From: Loyd To: Teacher2Teacher Public Discussion Date: 2001071606:49:59 Subject: Re: teaching time This is often a difficult topic to teach. The two main problems seems to be: 1. When borrowing an hour from the hour column, the student tries to cange the one hour to 10 minutes vice 50 minutes. Also when adding and the minutes add to 60 or more the student has problems converting to hours. 2. The other problem is finding elapsed time 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 comberson problem was to work it in two parts. Find the time from the morning time to the noon time and from noon to the evening time. Now, I use universal time for the most part.
