Hi, we are glad you are here. We at Montessori Research and Development (Montessori RD) have been providing the Montessori community with Montessori curriculum materials and Montessori teacher manuals for more than four decades. We are the pioneers of now standard classroom materials such as the Word Study and Geometry, Botany, and Zoology nomenclature sets.

The Fundamental Needs of Humans

We, the people, live in this world made from our billions of ancestors. Our history is not the result of kings and battles, although they shaped us. Our history is the struggles and triumphs of all people to meet their fundamental needs. These needs, common to us all, express themselves differently across time and place. People have coalesced into communities, which have given rise to civilizations.

Our Sensorial manual has been read by tens of thousands of Montessorians around the world. After 35 years, it is still the to-go manual for teacher training centers in the USA and abroad.
