Setting up a Montessori classroom floor plan for children ages four to six can be challenging, especially if you are a first-time teacher or returning from summer vacation. With this Montessori classroom floor plan, the trick is to make it cute, efficient, and a safe and appealing learning environment. Kindergarten classrooms must first and foremost be secure. Classroom setups are subject to rules, guidelines, and regulations. These can also differ from country to country, as will the licensing body or accrediting institution.
