From TPT to My Own Website: How One STEM Lesson Grew into Something Bigger

I didn’t start this with a logo, a launch plan, or some perfectly organized business notebook.

I started with classroom lessons.

On July 14, 2026, I opened the door to something I thought would be pretty simple. I had already made a bunch of STEM activities for my own middle school students, and I figured I might as well put them somewhere other teachers could use them too. If it helped me make a little extra income, even better.

That was honestly the whole plan.

I wasn’t trying to become a “teacherpreneur.” I wasn’t thinking about building a website. I definitely wasn’t thinking about marketplaces, bundles, product descriptions, or email lists. I was just a middle school STEM teacher with a folder full of lessons I had actually used, revised, and cleaned up after real students had asked real questions like, “Wait, are we supposed to build it or draw it?” and “Can we use tape for literally everything?”

And somehow, one uploaded lesson turned into a full teacher resource business faster than I expected.

It started with lessons that were already working in my classroom.

I started with resources I had already tested with students

The first thing that made this feel doable was that I wasn’t starting from scratch.

I already had lessons sitting in my files because I needed them for my own classroom. If you teach STEM, you know how that goes. Sometimes you need a quick bell ringer because the first five minutes of class can make or break the whole period. Sometimes you need an engineering challenge that keeps students busy and thinking. Sometimes you need an exit ticket that tells you if they actually understood the concept or if they just had a really good time using scissors.

So my first resources came from real classroom needs.

I had STEM labs. I had challenges. I had problem-solving activities. I had materials connected to AI literacy, cybersecurity, STEM careers, engineering disasters, back-to-school routines, and all those little pieces that help a class run smoothly.

At first, I looked at these files as “lessons I made.” That was it.

Then I started seeing them differently.

A bell ringer wasn’t just a bell ringer. It was part of a routine.

An exit ticket wasn’t just a question at the end of class. It was a quick check for understanding.

A STEM career activity wasn’t just filler for a Friday. It was a chance for students to see that engineering, coding, cybersecurity, robotics, construction, aviation, and environmental science are connected to real jobs.

That shift mattered.

I wasn’t just uploading worksheets. I was organizing the same kinds of classroom tools I wished I had more of when I was planning at night, trying to make tomorrow’s lesson make sense.

The store grew way faster than I expected

Once I started creating, I didn’t really want to stop.

That surprised me a little.

I thought I’d upload a few things, check on them once in a while, and maybe make a sale here or there. Instead, I found myself constantly thinking of new resource ideas during the school day.

A student question would turn into a bell ringer idea.

A rough class period would turn into a better set of instructions.

A unit that needed more student choice would turn into a choice board.

A quick warm-up would turn into a set of 20.

That’s when my Teachers Pay Teachers journey started to feel less like a side experiment and more like something I actually enjoyed building.

Within about a month, my TPT store had passed 200 products and dozens of bundles. I know that sounds like a lot, and it was. But it didn’t happen because I sat down and magically created 200 brand-new ideas out of nowhere.

It happened because many of the ideas were already connected.

For example, if I made a set of STEM bell ringers, I could often create matching exit tickets. If I had enough of those, I could turn them into a weekly routine. If I had several weeks, I could make a larger bundle. If I had enough related activities around AI literacy, cybersecurity, or engineering careers, I could package them in a way that made planning easier for another teacher.

That was one of the first big lessons I learned.

One classroom idea can become more than one useful resource.

Not in a spammy way. Not by copying and pasting the same thing over and over. I mean in a practical teacher way.

If a topic is useful enough to teach, there are usually multiple ways students can interact with it:

• A quick question to start class

• A short activity to explore the idea

• A challenge or lab to apply it

• An exit ticket to check understanding

• A choice board to give students options

• A bundle to save another teacher time

  
  

That was a huge “ohhh, I get it now” moment for me.

Every resource idea came from something students could actually do.

The Mega Pack changed how I saw the whole thing

The biggest example of that “one idea can grow” lesson was my 120-day STEM Mega Pack.

It started with smaller resources. Bell ringers. Exit tickets. Choice boards. Things I had been making because I knew teachers needed routines that didn’t take forever to prep.

After a while, I realized those resources could work together as a bigger system. A teacher could use a bell ringer to start class, an exit ticket to wrap it up, and choice boards to give students independent or extension work. Instead of selling only the separate pieces, I bundled them into one larger pack.

That bundle became my 120-day STEM Mega Pack, priced at $47.90.

And then it sold.

That sale hit differently.

It wasn’t just the amount, although at the time it was my biggest sale and I was absolutely excited about that. It was what the sale represented.

Somewhere, another teacher looked at something I had made and thought, “Yes, this could help me.”

That was the part that stuck with me.

Teachers are careful with their money. We all know that. A lot of us buy things for our classrooms out of our own pockets. So when another educator buys a resource, it means they see value in it. They are trusting that it will save them time, help their students, or make one part of their day a little easier.

That made me take the work more seriously.

Not in a stiff, businessy way. More like, “Okay, if teachers are using this, I need to make sure it’s clear, useful, and ready for an actual classroom.”

Because there’s a big difference between a cute activity and a resource that survives seventh period.

Middle school STEM resources have to be flexible. Students need clear directions. Teachers need materials that don’t require 19 special supplies. Activities need to work with real class periods, real student energy, and real interruptions like fire drills, missing Chromebooks, and somebody asking to go to the nurse three minutes after class starts.

