You might like to join the New Teachers Making The Grade group as it is maintained by a wonderful mentor with many years of teaching experience, Lynne Hoffman, who will be giving many tips for creating a positive/encouraging classroom environment. I'd leave this discussion run here too for now in the Verizon Thinkfinity 101 space, as you may get some good responses from the general membership too.
First remember to breathe!
Next, do some online searches and you will collect some wonderful ideas. Everyone is a bit different and you have to find a few folks of similar thinking to you.
Then, I suggest you join Twitter and religiously follow the hashtag #kinderchat. Follow everyone who responds in those conversations.
Next, add Pinterest to your daily searches. I curate a couple of topics there but there are loads of collections.
There are other groups online but I don't use them. Facebook, Tumblr, FourSquare to name a few.
Learn everything you can about your students ahead of time. I will call all of the parents before school begins. I will ask them about their children and see if there is anything they want me to know that wasn't on the school forms. I will also try to speak with the child during that call to help them connect. It eases their worries to know I care about them.
I have emailed all the parents I can as well and plan to have some play dates at the school playground for 1 hour each week before school begins. That way they can make friends and ask questions before school starts.
Never be afraid to say you don't know something and/or need help. You are not alone. We have all been there and can offer suggestions. Making connections and building trust are critical when establishing your classroom. The children will not be "available" to learn until they can relax and pay attention a bit.
