Subject: teaching elapsed time
I use a T-chart to teach elapsed time. Make a T chart with a long horizontal line near the top of the T. Start with the beginning time on the far right side. Put a dash and then write what the time would be one hour from then (ex: 8:25 - 9:25 = 1 hour). Let's assume that the ending time is 11:46. Beneath 8:25 write 9:25 - 10:25 = 1 hour. Beneath 9:25 write 10:25 - 11:25 = 1 hour. Remember, all of this is lined up on a T-chart. I put the actual times on the right side and the calculated amount of time on the left side of the T-chart. Next, write 11:25 - 11:46 = 21 minutes. Draw a line beneath the hours and minutes so you can add them: ______________________________/___________________________________ / 8:25 - 9:25 / 1 hour 9:25 - 10:25 / 1 hour 10:25 - 11:25 / 1 hour 11:25 - 11:46 / 21 min. +________________ 3 hours 21 min. Hope this helps! Shirley P.S. If you have a good idea, please share it with me.
