Lower Elementary:
Question: There are 30 rows of passenger seats on an airplane. The seats in each row are labeled A, B, C, D, and E. How many passengers can the plane hold?
Solution:  If there are 30 rows of seats and there’s an A, B, C, D, and E seat in each row, then there are 30 A seats, 30 B seats, 30 C seats, 30 D seats, and 30 E seats. That means that there are 30 + 30 + 30 + 30 + 30 = 150 seats.

Upper Elementary:
Question: Amelia is taking a train to Chicago. The trip is 7 hours long, and the train travels a total of 560 miles. What is the rate of the train’s speed in miles per hour?
Solution:   To find the number of miles the train can travel per hour, we need to divide the number of miles by the number of hours: 560 miles ÷ 7 hours = 80 mph

Middle School:
Question: Jamie is filling the gas tank of his car. The tank holds 11 gallons of gas and is half full when Jamie pulls into the gas station. If he fills the tank completely and the gas costs \$2.988 (2 dollars, 98 cents, and 8 mills) per gallon, how much does Jamie spend on gas?
(Hint: The smallest unit of currency that a gas station can charge is a cent, so remember to round!)
