I feel your pain!
Our spring break isn't until like April 10th-ish. I get annoyed being there too, and I have definitely noticed that the kids are much needier than usual. And the other day, for the first time, the whole class was complaining that I didn't give them enough time to study for something (it was really simple - 21 pronouns. All afternoon and evening and some time the next morning to study.) I felt very frustrated. However, I know to chalk a lot of it up to spring fever. I don't know of any other career where a professional is required to interact almost constantly with the same group of people for 7-8 hours a day and still keep their sanity. That's why we feel the need for breaks so keenly. Anyway, here are some things that I'm doing to preserve morale (both for myself and my 6th grade munchkins)
(1) Several class periods outside every week. We are blessed with a very tranquil campus with lots of free space (big field, trees, etc.), so we often go outside for history, science, Bible, or reading. At least a few times a week.
(2) Lunch outside every chance we get
(3) Try to maximize use of time to allow more time for free play at the end of the day. They're in 6th grade, but they still love recess, if only for the chance to socialize.
(4) A few weeks ago, I promised them a walk to a local park (it's about a 15-minute walk) and time to play from 1:00-2:30 if they had the whole week's work done by Friday at 1:00. I've NEVER seen them work so diligently.
(5) Get with some colleagues and find a way to do something fun for a day. We recently had dress-up day for the teachers. Some came in formals (great way to use those old bridesmaid dresses), or just Sunday church clothes. We didn't tell the principal or the kids that we were going to do it. We just did it.
(6) Go all out for holidays. St. Pat's is coming up. Do something funky. Copy off all work for the day on green paper, have the kids bring green snacks, etc.
They're as ill with school as we are, as hard as that is to believe, and making their lives more interesting in turn makes yours easier. Hope this helps!
(PS~ These things certainly haven't solved all my problems to be sure, but they are certainly bright spots in otherwise relentlessly long weeks!)
Blessings!
