But along with greetings and introductions, going over routines is also important! That's why before we enter the classroom, I always pause at the door, and tell them what to do when they enter the classroom. I let them know that those directions are written on the board in case they forgot any. Then I let them enter 4 at a time, to stagger the wandering/desk finding.
Having a repeat of those directions written on the board is useful. Highlight key information, for those fourth graders who aren't proficient in reading and following multi-step directions.
Reading a lot of text off the board early in the year can be tricky, which is why I tell them verbally first. Watch for who is helping their peers, and who are looking lost. Just keep in mind that not all shell shocked fourth graders stay that way year round. Some have more difficulty with a new context.
I give parents a copy of my expectations and behavior policies as well.
What does your first day morning routine look like?
