WInding down...or am I?

I have been working really hard lately trying to make my lesson plans as concrete as possible. I have found, contrary to what I have been told, that really good planning does not help that much with engagement or with behavior with my students. However, most recently, I have realized that really good lesson plans do promote better and more learning.
I have also been doing lots of different "fun" writing activities which have excited many of my students more than I have seen them before (in relation to their writing of course!)

However, I am getting tired and looking forward to the summer. I keep on thinking that if I feel this way, my students (who literally can't wait) are bursting at the seams for freedom. I am also worried about how my students are going to do this summer. I just know some of them are going to do something bad and all I can do is encourage and model healthy living.
