In Montessori classrooms around the world, and in our Montessori school in South Philly, language lessons—such as Sandpaper Letters—are introduced based on each child’s interest, ability to concentrate, and readiness to understand, rather than on age alone. You might be surprised to learn that reading readiness has far more to do with a child’s inner development than with how old they are.v

Before introducing Sandpaper Letters, teachers carefully observe children for signs of readiness: sustained concentration, enjoyment of language, careful movement, and curiosity about sounds and words. Dr. Maria Montessori observed that children experience a natural “sensitive period” for language, during which they are especially eager to explore sounds and symbols. When lessons are offered at this moment, learning feels joyful and effortless rather than forced.
