There is one rule we will not negotiate on — AI never does the reasoning your child should be doing. Here is exactly what that means in product terms, and the five scaffolding patterns we use instead of letting the model write the answer.

Why kids who learn structural thinking outpace kids who learn answers
The cost of getting a confident-sounding wrong answer dropped to zero. The cost of building the judgment to recognize one didn't. This is what to teach an 8-to-12-year-old now — and why it isn't "critical thinking" as you remember it.