That became my filter.

Could I use this myself?

Would another teacher understand it quickly?

Would it still work if a class was loud, mixed-level, or running ten minutes behind?

If the answer was no, I worked on it more.

I started asking why I was only selling in one place

For a while, I only thought about TPT.

That made sense. It’s one of the best-known places for teacher-created resources, and it was the first marketplace I understood enough to start using. But after I had built up a growing catalog, a question kept popping into my head.

“Why am I only selling on TPT?”

That question changed my workflow again.

I started learning about other platforms where teachers look for resources, including TES, Classful, and Teach Simple. I didn’t know everything about them at first, and I still don’t claim to know everything now. But I did know this: if I had already created a resource, uploaded the preview, written the description, and organized the files, it made sense to let that resource reach more teachers.

So I began cross-posting.

At first, I treated it like an extra task. Something I would do when I had time. But “when I have time” is a dangerous phrase during the school year, because we all know that time usually disappears into grading, planning, emails, and trying to remember where we put the good scissors.

So I recently made cross-posting part of my normal workflow.

When I create a resource now, I think about where else it can go. I adjust the title and description for each marketplace instead of copying everything exactly the same way. Different platforms have different layouts, search styles, and audiences, so the wording sometimes needs to shift.

The resource stays the same at its core, but the way I describe it may change.

That has become part of building a stronger teacher resource business. Not because I’m trying to sound fancy, but because I want each resource to have a better chance of being found by the teacher who needs it.

Cross-posting made me think more carefully about how each resource is described.

Buying my own website made everything feel real

The next step felt bigger than uploading another product.

I bought innovativemiddleschoolstem.com.

Even typing that still feels a little wild.

I had been building resources under Innovative Middle School STEM, but buying the domain made it feel like this work needed a home base. Marketplaces are helpful, and I’m grateful for them, but they’re still rented spaces in a way. My own website gives me a place to organize everything the way I want.

So I started building the site on Wix.

Nothing about that process has been perfect. I’ve moved sections around. I’ve changed pages. I’ve stared at the screen wondering why something looked good in my head and weird on the page. But little by little, it has started to become the home base I pictured.

The plan is for the site to include:

• STEM resources

• Free resources

• Blog posts

• Links to marketplace shops

• Updates about new products

• Eventually, an email list

  
  

The email list piece is still something I’m working toward. I like the idea of having a way to tell teachers, homeschoolers, and parents when new resources are available without depending only on a marketplace algorithm or a random search result.

More than anything, I want the website to feel useful.

If someone lands on Innovative Middle School STEM, I want them to be able to find practical STEM teacher resources without digging through a mess. I want the free resources to be easy to grab. I want the blog to sound like a real teacher wrote it, because a real teacher did.

That matters to me.

There are already plenty of polished, generic education websites out there. I’m not trying to pretend my classroom is perfect or that every lesson runs like a highlight reel. I want this to be a place that feels connected to actual teaching.

The kind where you can say, “Here’s what worked, here’s what I changed, and here’s what I’d do differently next time.”

I’m learning that small experiments add up

One funny thing about this whole journey is that none of the individual steps felt huge when I took them.

Uploading one lesson didn’t feel huge.

Making one bundle didn’t feel huge.

Cross-posting one product didn’t feel huge.

Buying a domain felt bigger, I’ll admit that one made me pause for a second.

But looking back, all those small experiments started stacking on top of each other.

That’s probably the teacher part of my brain too. We tell students all the time that trial and error is part of STEM. Test the bridge. Change the design. Try a different material. Figure out why the code didn’t work. Redesign the solution.

Apparently, I’ve been doing the same thing with my resources.

I tried one marketplace, then another.

I tried individual products, then bundles.

I tried small resources, then larger packs.

I tried keeping everything on platforms, then started building my own website.

None of it came from a perfect plan. It came from noticing what was working and being willing to try the next thing.

That’s a pretty STEM way to build something, now that I think about it.

The whole journey still connects back to the classroom.

What I hope Innovative Middle School STEM becomes

At the heart of all this, I still see myself as a classroom teacher first.

That’s where the ideas come from. That’s where I learn what students need. That’s where I notice which directions are confusing, which activities are too long, and which topics make students suddenly sit up and start asking better questions.

Building Innovative Middle School STEM has made me realize that the work we create for our own classrooms can sometimes help far beyond our own schools.

A bell ringer I made for my students might help a homeschool parent start a STEM lesson with less stress.

A cybersecurity activity might help a teacher introduce a topic they haven’t taught before.

An engineering disaster lesson might give students a real-world example that sparks discussion.

A back-to-school STEM challenge might help a class build teamwork during the first week.

That’s the part that keeps me going.

Yes, the extra income matters. Teachers work hard, and finding a way to earn from work you’ve already poured time into is meaningful. But the more I build, the more I see that this is also about sharing classroom-tested ideas with people who are trying to do good work with students.

If you want to see what I’m building, you can visit Innovative Middle School STEM and follow along as the site grows.

I started on July 14 without a master plan. I was simply experimenting. I had lessons I had made for my own students, and I wondered if they might help someone else too.

Now I’m realizing those classroom-created resources can reach teachers, homeschoolers, parents, and students far beyond my own school.

I'm still figuring it out as I go, but honestly, that's probably my favorite part.
