Haha. I had that exact same problem at the beginning of the month. With elapsed time, I was really encouraging the students to actually use the clock to figure it out, like the book teaches. Most kids got it, but I had| a couple who just didn't! I had a High School volunteer at the time who was working on elapsed time with one of my students, who taught him how to use addition and subtraction to figure it out. So if he was finding what time it will be in so many minutes, he added. (It is 12:30. What time will it be in 20 minutes? 12:30+:20=12:50) If he wanted to know how many minutes passed between | |
two times, he subtracted. (How much time passes between 1:45 and 1:57? 1:57-1:45=:12)
I really wanted to avoid that, since you run into problems that way, but it really, really helped the student who could not even begin to grasp the concept. It seemed the more I worked one on one with him the less he got it. At least now he has some idea of how to get the right answer, and hopefully the more he does it, the more he'll understand.
I'm not sure if that helped you, but that was my experience.
