Best Practices: Montessori Materials Learning materials are attractive, crafted from natural materials, and support independent exploration of academic concepts. These qualities apply to the materials in the Montessori curriculum and to items used in practical life activities at all ages. As the children reach the upper levels of our program, their work in a wide variety of disciplines is supported by technology and textbooks as well as the low-tech materials required for hands-on learning in science and permaculture.
