The first essential for the child’s development is concentration. The child who concentrates is immensely happy.
— Maria Montessori

Casa (Pre-School)


Our Casa (pre-school) program contains five areas of study: Practical Life, Sensorial, Language, Mathematics, and Culture. This classroom houses students from 3.8 to 6 years of age. These areas of study coupled with the multi age mix of students is a very dynamic learning environment, which provides the students with the opportunity to evolve into disciplined, enthusiastic, self directed learners.

As dictated by Maria Montessori, the child is born a learner. The prepared environment at CGMA allows for the natural progression of learning to take place spontaneously and effortlessly.

A Montessori philosophy fosters further refinement of the child's own innate potentiality through the development of their mathematical mind, language refinement, and sensorial exploration. 



Elementary School

CGMA Elementary School is a continuation of the basic philosophy and principles of Maria Montessori. As the students enter their senior elementary grades and work more abstractly they have gained a greater understanding of the basic concepts allowing them to feel more confident in their own ability to learn.

The elementary classroom is an environment in which our teachers spend much time helping students work cohesively and collaboratively. All students must be contributing members of the class in order to feel comfortable and confident take academic risks, ask questions and present work effectively.

At CGMA students are active partners with their teachers along their educative journey to success.
