Every product is first proven with real children, then built. Experiment first, product second — that's the discipline.

A Child's Number Observation Diary V2

A diary of experiments for growing self-directed learning through play. Not a workbook — a guide that takes a child into the real world to discover the numbers already hiding there, and draw what they find. The second edition is finalized, and connected to the Number Kingdom game system.
