In the Montessori classroom space is divided into several logical parts using low open shelving: one shelve is for practical exercises from life, one for sensory perception, one for the language, another one for counting and arithmetic, the study of culture, which includes the basics of geography, history, science and a section dedicated to creative activities.
Montessori curriculum is an integrated thematic approach that combines separate events. Each lesson builds on many others. Each material in an environment is designed to be attractive to children and is focused on one learning concept or skill.
Most of the material has an internal mechanism that allows checking for the errors. The child is capable to check on their own work without having to depend on an adult. Montessori children learn that they do not have to worry about making mistakes. They quickly discover that they can try everything again without fear or embarrassment.
Materials are used as tools to help children work and learn at their own pace, perceive abstract ideas presented in a very concrete three-dimensional way, and help them understand what they are working on.
Spacious classroom is adapted to children of different ages. In this environment, children can learn from each other. Younger children are familiar with new concepts, but also deepen their knowledge "admiring" older children, who consider inspiring the fact that they can share their knowledge with the younger ones.
