Fractions in the Fast Lane (except it's just fractions)

Every student has to do homework at some point, and every student at some point just wants to be done with their homework. But unlike what I imagine other students do, when I am in a rush to be done with my homework, I actually end up doing extra work. I want to know how much homework I have left, and how long it will take me, so I use math to figure that out. I count the number of pages in my history textbook that I have to read, and add the fractions of the pages. .25 + .5 + 4 pages = 4.75 pages more to read. I figure out how many math problems I have to do, then how many parts there are in each question, and then I can figure out how the fraction of the homework that I have done, and what fraction more I have to do. I also look at how many subjects I have homework to do for a night, and then assuming that I have the same amount of homework in each subject, I figure out what percentage done I am with my total homework.

In addition to fractions, I figure out at what rate I am doing my homework for a certain subject, or I know my typical rate from past assignments, and so then I can figure out about how much homework to expect. For example: if I am reading a page every 2 minutes, and I have 4.5 more pages to read, I can figure out that I'll be working for about nine more minutes (assuming I don't get distracted again doing math to figure out what fraction of my homework I still have to do).

Really, doing this math is a hindrance to my homework, and I end up doing extra math trying to figure out how much math homework I still have to do, but it helps keep my mental math skills sharp.
