This document contains 12 blank homework calendars, one for each month of the year. Each has the days of the week (Monday-Friday) in Spanish and "calendario de tarea" with the month in Spanish at the top.
I use this in class as a way for students to log homework assignments. They keep this calendar in the binder, and when I walk around to check off the homework, I stamp their calendar. Every two weeks, I collect the calendars and update the grades. Every month, I print off a new homework calendar for the new month.
This is a great tool that allows the teacher to quickly check homework while providing students with a visual aid that helps them track how much homework they have completed. It avoids the "but I'm sure I did it" debate because the student can clearly see how many homework assignments he or she completed.
