Page Text: Movie Times
My youngest daughter was in shock when she saw that the description of the Netflix movie listing show 105 minutes. To her, it seemed like a long time. I asked her a simple comparison question that lends itself to making an inference on facts. I said, “If two hours is 120 minutes, then what can we say about the movie you want to see?” I was hoping she would say it was less then two hours long. I didn’t actually want her to calculate the exact time by using unit conversion or anything like that. My 15-year-old daughter was eager to answer. “I know, I know!” I gave the younger one time to answer, and she was trying to add or subtract who knows what. Well, when a few minutes go by, I let the older answer, and she says one hour and forty-five minutes. I gathered that she did the unit conversion in her head and figured it out. An hour is sixty minutes and one hundred and five is forty-five minutes more than an hour.
So the goal I had in mind was for her to compare one hundred and five to one hundred and twenty to realize that the movie was not as long and she thought it was (five hours she guessed). I helped the little one understand that since 120 is greater the 105, than the movie was going to be less than two hours long
