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.
Hands-on Approach To Learning The use of materials for learning in the Montessori classroom is an integral part of the program from pre-school through the elementary years. Based on a belief that children learn by doing, lessons for math, language and all subject areas include hands-on materials for use by the student.
