.1 23. a. Student gives correct answer and shows work: Amelia drove 89 miles on the last day of her road trip. b. Student gives an accurate explanation: From the problem I was able to get information that helped me develop a strategy to solve the problem. The words “four times as many” told me that I would be comparing quantities. The total number of miles that Amelia drove on the first day of her trip was one of the quantities to be compared. I knew that she drove 4 times as many miles on the first day than on the last day, I need to figure out what number of miles times four would equal the total number of miles she drove on the first day. To do this, I needed to divide 356 miles by 4. 4.OA.3
