Every bridge has a sign on its side listing its “clearance” – the bridge’s height above the road in inches and feet. Why? So we don’t have what happened in this picture! This truck tried to drive under a bridge even though it was too tall to fit. This is a case where doing the math could save the day.

*Wee ones:* Which is taller in that picture, the car on the left or the truck on the right?

*Little kids:* The truck got stuck at 2:00 pm, If it didn’t get un-stuck until 2 hours later, when did the truck finally roll free? *Bonus:* One way to get a truck un-stuck is to let the air out of all its tires. If the truck is an 18-wheeler and you’ve let the air out of just 1 tire, how many tires do you have left to do?

*Big kids:* If the bridge height was 11 feet 11 inches and the truck was 1 inch taller, how tall was the truck? (*Reminder if needed:* How many inches are in 1 foot?) *Bonus:* If that truck had a 36-mile trip, and the distance it had traveled so far was only 1/2 of what it had left, how far had it driven so far?

__Answers:__

*Wee ones:* The truck is taller.

*Little kids:* At 4:00 pm. *Bonus:* 17 wheels.

*Big kids:* 12 feet. *Bonus:* 12 miles. If the distance that’s left is double the distance traveled already, that’s the same as having 3 pieces all that length….and 36 divided by 3 is 12.
