Stepping into your classroom for the very first time is one of those moments you never forget. Before my first year began, I remember bouncing between pure excitement and complete panic. I had my dream job teaching 11th grade U.S. History. Yet, I still felt like I was standing at the edge of something enormous. I knew my content. I had survived (and even thrived!) during student teaching. There’s just something different about being the person at the front of your classroom with your roster, your routines, and your expectations.
That first year was challenging in ways I didn’t expect. It also shaped me into the teacher I later became. If you’re a first year teacher, especially at the high school level, you deserve support, honesty, and real talk from someone who’s been exactly where you are. Let’s walk through ten things I wish someone had told me before I ever hung the first poster on my wall.
Being a first year teacher means you’re juggling a hundred new things at once. We're talking grading policies, classroom management, content prep, school culture, and even remembering where the good stapler lives. While all of that can feel overwhelming, it’s also the start of something exciting. You’re about to build connections, impact teenagers’ lives, and create a classroom that reflects who you are as an educator.
This section of your career is supposed to feel messy and unfamiliar. That doesn’t mean you're unprepared. It means you’re becoming the teacher you’re meant to be. So take a breath. Give yourself grace. And know that the tips below are designed to help you feel supported, grounded, and ready for what comes next.
When you walk into the classroom for the first time, it’s easy to want to change the world by third period. The truth every first year teacher needs to hear is that impact takes time. High schoolers don’t automatically trust you because you have a shiny new lanyard. Relationships are built slowly, one interaction at a time.
You’ll have days where you walk out feeling like you nailed it and days where you wonder if any teen in the building heard a single word you said. That’s normal. What matters is that you stay grounded in the small wins. The quiet student who suddenly participates, the class that laughs at your joke, the kid who asks for help because they trust you. Those moments are the foundation of everything else.
Teaching at any level is hard, but in high school, the emotional and psychological strain can sneak up on you fast. Teenagers negotiate everything from deadlines, rules, expectations, you name it. If you aren’t careful, you’ll spend half the day debating instead of teaching. That’s why clear, simple, consistent rules matter. Think about what worked (or didn’t!) during student teaching. Then ask a few veteran teachers in your building what they do. No friendly mentors on your campus yet? Try online communities like Teaching History with History Gal for insight and support.
Start with a short list of rules. Seriously, less is better. Enforce them with calm consistency. Don’t negotiate every request. Don’t soften boundaries because you’re worried about being liked. Teens may push back in the moment, but long-term, they respect teachers who are steady, fair, and genuine. You won’t win every kid over right away. Some of your students will challenge you every single class period. When you stay consistent and show them that your decisions can be trusted, you’ll make progress that matters.
If you're a first year teacher teaching a subject outside your comfort zone, break the content into manageable chunks and learn with intention. Lean on YouTube channels, podcasts, teacher blogs, or colleagues to help fill the gaps. Build ten minutes of buffer time into your lessons. Trust me, you’ll use it. Whatever you do, create a folder of anytime activities for when the copier breaks, technology fails, or a lesson tanks. You’ll thank yourself later.
Being prepared doesn’t look like perfection. It looks like resilience, curiosity, and the willingness to adjust when things go sideways.
When an activity stalls, don’t try to convince your students to love it. Move on. Switching gears gracefully saves time, protects your confidence, and keeps the energy in the room from sinking. On the flip side, when something is working, really working, let it grow. Extend the conversation. Give them extra time to collaborate. Ride the momentum. Flexibility isn’t losing control. It’s the ability to read the room and respond with confidence.
Scrolling through Instagram, Pinterest, or teacher TikTok can feel like torture during your first year. Everyone seems to have the perfect classroom, flawless anchor charts, gorgeous bulletin boards, and systems that run like a dream. Those posts are carefully curated highlight reels. They do not always show the everyday chaos that every high school teacher experiences.
It's so easy as a first year teacher to constantly compare yourself and lose sight of what truly matters, which is the connection, growth, and authenticity you create with your students. Your students don’t care if your classroom is Pinterest-perfect. They care that you show up with humor, patience, fairness, and honesty. High schoolers are human lie detectors. They value real teachers, not polished performances.
Make it a goal to build trust early. Greet your students at the door. Celebrate their wins. Notice who needs encouragement. When your students know you’re on their side, those tough management moments get easier, participation increases, and the class culture becomes something you’re proud of. For all teachers, relationships are foundational.
Consistency is a gift to both you and your students. High schoolers crave structure, even if they pretend otherwise. Routines help your classroom run without constant reminders and reduce unnecessary stress.
