Actually, I don't see very well and didn't think I needed to spell check. Here is the message again (I also changed 50 to 60 in two places): This is often a difficult topic to teach. The two main problems seem to be: 1. When borrowing an hour from the hour column, the student tries to change the one hour to 10 minutes vice 60 minutes. Also when adding and the minutes add to 60 or more the student has problems converting to hours. 2. The other problem in finding elapsed time is when one time is in the morning and the other time is in the afternoon. Universal time or military time is useful here. Just add 12 hours to the afternoon time and the problem is easier. The way I was taught this combersome problem, was to work it in two parts. Find the elasped time from the morning time to the noon time and from noon to the evening time. Then add the two times together. Now, I use universal time for the most part.
