Haiku Posted December 8, 2011 Share Posted December 8, 2011 (edited) Did anyone else find some of the problems in the Time Units chapter to be rendonkulous and nitpicky? For example, in one problem the student is supposed to find out how many days are in a century ... but the answer varies depending on what year you start with, and the student is supposed to use this complicated set of rules to determine whether a year is a leap year. Nowhere could we find an explanation of why the year 2100 will not be a leap year, even though there is a leap year 4 years before and 4 years after. We know the rule, but we don't know why a leap year would be skipped. I also don't like that she gives instructions to include the beginning date when counting how many days are from one date to another date. For example, if I were to give the number of days from today (12/8) to next Thursday, I would say 7. The MM author's answer would be 8. I was always taught not to include the starting date. Then her rule of including the starting dates doesn't hold true when calculating elapsed time in hours and minutes. 2 1/2 hours after 3:40 is 6:10, according to her answer key (and my calculations), but according to her "include the starting date/time" rule it would be 6:09. Dd worked on these problems for over an hour and was in tears. I finally told her to forget it because they seemed needlessly complex. Am I the only one? FWIW, I got all the "How much time has passed?" questions wrong because I didn't include the starting date.
