3andB unlocking potential

About 3andB

Every lesson we sell was written by someone who had to teach it the next morning.

Not by curriculum writers working from a standards document, and not by a publisher with a template — by teachers who were tired of spending Sunday night building Monday.

  • 2,500+ ready-to-teach lessons
  • 100+ workbooks
  • Top 1% seller on TPT
  • Worldwide U.S. classrooms and beyond

That's the whole origin story. Lee spent sixteen years in classrooms teaching economics, CTE and special education, writing his own material the entire time because he wanted students walking out of the room knowing why any of it mattered. John spent seven years teaching science and was quietly doing the same thing across the building. Two people, two growing piles of material that actually worked in front of real kids. 3andB is what happened when we put the piles together and finally organized them.

The catalog is about 2,500 lessons and 100 workbooks now — biology, physical science, chemistry, physics, forensic science, the health science pathways, IT and computing, economics and personal finance, and a life-skills series for students about to age out of school without a plan. Teachers, districts and homeschool families buy it through TPT, where we're a top 1% seller, on Amazon, and straight from us, here and overseas.

The mission never moved. Build curriculum that gives teachers their time back and gives students a reason to care.

Everything we make has to survive an actual Tuesday. It has to be printable, sub-friendly, and free of logins, seat licenses and subscriptions that expire and take your materials with them. You bought it; it's yours.

And it has to answer the question every student eventually asks out loud — why does this matter? Whether it's mitosis or compound interest or a career they didn't know existed, the lesson has to connect to something outside the room. Students learn more when they understand why they're learning it. That isn't a philosophy so much as sixteen years of watching it happen.

That includes the students who usually get skipped: alternative programs, juvenile justice settings, dual-language classrooms, kids reading two grades behind who are still expected to pass a biology exam. They aren't a footnote in our catalog. A good part of it was built for them first.

Teachers hand our material to thirty kids on our word, and we take that seriously. Every lesson is researched, written, reviewed, edited, designed and checked before it reaches a classroom.

Alignment isn't a claim printed on a cover — we do it lesson by lesson, and when standards get revised we go back through and re-align the affected lessons rather than leaving old references in place. Nobody puts that on a banner, but it's the whole difference between material a teacher can use and material they quietly set aside. When the science moves, we update. Curriculum shouldn't stand still.

We're small on purpose, and every lesson that carries the 3andB name is read by all three of the people whose company it is.

Leecurriculum, and the code

Practiced law before he ever set foot in a classroom, and it shows in the writing more than anywhere else — get to the point, say plainly why it matters, don't waste the reader's afternoon. Sixteen years teaching after that, an M.Ed. in curriculum and instruction, recognition as a Master Teacher in Idaho, and curriculum development work at the state level. He's also been writing software for twenty-five years, which is the only reason a company this small builds its own tools instead of renting someone else's.

Johnscience, and the last read

One of those science teachers students still bring up years later, because he could always tell you what the content had to do with your actual life. He leads science and health science, and takes the final pass on everything in the catalog. Nothing leaves here without his read.

Katiedesign, publishing & marketing

She's the one who turns tens of thousands of pages of curriculum into workbooks that are organized, clean and ready to hand out. She's also a licensed cosmetologist, which brings real industry experience to our cosmetology and career-pathway material. If a workbook feels finished, that's her.

There are faster ways to make curriculum. We've looked at all of them and we don't think they're better. Writing the material was only half the job.

25,000+pages, set by hand

Lee and Katie laid out every single 3andB workbook by hand — more than 25,000 pages, one page at a time, no template dumps and no automated flow-and-hope.

5,000+puzzles, built by hand

John built every crossword and word search in the catalog himself, which is why the clues teach something instead of just hiding a word list. All the design is ours. All the photography is licensed from professional sources.

We do it this way deliberately. Nobody knows where a page should break better than the person who wrote the paragraph, and nobody writes a good clue about mitosis without understanding mitosis. We're small enough to care about every page, and we plan to stay that way.

We've always thought education was about more than clearing a test. Sometimes it starts with finally understanding photosynthesis. Sometimes it's learning how a credit card works. Sometimes it's finding a career you didn't know was an option. And sometimes it's realizing that a single habit, or a single thought, can change where a life goes.

Your greatest superpower is your ability to choose one thought over another. Choose the positive one.

That's how you live your best life. We don't include it because it sounds nice on a wall — we include it because it's a skill, and skills can be practiced and carried out the door long after graduation. The students who most need to hear it are usually the ones nobody's said it to.

We've been the teacher at nine at night with three preps to build and first period coming whether you're ready or not. We've been the teacher lying awake trying to make tomorrow mean something. That time comes out of somewhere, and it's almost always out of the teacher's own life.

So every hour we spend setting a page by hand is an hour a teacher doesn't spend building from nothing. That's the trade, and we'll take it every time. Give a teacher back an hour and it goes to their family, or to catching their breath, or to the kid who needs them most.

Because the best life for a student starts with a better one for the person standing at the front of the room. We build for both.

Lee and John are both available for professional development — curriculum design, course building, making content relevant to students, and integrating our material into your classroom, department or school.
