Routine or Schedule?

One of the benefits of homeschool is not having a strict schedule to follow.  I do however like a good routine so we don't get too far off schedule.  So far we are staying on track even if we have to do a little extra in the evening.  We love being able to get up and have a leisurely breakfast before we get started on our school day... and take a break to pick weeds from the garden or play outside (or chase chickens like yesterday lol).  We can take a long lunch and eat at DQ or at the park.  It's so nice!   Our basic routine is to get up and have breakfast and start school by 9:00.  I take turns working individually with each boy while the other is finishing up work or playing with the 2 little ones so they don't distract us.  We have lunch around noon then a little playtime.  After that is nap time for the little guys while we do our joint work (history/geography and science).  It took a few days for us to get this down but it is working great now. 

I'd like to know what you do.  Do you have a basic routine? Or a schedule?  Tell me about it! :)
