A child can only acquire the words he hears spoken around him. This is not teaching but absorption. The child is, by nature, hungry for words; he loves strange, long words like the names of dinosaurs and constellations. He takes in all these words without understanding their meaning, as his mind is still taking language in by a process of unconscious absorption.”

The Three-Period Lesson Is
The three-period lesson is a structured approach to learning: This is a sequential method designed to introduce and reinforce new vocabulary (also called nomenclature). It consists of three stages: naming, recognition, and recall.- The first period is about naming the object or concept without additional information. The child is encouraged to observe and absorb the information. The key words of this phase are “this is.” For example, the teacher says, “This is a square.”
- The second period reinforces recognition and association by asking the child to physically identify the object. The key words of this phase are “show me.” For example, the teacher says, “Show me the square,” and “Please pick up the square.”
- The third period assesses the child’s ability to recall and name the object independently. It is in this period that the child demonstrates their learning by naming the object. The key words of this phase are “what is this?” For example, while pointing to the square, the teacher says, “What is this?” The student responds, “A square.”
The three-period lesson is child-centered: The method is highly attuned to each child’s readiness and pace. It allows for individualized attention and ensures that each child can progress at their own speed, building confidence and mastery step by step.
The three-period lesson is interactive and engaging: The lesson requires active participation from the child. Through repetition and engagement, the child develops a deeper understanding and retention of the new vocabulary.
The three-period lesson is foundational in nature: The lesson is not just about learning specific words; it’s about building the foundational skills of observation, concentration, and memory that are essential for lifelong learning.
The Three-Period Lesson Is Not
The three-period lesson is not rigid or inflexible: While it follows a clear structure, the three-period lesson is flexible and adaptable to each child’s needs. It should not be forced or rushed; if a child is not ready to move from one period to the next, it’s perfectly fine to spend more time repeating and reinforcing the current stage.
The three-period lesson is not rote memorization: The goal of the three-period lesson is not mere memorization but genuine understanding. It’s about helping the child internalize a concept so they can recall and apply the concept independently, not just repeat it on cue.
The Montessori three-period lesson is a testament to the simplicity and effectiveness of the Montessori method. When teachers understand the lesson’s structure and purpose, they can use it to foster a love of learning and a deep, lasting understanding of new words. Remembering what the three-period lesson is—and what it is not—ensures that we use this tool to its fullest potential, always keeping the child’s best interests at the heart of our teaching.
