For the most part, half-days seem to be a weird balance of fulfilling a requirement to be in school and just a waste. I only remember having them the day before holiday breaks. In those cases it's easy to attribute the rambunctiousness to the excitement over the break. But really it's hard to get anything accomplished on days when students are just excited to get out. The question, "how much time is left?" is asked triple the normal frequency. Classes are still long enough that I feel like we should be able to do something, but focus flies away.
I wish I knew what happened yesterday. Because they worked. I left school feeling better than I had on Tuesday.
Of course, school's been canceled today due to snow. (Which I prefer to going in and being dismissed at 10. If half-days are usually bad, days when we know we're getting out but don't know when are INSANE.) My frustration with trying to plan lessons in this situation continues.
