Five Things Great Teachers Do as the Students Are Entering the Classroom

The opening minutes of a class are not merely a transition between the hallway and instruction. They are an opportunity to establish relationships, assess students’ readiness, reinforce expectations, and create momentum for learning. Great teachers understand that a successful lesson often begins before the bell rings. While students are entering, these teachers are not seated behind a desk finishing paperwork. They are actively shaping the emotional and academic climate of the room.

1. They greet students personally

Great teachers position themselves at or near the doorway and acknowledge students as they arrive. Whenever possible, they use each student’s name, make eye contact, and offer a brief, authentic welcome.

This small practice communicates an important message: You belong here, and I am glad you came. It can also influence behavior. In one study, teacher greetings increased participating students’ average on-task behavior during the first 10 minutes of class from 45 percent to 72 percent. A later experimental study found that positive greetings improved academic engagement and reduced disruptive behavior.

The greeting need not be elaborate. Consistency and sincerity matter more than handshakes, elaborate routines, or scripted enthusiasm.

2. They read the room

An effective teacher’s greeting is also a quiet assessment. As students enter, great teachers notice who appears cheerful, anxious, tired, angry, withdrawn, or unusually energetic. They listen to the hallway conversations that spill into the room and watch how students interact.

This does not mean diagnosing every expression or publicly questioning a student who seems troubled. It means gathering information. A quiet “Are you doing all right?” or “Let’s check in later” may prevent a problem from escalating. Great teachers recognize that students do not leave their emotions, family concerns, or social conflicts at the classroom door.

3. They point students toward learning

Students should not have to ask, “What are we doing today?” Great teachers make the opening task visible, accessible, and worth beginning. A brief retrieval question, intriguing image, provocative quotation, error-analysis problem, or connection to the previous lesson can immediately direct attention toward learning.

The task is already displayed, required materials are available, and students know how to begin without waiting for lengthy instructions. This purposeful start protects instructional time while allowing the teacher to continue greeting students and handling individual needs.

A strong opening activity is not busywork. It awakens prior knowledge, generates curiosity, or provides the teacher with useful formative information.

4. They reinforce routines calmly

Great teachers do not begin every period by repeatedly correcting the entire class. Instead, they use proximity, brief prompts, and specific acknowledgment to reinforce established routines: “Thank you for getting started,” “You’ll need your notebook,” or “The opening question is on the screen.”

The Center on PBIS emphasizes creating predictable, positive, effective, and equitable classroom environments. Entrance routines contribute to that predictability. When expectations have been explicitly taught and consistently reinforced, students can enter, organize themselves, and begin working with increasing independence.

Calm consistency is more effective than starting class with irritation, threats, or a list of complaints.

5. They create an emotional bridge

Students often arrive carrying the energy of the cafeteria, hallway, previous class, or morning bus ride. Great teachers help them cross from that experience into a different kind of space.

They model the emotional tone they want students to adopt: calm, purposeful, respectful, and optimistic. They may offer a quick word of encouragement, acknowledge a student’s recent success, or briefly refer to something the student mentioned earlier. These small acts accumulate over time, strengthening trust and making later corrections, challenges, and feedback easier to accept.

The doorway is therefore more than an entrance. It is where classroom culture is renewed each day. Great teachers use those few minutes to see students, understand them, prepare them, and invite them into meaningful work. Long before the formal lesson begins, important teaching is already underway.
