Child development:
  • Sensorimotor (birth–2): Sensory exploration, object permanence.
  • Preoperational (2–7): Symbolic play, egocentric thinking, magical elements, rapid language growth—but limited logic (e.g., no conservation).
  • Concrete Operational (7–11/12): Logical thinking about concrete (tangible) things; better perspective-taking, classification, cause-effect; less egocentric.
  • Formal Operational (11/12+): Abstract/hypothetical reasoning emerges (politics, ethics, 'what if' scenarios), though many don't fully reach it until later teens/adulthood.

Levels are skill-based (kyū progression), not age-locked. Parents/instructors determine grouping based on the child's cognitive readiness, maturity, physical ability, and interest. Use Piaget-inspired guidelines (e.g., concrete examples for younger; abstract reflections for older) to adapt topics like human nature/power in World Study or character modules.

Central to our dojo is the unwavering protection of children and respect for biological reality. There are two sexes—male (he) and female (she). We stand against any form of manipulation or early indoctrination. Our commitment is simple: protect kids, honor boundaries, and let children be children—no hate, just clear safeguarding.
