Three developmental stages structure the elementary curriculum: before age nine emphasizes artistic foundations (music, drawing, writing derived from drawing, then reading); ages nine to twelve introduce grammar, natural history, and geometry as self-consciousness develops; ages twelve to fifteen add syntax, physics, chemistry, and history. Teaching methods must honor each stage's cognitive readiness, employ concrete demonstration over abstraction, cultivate truthful observation and will-activity alongside intellect, and carefully arrange the timetable to prevent sensory interference between simultaneous lessons.
