Elapsed Time Skill

We are working very hard on elapsed time right now!!!

Example:
Start: 11:45am
Stop: 12:15pm
Elapsed: 30 minutes

That problem could look one of three ways:
1) Start: 11:45am, Stop: 12:15pm, Elapsed: ?
Student only needs to figure how much time has passed and can count the time passed from the start to the stop.
This is the easiest of the three.



2) Start: 11:45am, Stop: ?, Elapsed: 30 minutes
Student must look at the starting time and add the elapsed time to get the stopping time.



3) Start: ?, Stop 12:15pm, Elapsed: 30 minutes
Student must 'take away' or count backwards from the stop time, using the elapsed time.
This is the most challenging of the three.
