Here are my basic

*low-end*assumptions:

- A teacher has about
**100 students**(imagine 4 classes of 25 students each). These days, many teachers teach 5 classes of 30 each. Some pampered private school teachers (like I was) teach 4 classes of 15 students each. Still, 100 is a reasonable estimate and a nice round number. - Each student hands in
**one page to be graded each day**. This will likely be a single sheet of homework. This excludes any tests or quizes, which are generally longer than a sheet, so this is definitely a low-end estimate. - Each page takes the teacher
**1 minute to grade**. Again, this sounds like a short time to me if you're actually grading the work. And if you also consider the time it takes to determine the full-page grade and enter it into the computer system...

These estimates lead to a need to grade 500 pages per week, which I'm estimating could take 500 minutes. That's 8.33 hours, or

**a full work day**. Yes, a teacher could easily spend

**a full work day each week**

*just*grading. I find that astonishing.
