The walls of the left atrium are slightly thicker than the walls of the right atrium. Oxygen-rich blood from the lungs enters the left atrium through the pulmonary vein. The blood is then pumped into the left ventricle chamber of the heart through the mitral valve. From there, the blood is ready to be pumped into the body to deliver oxygen-rich blood to all bodily tissues.
CGMS offers two tiers of training. Full Certificate students attend a residential Montessori training program in addition to their distance learning component. Primary (Early Childhood) level students spend 3 weeks in one summer session. There are two summer sessions for Elementary students.
Children learn best in an atmosphere that combines freedom with self -discipline. True freedom cannot exist without self-discipline and the development of skills for independent thought and action. Freedom in the Montessori classroom means free to do what is right. The child and the teacher work together in a prepared environment to build a community. The child learns to respect the rules. Choice is given for the child to choose his own activity.
