Time and Perimeter
* Can you convert units of measure for time and measurement? * Can you solve problems involving seconds, minutes, and hours? * Can you measure lines? * Can you draw lines of a certain length? * Can you solve problems involving the perimeter of geometric shapes?
Length/Perimeter:Time: 1 cm = ___mm1 min = ____ seconds 1 m = ____mm 1 hr= ____ seconds 1 m = _____ cm1 hr= ____ mins 1 km = ___m
* Helen starts an art project at 9:13:01am on Saturday. She finishes at 11:14:44 am. How long did she spend working on her project? * * Jaden rents “The Green Hornet” with his brother and starts watching it at 5:55:55pm. Its terrible. He decides to hop into his time machine so he can go back and have all the time back he wasted watching that awful movie. “The Green Hornet” is 119 minutes of absolute garbage. What time will Jaden have to go back to if he wants to never see this waste of $120 million?
