Three free async classes this month, no strings attached. An AI robot explaining himself, the real science Ray Bradbury hid inside a short story, and what it would actually take to grow food on Mars.

If your kids know Sir Cumference and the Dragon of Pi, these are the four we actually own, and one of them beat Dragon of Pi as our actual favorite, gummy bears included.

Shelf Life: a family reunion gone sideways over table arrangements, and the popsicle-stick building project my kids couldn't stop tinkering with once they saw why it mattered. Area and perimeter, hands-on, no worksheet required.

Welcome to Shelf Life—a series of short, practical reviews of the books that actually worked in my classrooms, homeschool, and co-ops. Mostly STEM, with the occasional history detour (because even a science teacher needs a good story). This first post: the money and coin books that helped my dyscalculic child see math.

Our newest free printable, The Founder's Lost Fortune, is built for exactly the kind of kid who groans at a worksheet but will happily do thirty math problems if a treasure hunt is on the other side of them.

6 pre-algebra worksheets, each built around a different interest, video games, sports, racing, music, farming, and shopping. Percentages, ratios, and rates show up in almost all of them, but each theme also brings its own twist, farming adds real geometry, music adds fractions, video games even sneak in exponential thinking. No email required, just print and go.

I read a lot of middle-grade novels looking for the right science hook, and most of them just don't have one. They're good stories, but the science is either missing entirely or stapled on at the end. City of Ember is different. It doesn't just contain science. It's structurally about the loss of it.

If your student spends more time in the kitchen than at a desk, good news: they've been practicing pre-algebra the whole time without knowing it.

Solving for x was never actually the hard part. A student can memorize "isolate the variable" in ten minutes. What takes years to build is the skill of looking at a real situation — a grocery receipt, a recipe, a stat sheet — and recognizing which math it's even asking for. That translation step is the skill that gets skipped when kids only ever practice equations someone already set up for them.

A locked strongbox. A note that raises more questions than it answers. A ledger full of numbers that don't add up, yet. This is how Fox Hollow Files begins, and it's the same case your student spends the whole year solving.

Picture this: it's late afternoon, you need to get dinner going, and you desperately need a genuinely focused hour without refereeing sibling fights. Enter the "Interest Box"—the ultimate tool to keep kids from 1st to 7th grade independently engaged using topics they already love.
