If you missed Part 1: Arrival, make sure to check it out!
If you have taught before, you know very well that the first few weeks of school are very heavy on routines and procedures! Our motto at my old school was "Go slow (now), to go fast (later)." The more time spent on setting expectations and practicing routines and procedures NOW will pay off immensely in the long run. That means that academics might start off slowly, but they will pick up later. If you don't take the time to practice routines and procedures, you will be losing even more time redirecting later. Go slow to go fast!
Here is a handy dandy list of routines and procedures you will need to teach in the first week of school. (Click the image to download a copy for FREE!)
The first column on the routines and procedures checklist are the things I recommend building in to your first day, and a few items on the second column as well. As I plan, I work these things into some fun activities, and spread the stand-alone procedures out (like bathroom and recess expectations and routines) in between activities. For example, if I'm planning to do an All About Me activity where students will be writing about their favorite things, I will first model how to properly use and take care of pencils before students are given this material. The activity will then give students the opportunity to practice what I've modeled. After this activity I might take some time to introduce our procedure for going to the bathroom, and have students practice this procedure. Our next activity might involve using crayons, so I would do another model of proper use of crayons. You get the picture. Real application of the routines and procedures; thoughtful planning of how to incorporate them into your day. (**I explained how I make this work for my arrival activity in the comments section below!**)
For some of these things, you will need to re-teach multiple times over multiple days and/or weeks before students are 100% ready to take on the routines and procedures on their own. They will need lots of repetition and lots of opportunities to practice the routines/procedures correctly. It will feel like Groundhog Day to you, but kids need it, and it will pay off, I promise.
Responsive Classroom has some great, highly effective strategies for teaching routines and procedures. I wrote about them and included some fabulous video examples here: http://www.happylittleheartsblog.com/2015/07/establishing-routines-and-procedures.html
Remember, this first day can set the tone for the whole year, and you do not want to lose the opportunity to start off on the right foot immediately. So, establish routines and procedures, and establish them well. You can have fun and still show your students that there is work to be done and there are expectations that are to be followed in order for that work to get done.
