Our Summer Schedule:
Wake - 9:30am: Breakfast, AM Lists, Morning Jobs, then TV time (cartoons!)
9:30 - 11:30 am: Free Time or Outing (Library, Park, etc)
11:30 - 12:00pm: Lunch
12:00 - 1:30pm: Quiet Time
1:30 - 2:30pm: Free Time
2:30 - 3:30pm: Summer School
3:30 - 4:00pm: Cleaning Jobs
4:00 - 5:30pm: TV / Movie / Free time
6:00 - 8:00pm: Evening Jobs, PM Lists, Reading Time, Family Time
In the morning, the TV doesn't go on for cartoons till all the other items are completed. During the summer we do "Summer School" with our kids -- workbooks and activities to keep their minds sharp between the previous school year and the next. "Cleaning Jobs" are additional responsibilities that we give our children during the summer, and they change every day.
For details on what AM / PM Lists and Morning / Evening Jobs entail, see my post "Family Economic System: Chore Charts & Kid Bucks System."
This schedule is, of course, flexible. We're going to be going to the library once a week, and hoping to do a lot of in-town stay-cation-ing too. :)
Have a great summer!
