Third graders learn to figure out how much time has passed between a start and an end, counting up in hours and minutes, and check what they know with real schedule examples.
Students will be able to…
A show starts at 4:00 and ends at 5:30, but nobody says how long it ran. How do you figure out the amount of time that has passed?
Project this and answer each question about finding how much time has passed — read the explanation after each one.
