CRUSH SCHOOL

I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.

Why Student Engagement Is One of the Best Classroom Management Strategies.

Illustration of an engaged high school classroom with students discussing, writing, raising hands, and collaborating while the teacher stands calmly in the center under the title “Best Classroom Management? Student Engagement.”

The best classroom management often starts before behavior becomes a problem—with student engagement, active learning, curiosity, and participation.

I don’t know about you, but whenever I’m observed by admin I always worry about my classroom management.

It’s not that I’m bad at it. I just worry about being judged or feeling inadequate.

Kids are kids and will behave the way kids behave, but as teachers we all want fewer disruptions, smoother transitions, stronger routines, and students who actually stay with us mentally instead of drifting into the land of side conversations or ceiling-tile analysis.

But what took me 20+ years of teaching to fully understand is this: The most effective classroom management has less to do with seating charts, rules, or consequences than we think. Those things have their place, but they don’t replace the one thing that changes the entire energy of the classroom—student engagement.

Because when students are curious, moving, talking, thinking, predicting, retrieving, and creating, they have less time to derail the learning train.

But while engagement does not magically solve every behavior issue, we all know that bored, disengaged students are harder to manage than students who are busy thinking, talking, creating, and actively learning.

When students sit too long, listen too long, copy too long, or wait too long, attention drifts. And once attention drifts, unwanted behaviors usually follow.

That’s why strong classroom engagement strategies matter so much. This is especially true at the beginning of the school year.

The first days of school are not just about rules and procedures. They are also about showing students what learning will feel like in your classroom.

Will class be something they sit through or something they participate in?

That’s where simple active learning strategies can make a huge difference.

A strong bell ringer can spark curiosity before the lesson even starts. A quick prediction can pull students into the content. A movement activity can reset attention in the middle of class. A review game can turn retrieval practice into something students actually want to do.

This is the idea behind Spark. Wire. Fire.: 100 Ready-to-Use Classroom Activities That Inspire Curiosity, Strengthen Memory, and Apply Learning.

The book is built around a simple learning sequence:

Spark curiosity and attention.
Wire learning into memory.
Fire learning into application.

Instead of starting the year with only policies, packets, and procedures, teachers can use engaging first day activities and bell ringers that help students practice the kind of thinking we want all year.

For example, Prediction Mystery gets students making guesses and defending their reasoning before the reveal. Mystery Object uses curiosity to pull students into the lesson any time during the school year. Wrong Answer Warm-Up turns misconceptions into discussion. Word Unscramble gives students a low-risk puzzle that primes the brain for learning.

For review and memory, strategies like Last Team Standing, 3-2-1 Recall, and Draw the Definition help students retrieve information instead of passively rereading it.

For discussion and application, activities like Real-Life Detective, Future Headline, Four Corners Chaos, and Chain Reaction get students talking, defending ideas, connecting concepts, and applying what they know.

That’s the kind of classroom management I want more of.

Not quieter students. Quiet does not always equal learning.

I want more engaged students, even if it gets loud sometimes. I want more thinking, curiosity, and active participation. I want more learning that sticks.

As we all prepare for a new school year, it’s tempting to focus only on rules, routines, and procedures.

Those matter. A lot.

But we should also plan for engagement.

Because the best classroom management often begins before behavior becomes a problem.

It begins with a spark.

The Biggest Mistake I Made This Year

Teacher reflection graphic about skipping the spark, showing classroom lesson hooks, bell ringers, prediction activities, and attention-getters that help students focus and prepare for learning.

Sometimes the biggest teaching mistake is skipping the spark. A strong bell ringer or lesson hook helps students activate prior knowledge, focus attention, and enter the learning before the lesson begins.

The biggest mistake I made this year wasn’t a failed lesson, a bad lab setup, or one of those assignments that looked good in my head and then completely bombed in the classroom.

It was simpler than that.

Too often, I skipped the spark.

The truth is that I know better. I knew better…

I really did, but some days I was tired. Some days I felt lazy. Some days too much was going on in my brain or at school and I couldn’t summon enough energy to start class with something clever, active, or interesting.

So I did what many teachers do when we’re exhausted.

I’d start with something like:

“Homies, take out your Chromies.” - kind of clever but not the kind I’m going for. I’d follow with, “Here’s what we’re doing today.”

Class started, but learning didn’t always start the way I’d like.

My classes are very project-based. If you mix it up and provide a variety instead of “doing another poster,” students really enjoy and learn from these challenges. Most of the time, the projects I design—infographics explaining and giving examples of concepts visually, animations that show how processes work, educational videos that teach others various scientific ideas, engineering challenges that force students to brainstorm, collaborate, ideate, and apply what they’re learning, and others—last between two to five days. And, much of the time, I let students get right into them as soon as they get to class.

Nothing wrong with such agency—they wanted to “get to it” to get it done, but the part I kept noticing (and not correcting) was that on these projects days my students would really benefit from a quick bell ringer or hook—something connecting to the ideas they were learning during the course of the project.

