Tell me about your school. What sort of things do you do there?
Since concepts are taught in many different ways and with many different mediums, children in a Montessori school may not be aware that they are ‘learning”. They often, especially when they are young, think that they are “just having fun”. So if you ask them, “What sort of things do you learn? They may not know how to answer.
Therefore you need to ask them things like, "What sort of things do you do in your school?" or "What are some of your favorite things at your school?"
