Getting Nervous

Although I have been teaching for years, I am getting nervous. Im teaching 1st grade this yr, and I really don't know what to expect, and what to plan. First grade is one of the most important grades because it's sets the foundation for students, and I don't want to hinder any of my students educational success. I am used to teaching intermediate, and as you know they come to me reading already. I am not sure if I want to focus on literacy stations or word work centers only, I have to decide school starts Monday.
