Evidence Statement 4.C.6-1 Present solutions to multi-step problems in the form of valid chains of reasoning, using symbols such as equals signs appropriately (for example, rubrics award less than full credit for the presence of nonsense statements such as 1 + 4 = 5 + 7 = 12, even if the final answer is correct), or identify or describe errors in solutions to multi-step problems and present corrected solutions. Content Scope: Knowledge and skills articulated in 4.OA.3
The Rodriguez family is vacationing at the Inner Harbor for the week. Dad, Mom, Maria, and Juan want to rent electric scooters, but Dad doesn't want to spend more than $250.00. Scooter rentals are $6 an hour and have a limit of 4 hours a day.
How many full days can the whole family rent scooters?
Write explanation, answers, and equations in the space provided.
With the remaining money, can just Maria and Juan ride scooters for another full day?
Explain your reasoning that determines if Maria and Juan can rent scooters another day.
Part A= 2 points
Student response includes the following 2 elements
Reasoning Component= 1 point
o Student provides a valid explanation of how to find the number of days the family of four can rent scooters within the $250.00 limit. ( 2 days with remainder of $58.00)
Computation Component-= 1 point
Student provides the correct number of days the family can rent the scooters (2)
Sample Student Response:
I would find the number of days the family can rent scooters by first finding the amount it would cost one person. Then I multiply that answer by 4 to find the cost of the scooters for 1 day for the whole family. Then I would divide the amount Dad wants to spend by the amount of one day for the whole family
$6.00 x 4 = $24.00 (Cost of scooter rentals for 1 day for 1 person)
$24.00 x 4 people = $96.00 (Cost of scooter rentals for 1 day for family of 4)
$250.00 ÷96.00 = 2 days remainder of $58.00 (Number of days family of 4 can rent scooters)
Student response includes 1 of the 2 elements.
Invalid or incorrect responses
Part B Total Points 1
Reasoning = 1 point
o Student provides the correct reasoning that Juan and Maria can ride scooters for another full day.
Sample Student Response
There was $58.00 left in Dad’s budget. It would cost $48.00 if only Maria and Juan rent scooters
$6.00 x 4 hours= $24.00
$24.00 x 2 (Juan and Maria) = $48.00
