The same principles, everywhere.

Decomposition + the function machine

Programming is the five questions running at machine speed: What pattern exists (this loop is that loop)? What assumptions changed (the bug is always a broken assumption)? Can this generalize (that's what a function is)? Teach kids to break problems into pieces small enough to be obvious — the identical skill as splitting 13×7 along the tens. Debugging is the error autopsy with a compiler for a lab partner.

Tonight: Scratch for youngers, Python for olders — and narrate your own debugging out loud: 'my assumption broke; let's find where.'

Pattern libraries + productive struggle

Chess strength is mostly a library of recognized patterns — forks, pins, back-rank weaknesses — built through thousands of small exposures, exactly like multiplication facts. Puzzles are retrieval practice; losses are error autopsies; rating graphs are the growth dashboard. It's the entire method on 64 squares.

Tonight: Leave a board out mid-puzzle with a sticky note: 'White wins in 2.' Do one puzzle a day next to your child — visibly failing sometimes.

Compression + transfer

Writing is thinking made inspectable. The 'convince me' page is proto-essay; dinner arguments are proto-thesis-and-evidence; the curiosity journal is a writer's notebook already. Revision is where the learning lives — first drafts are productive struggle, and treating them as drafts (not verdicts) is growth mindset applied to sentences.

Tonight: Family rule: everyone drafts fast and revises once. Read a paragraph aloud and ask the invariant question — 'what is this paragraph really about?'

Chunking + spaced micro-practice

Ten minutes of daily practice beats seventy on Sunday — spacing again. Difficult passages are bottlenecks: isolate the two hard measures instead of replaying the whole piece (targeting again). Scales become chunks, chunks become phrases, phrases become expression — compression, audible in real time.

Tonight: Shrink practice to a daily two-minute anchor on the hardest two measures only. Keep the instrument out of its case, on a stand, in the living room.

Deliberate practice + effort culture

Sports may be where kids learn the method's deepest lesson viscerally: you get better at what you deliberately practice, and only that. Scrimmage is fun; targeted drills move the needle — bottleneck thinking with a ball. Film review is the error autopsy. The effort-praise protocol matters doubly here, where talent-talk is loudest.

Tonight: Ask 'what's the one skill that would most change your game?' — then design a five-minute daily drill for exactly that.

First principles + invariants

Engineering is applied 'why?': every bridge, toaster, and paper airplane is a frozen argument about forces and constraints. Building things teaches that failure is data (the tower fell — what assumption broke?), that constraints breed creativity, and that the real world grades honestly.

Tonight: The spaghetti-and-marshmallow tower, tonight, whole family, twenty minutes. Autopsy the collapse together like it's treasure.

Better questions + measurable goals

The advocacy layer is secretly a leadership curriculum: understand incentives, build partnerships before you need them, convert vague concerns into measurable asks, document and follow up. Children who watch a parent run a respectful, evidence-based school meeting are watching a masterclass in influence without authority.

Tonight: Give a child real leadership of something small — the vacation map, the grocery budget — with a real goal and a real debrief.

Bottlenecks + dashboards

A lemonade stand is a systems curriculum: unit economics (ratio), pricing (percentages), inventory (estimation), location (environment design!). Business thinking is bottleneck thinking — of everything that could improve, what's the constraint? — plus the honesty of a dashboard that tracks reality instead of hope.

Tonight: Any kid enterprise: have them guess the bottleneck ('more customers? faster service?'), change one thing, measure. That loop is the whole MBA.

Socratic tools + metacognition

Children will spend their lives working alongside AI. The method's contribution: use it as a thinking partner, never an answer machine. A child who prompts 'quiz me and don't tell me the answer until I've tried' is doing retrieval practice with infinite patience on tap — a child who prompts 'do my homework' is outsourcing the struggle that was the entire point.

Tonight: Set the family norm early: AI asks us questions. See the full AI section for the tutor prompt that enforces it.

Ratios + transfer made delicious

The kitchen is the cheapest math lab in the world: scaling a recipe for six is proportional reasoning with real stakes, doubling a cake tests whether ratios generalize, and 'why did the bread rise?' starts a five-whys chain that ends in biochemistry. Mistakes get eaten — the friendliest possible error autopsy.

Tonight: Hand over a real recipe that must be scaled — 'this feeds 4, we're 6' — and let the child own the arithmetic and the outcome.
