First-year teacher "must-haves"

I will begin teaching for my first year in a 3rd grade classroom in about a month (yikes!) I was wondering if anyone could suggest any "first-year" teacher classroom must-haves to start the year out right...any feedback would be greatly appreciated!

Time to get back to it!

Yes, I know I have been absent in my writing for several months now. Admittedly, my semester of full-time student teaching has proved to take up the majority of the time. However, the end is on the horizon. This semester has, without a doubt, been the most challenging of my semesters at William and Mary, but also the most rewarding. My students always find a way to challenge me. Anyway, with that said, I am hoping to come back to blogging to document my first year of teaching.
