It's that time of year again! You wake up in a sweat, shaken from the dream where your clock doesn't go off and you are late. You know what I'm referring to -- "The First Day of School!" Whether veteran or rookie, we all have mixed feelings of excitement and fear about that day.

Thank goodness, it's never as bad as it is in your dreams. My last 28 "first day of school" experiences have been pretty good. As a matter of fact, like a good wine, they have only become better with age.

You probably know that saying, "You only have one chance to make a first impression." Well, you only get one "first day of school." Of course, if you don't do well on the first day, that does not mean you should quit teaching. With that said, here are seven tips to help make a good first impression on that first day.

1. Smile

Guess what? You can even laugh if you want. Hopefully that myth, "Don't smilebefore December," has been laid to rest. It's OK to let your students know that you are human and have emotions.

2. Dress Up (optional)

I am an old-fashioned type of gal, and my girlfriend teases me mercilessly. But I go out and buy a "first day of school" outfit. I guess it's because I remember my first day of school outfits from my youth. Nothing wrong with looking good on the first day!

3. Be Prepared: It's the Little Things

Don't wait until the students walk into the room to make important decisions that could lead to chaos. Simple things become complicated when you are dealing with 20+ students entering your room for the first time. How are you going to seat your students? A seating chart is a good idea until you get to know your kids. How are you going to distribute all those notices that need to go home? A class mailbox works wonders! How do they go to the bathroom?Signals are a great way to get your attention without disruption. How will they line up when it is time to leave the classroom? Try and think all of these "little things" prior to the first day. If you are new, ask a veteran teacher for help.

4. Develop Expectations

Whatever you choose to call it -- expectations, rules or norms -- make sure you develop them on the first day. Your students need to know what is expected of them from day one. Whether you prefer creating the rules or letting the students develop them, make that part of your first day. Last year, I had my students create the rules, and then create posters on the computer with illustrations depicting each rule. I laminated them and hung them in the room for the entire year.

5. Classroom Management

The first few days are considered the honeymoon period. But sometimes there is no honeymoon. What do you do then? Make sure you have an idea on how you might handle a situation. Set up a buddy teacher in advance. Try using online behavior management tools. My district has moved toward theResponsive Classroom approach, so I will make sure that I'm familiar with it before my students enter my room. Make sure you have a system in place.

6. Have a Plan for the Day

The first day of school is a long day -- teachers and students need to adjust to being back in the classroom. Think about what you are going to do with the day. Most teachers spend the day on rules (norms), routines and icebreakers. Some prefer to stick in lessons. You can do both. Choose a picture book to share that will lead to discussions about issues important to your classroom. Try some "Getting to Know You" activities to start building a family atmosphere. Give students a chance to explore the classroom. If you integrate technology in your classroom, the first day is a perfect day to introduce digital citizenship.

Make this a day to learn about your students, and give your students a chance to learn about you.

7. Don't Judge/Clean Slate

You might have witnessed negative behavior from a particular student last year. Maybe the teacher from last year cornered you and gave you an earful about this child. No matter what, give that student a clean slate, a chance to start fresh. At the end of the school year, I got a note from a student who thanked me for sticking by him even though "he got on my nerves." If I had treated this child according to the behavior he had exhibited in previous years, he would have never have had the amazing year he ended up having. We all deserve a chance to start again.

The first day of school finally ends, and the rest of the year lies before you. Don't worry -- if you didn't "get it right" the first day, you still have many more days ahead of you to improve!