Create predictable systems:
• How your students enter and start class
• How to submit work
• What to do when they’re finished
• How you handle phones
• How you manage group work
• What transitions look like
As a first year teacher, sticking to routines makes your days smoother and helps your students feel more secure. Once your procedures are established, you’ll find you have far more energy for the parts of teaching you love.
As a first year teacher, your main job is to build strong instruction and a strong classroom culture. Don’t be afraid to say no. Protecting your prep periods, your evenings, and your mental bandwidth isn’t selfish. It’s strategic and essential to your well-being. There will be many years to join extra activities at school. This year, invest in yourself.
Your first year is not meant to be done alone. You need people. People who will answer your “Is this normal?” questions, who will talk you through tough days, who will share their lesson resources, and who will remind you that you’re doing better than you think.
Find those people. They might be in your hallway, in another department, or online in communities built for teachers. Mentorship doesn’t have to be formal. Sometimes the teacher down the hall who lets you vent between classes becomes your lifeline. As a first year teacher, it's so important to create a community for yourself to stay energized and grounded. We always say it takes a village to support our students. The same can be said for being an effective teacher.
High school teaching moves fast. It’s easy to replay awkward moments or tough interactions on a loop after the bell rings. You don’t have to walk out every day feeling victorious. You just need to stay open to learning. A simple reflection routine, like jotting three things that worked and one thing to adjust, keeps your growth grounded and your confidence intact. Teaching is a profession built on constant evolution. Reflection is what helps you evolve with purpose instead of pressure. This is the habit that will shape you not just for your first year, but for every year that comes after.

5 Takeaways from This Chapter:
Another must-have is a clear schedule layout. If your school runs on A/B days or rotating classes, try to make the schedule as visual and straightforward as possible. I’ve found that including a quick chart or even color-coding the classes can save a substitute a lot of confusion. The easier you make it for them to follow your day, the smoother everything will go in your absence.
I also always leave emergency lesson plans. They are simple, flexible activities that don’t depend on what we’re currently studying. These lessons usually cover topics that I know we have already covered. This way, if I’m unexpectedly out, I know the substitute can grab a plan that works with any unit. I also leave space for them to jot down how things went or if certain activities were particularly successful. It’s such a helpful way to stay in the loop when you return.
Each activity in the No Prep Sub Plans is self-contained. This means substitutes can easily pick up and teach without extra prep. Let's take a peek at some of the activities.
"Whose Phone Is This?" gets your students thinking creatively about historical figures through a modern lens. Students will choose a historical figure that they have learned about and answer questions based on what that figure might have on their cell phone if they lived today. It's a fun and engaging way to get students thinking about these figures as "real people" and not just a character in their textbook.
The "Historical Front Page" is a 45–60 minute activity that has your students creating a front page for a historical event you have studied in class. Using both pictures and words, students must create the front page of a newspaper that is covering the historical event. Students must focus on accuracy, creativity, and connections to their notes.
The Infographic Activity allows your students to demonstrate understanding visually. After being introduced to how infographics share information using images, your students will create their own infographic. This activity is perfect for classes with diverse learners.
There are even two puzzle options that are perfect for shorter class periods. Using the Crossword Puzzle and Word Find activities, students will reinforce vocabulary and key people from recent lessons. Students love creating the puzzles and then trading with a classmate to solve a puzzle.
Your students who love social media will get a kick out of "History Book" and "Chatter". In these activities, they create mock profiles or posts for famous figures. These 30–45 minute tasks combine history and pop culture, making even the most reluctant learners excited to participate.And. . . there are more activities included in this resource! Whether your substitute needs to fill one class period or an entire day, there’s enough variety to choose from while still keeping the work meaningful. What makes these sub plans stand out is the creative mix of activities.
With all these options at your fingertips, you can easily build a sub folder that’s flexible, engaging, and completely no prep. Every activity is designed to stand alone, which means your sub doesn’t have to stress about keeping up with your pacing guide. You also don’t have to worry about reteaching everything when you return.
Another helpful tip is to store your sub folder somewhere obvious. I keep mine in a clearly labeled binder right by my computer so it’s easy to find. I even let a trusted colleague know where it’s kept, just in case I’m ever out unexpectedly. If your school uses Google Drive, it’s worth uploading a digital backup there too. That way, everything, from rosters to sub plans, is just a click away.
Don’t forget the personal touch. I always include a thank-you note and, when possible, a small token of appreciation for my sub. Whether it’s a coffee gift card or a quick promise to cover their class in return, showing gratitude goes a long way. Substitutes often step into chaos, and a little kindness can make their day.
