Count Down to the End of the School Year

Now that we are into the second week of May, summer vacation doesn't seem so far away anymore. My daughter's math teacher has counted down the days since day one. Last week, I substituted for a 5th grade teacher who has a great twist on counting down the days. On the first day of school he represents the day as 1/180, the second day is 2/180 or reducible to 1/90, and so on. Each day the students calculate the fraction of the school year completed. Mr. M. has each of the fractions listed on the wall. Today was the 151st day of the year, as a fraction of the total it is 151/180 and is not reducible. Great way to build math skills!