Skipping the opening spark left some students “cold.” Their brains were still in the hallway, at lunch, on their phones, in yesterday’s drama, or already thinking about what they were doing after school.

I was ready to help and teach them, but they were not always ready to learn.

There was a gap I wasn’t noticing or doing anything about.

A good bell ringer, lesson hook, attention getter, or movement-based opener is not just a cute activity. It is not something we do because Pinterest said so.

It is the spark.

And the spark matters because the brain needs a reason to pay attention.

Before students can learn something new, they need to activate what they already know. They need a point of curiosity—a question, puzzle, prediction, image, mistake, or challenge that pulls their attention toward the learning.

That is what good lesson hooks do. They prime the brain for learning, activate prior knowledge, or create curiosity. Some of them accomplish all three.

But more importantly, they make students mentally available before we ask them to work with and process new information.

And when I skipped that step, I often paid for it later.

The lesson or project became harder. The explanations took longer. Students needed more redirection and reminders. The room felt flatter.

Not every time, of course, but often enough to realize when I reflected later.

The days I started with a strong spark were different.

A weird object on the front table. A wrong answer on the board. A prediction prompt before a demonstration I was about to do. A quick team challenge. A movement-based opinion question. A visual puzzle.

Suddenly, students were looking, talking, arguing, guessing, laughing, remembering, and asking questions.

It’s like magic, but that’s what attention and engagement can look like.

And attention is the gateway to learning.

This is one of the ideas behind my new book, Spark. Wire. Fire.: 100 Ready-to-Use Classroom Activities That Inspire Curiosity, Strengthen Memory, and Apply Learning.

The structure is simple:

Spark students’ interest.
Wire the learning into memory.
Fire it through application.

The Spark section includes 20 engaging priming, attention, movement, bell ringer, lesson hook, and attention-getter activities designed to help students enter the learning before the lesson really begins.

Here’s one I call Mystery Reveal:

Mystery Reveal: A Spark Activity from Oskar Cymerman’s new book: Spark. Wire. Fire.: 100 Ready-to-Use Classroom Activities That Inspire Curiosity, Strengthen Memory, and Apply Learning.

Each activity in the book is intentional. I didn’t know it when I started writing it, but the book has become a vehicle for me to become a better teacher.

Reflecting on how I can do better, researching why certain strategies work while others don’t, and creating engaging and meaningful classroom activities brought about a renewed understanding of what learning is and what teaching can look like—impactful, rewarding, and, yes, fun.

The Spark. Wire. Fire. book is a way of telling myself: “Here are the tools. Use them. No more excuses.”

I’m planning on it because I’m not trying to repeat my mistakes.

For one, I will not assume students are ready just because class has started.

I need to help them get ready by sparking their attention and interest.

No pressure.

Beacause if you’ve ever skipped the spark because you were tired, overwhelmed, or just trying to survive the day, I get it.

I’ve done it too. I don’t feel bad or dwell on it. It is what it is, because teaching ain’t no cakewalk.

I’m just trying to do it less and do a little better each time I get out there.


My new book Spark. Wire. Fire.: 100 Ready-to-Use Classroom Activities That Inspire Curiosity, Strengthen Memory, and Apply Learning is about giving teachers ideas and practical examples you can use to make your lessons more engaging, memorable, and impactful.

What Worked This Year? A 15-Minute Teacher Reflection Routine

Before summer break begins, take 15 minutes to reflect. Keep what worked, change what needs improvement, and drop what no longer serves you or your students.

I don’t know about you, but by the last day of school, I am ready to close the door and not think about teaching again until mid-July or August if you can.

And honestly, we've earned that.

But before summer completely takes over, I spend 15 minutes capturing what the year taught me.

Because the best ideas are easy to forget. I know because I’ve forgotten things I wish now I knew.

To avoid this, I periodically make quick notes in my ideas notebook.

At the end of the school year, I make three simple lists and revisit them later in August. I hope they help you. Here they are.

Keep

What lessons, routines, activities, or strategies worked so well that you'd use them again tomorrow?

Change

What kind of worked but needs improvement? Maybe better timing, clearer directions, or less complexity can make it work much better?

Drop

What caused more headaches than learning? Even if you spend a good deal of planning time on it, not everything deserves to survive another school year.

Think About Students

  1. Which activities generated the most discussion?

  2. When were students genuinely engaged?

  3. What moments brought the most joy?

Those moments make all the difference.

Keep It Simple

  1. No massive spreadsheets or 40-page reflection binders.

  2. One page of notes makes it likely you’ll actually revisit it.

Future you will thank you.

Last Thing

Teaching gets better one year at a time.

It’s not because we reinvent everything, but because we remember what mattered, what confused, and what simply sucked.


You’ve captured the lessons—now close the notebook and enjoy your well-earned break.

QUICK NOTE: My new book Spark. Wire. Fire.: 100 Ready-to-Use Classroom Activities That Inspire Curiosity, Strengthen Memory, and Apply Learning can help you turn those reflections into a stronger, more engaging school year.

The paperback is coming July 15th.
