Montessori Quote
By exercising control of error when working with the apparatus, the child’s mind is held by the apparatus. If he replaces the cylinders incorrectly and there is one cylinder left without a cavity he will be inclined to wonder why there is still one cylinder left. Why? Although he does not reason exactly as we would, he realises it subconsciously through his actions.
Maria Montessori, The 1946 London Lectures, p. 82
