Attention of 0-6 years old. Montessori believes that children at this stage are characterized by absorbing everything. Children aged 0-3 absorb their minds unconsciously, while children aged 3-6 absorb their minds consciously. At this stage, children absorb all the information in their surroundings effortlessly. They don't analyze, don't distinguish symptoms, and don't consider causes and consequences. They use all their senses to absorb, which is why there is a special area in the Montessori classroom of 3-6 years old, that is, the "sensory area". Another feature of children in this period is that they are more interested in real life.
