Objectives: ① Combining with real life, we can understand the schedules of work and rest in different areas, look at the schedules and get the necessary information from them. (2) Be able to make a timetable independently and master the basic methods of making a timetable.
Point: Use the 24-hour timing method to calculate the time taken to solve the problem.
Difficulties: Make a reasonable timetable independently.
Breakthrough: observe the characteristics of the timetable and find out how to make it.
I. 24-hour timing mode:
One day =24 hours (twice clockwise)-the first lap: from 12 pm to12pm; The second lap: noon 12 to afternoon 12.
At midnight 12 =0.
Second, the formula:
End Time-Start Time = Elapsed Time
End Time-Elapsed Time = Start Time
Start Time+Elapsed Time = End Time
