Language is an integral part of the entire Montessori preschool curriculum. Stories, songs, poems along with conversations with adults and peers help children increase their vocabulary and develop oral language skills. Written language is taught through a specific progression of lessons that engage the senses–children learn letters and sounds through seeing, hearing, and touching them–and through immersion in a linguistically rich classroom environment. Children first learn the phonetic sound of each letter. Using inviting, hands-on materials the children progress by classifying objects based on their sounds and then begin putting these sounds together to create words. Once they have learned to create their own words, reading follows quickly. As they progress with their reading, the focus turns to comprehension and grammar. With the development of language, children develop a greater ability to organize their thoughts and express themselves.
