The theoretical part defines the principles of Montessori education, the role of the teacher and the students, as well as the didactic resources and their impact on the teaching and learning process. The methodology applied was the qualitative approach. The research sample consisted of nine first-grade students and the English teacher. Through a face-to-face interview and an educational intervention based on the Montessori Methodology, we sought to answer the general question of the research: “how vocabulary acquisition is influenced by the use of sensory materials?” The results after the interpretation of the data collected, showed that the use of their senses is one of the most entertaining and engaging activities; therefore, it is concluded that the use of Montessori sensorial material promotes and generates a positive impact on their vocabulary acquisition development, besides the improvement of their communicative skills.
