Homework

I'm not a huge fan of homework.  I never have been!  I only give the students in my class homework once a week and thats to keep the parents happy.  I personally feel my students work hard all day and do enough during the day-  I would rather them be outside playing than sitting at the table for an hour working on a math problem.  Every Monday at the end of the day we have some "Ketchup Time", where each child is assigned a task they havent yet finished.  This being said, I am always up for a challenge and usually have some homework of my own each night.  Whether I am researching an answer, printing off new worksheets, buying items needed for the classroom from ebay or heading to the library the hours are endless, but always worth it!  What are your thoughts on homework?
