• Children had episodes of deep concentration and several repetitions of the same activity.
• Given a choice, children showed more interest in practical activities and materials than toys, sweets or other rewards.

The goal is to grow children to become independent and responsible adults.

Montessori's ideas started spreading through the world to inspire progressive thinkers and educators around the world. 

Later alumni include Jimmy Wale from Wikipedia, author Gabriel Garcia Marquez, Larry Page and Sergey Brin.

Today, many educators use the insights and material inspired by Montessori. Some parents use it for homeschooling.
