What the Hand Does, the Mind Remembers


“What the hand does, the mind remembers.” – Dr. Maria Montessori


Children remind me that they learn with their hands, something Dr. Montessori understood through quiet observation over a century ago. This continues to be true in the current time of digital technology (literally: tools used by the hands) and an adult focus on abstraction as a metric of success. I have grappled with the inclusion of technology and testing in the Montessori classroom, in both private and public charter environments, and I continue to believe that they are incongruous with the beautiful and patient process of a child learning by holding actual objects – clay, fossils, fern fronds – with their hands.

“Do not tell them how to do it. Show them how to do it and do not say a word. If you tell them, they will watch your lips move. If you show them, they will want to do it themselves.” – Dr. Maria Montessori

A few years ago, I asked a mother of one of my students to come in and demonstrate how she makes her own kombucha. There were simple ingredients and a live bacteria, which we stored in our room for weeks and watched grow, documenting its bubbling surface and the layers that it formed in a controlled environment. It is much easier to just buy a bottle of kombucha at a store, however the children looked forward to being a part of the process – using gloves to touch the SCOBY, selecting the flavors to add. Convenience is not always possible nor preferable. It often stalls understanding.

"The senses, being explorers of the world, open the way to knowledge." – Dr. Maria Montessori







In the Montessori learning environment, especially the expansive Cosmic Curriculum, there are many varieties of concrete materials – from the wooden Bohr diagram modeling the inside of an atom to the Timeline of Life with era boxes full of fossils to the Land and Water forms (used with colored water poured from a jug). Many of these initial materials have extensions which allow interested children to go deeper. For example, many children choose to make their own Land and Water booklet with brown and blue paper, or (in this case, shown above) models formed by painting dried clay models.

When I think about the ways in which public education (and, often, adult thinking in general) prioritizes large quantities of superficial, one-time-only lessons – some of which are never reviewed nor returned to – I feel thankful that Montessori education functions in the exact opposite manner. Children are encouraged to go deeper, to be reiterative, to be creative with a concept, making the trench of the neural pathways surrounding it that much further ingrained.

“Education is a natural process carried out by the child and is not acquired by listening to words but by experiences in the environment.” – Dr. Maria Montessori



Children learn about Parts and Kinds in Montessori education, from math to language to science:

Parts of the Atom and Kinds of Atoms

Parts of a Line and Kinds of Lines

Parts of Speech and Kinds of Words

Children are attracted to the largest things and the smallest things. When we study the Coming of the Earth, we find an inter-relatedness with the Inner Earth and the Plate Tectonic activity that caused and causes land forms to exist, that allowed animal and eventually human migration to occur. Children are fascinated by superlatives: the highest, the furthest, the smallest, the coldest, the hottest. Again, it would be easier to simply purchase a model of a volcano from a craft store. However, witness these children forming volcanoes with their own hands!

“The hands are the instruments of man’s intelligence.” – Dr. Maria Montessori




It is amazing to be alive, and children in Lower Elementary also come to a knowledge that death is something that belongs to all things. We study life cycles of living things, such as a tree or a jellyfish, and we also know where our Universe is in its own lifespan. (Like me, it’s middle-aged!) This knowledge of the ephemeral quality of nature is deepened when children see the Timeline of Life, specifically how old the world is, how old other organisms are (like the jellyfish, one of the longest lived creatures on the planet), and how young we humans are as a species. When we study the life cycle, we see the same phases and know that each organism is unique and special.

“The human hand allows the mind to reveal itself.” – Dr. Maria Montessori



One of the most inspiring things to see is what children create from their own imaginations. When they use geometric building blocks as a Practical Life activity, they are resting their reading mind and engaging their body – their kinesthetic and tactile intelligences. They are using the concept of gravity when they balance an arch on a cone. They are using the concept of symmetry when they build a structure out of rectangular prisms, pyramids, and cylinders. Mainly, though, they are free to experiment, make mistakes, try again, and eventually hopefully innovate while creating an architecture of their own happiness.

The Earliest Life Forms on Earth



Montessori’s Great Lessons give the universe to the child and encourage discoveries. After the expansive First Great Lesson: The Coming of the Universe (which incorporates astronomy, chemistry, and physics), Montessori 6-9 year-old children explore the Second Great Lesson: The Coming of the Earth. In addition to hearing stories from various cultures around the world about how our planet came to be, children are also told the evolving story of the Earth’s history as told by the scientific community through facts, evidence, and the Scientific Method.


The Second Great Lesson: The Coming of the Earth incorporates geology, physical geography, and biology. The life sciences shine during this curricular study of the earliest life forms on the planet. Having explored the smallest particles of matters, atoms, in the previous Great Lesson, here children learn about kinds of cells – prokaryote and eukaryote – which led to bacteria such as protists and early plant life in the form of cyanobacteria. 



In my current Montessori-hybrid charter environment, we explored cell structures – their parts and how they function, as well as how they differ. One of the most popular lessons I give involves using egg yolks and a fork to discriminate between the two main kinds of cells.


Children are motivated to read about and identify the parts of the cells using three- or four-part card Zoology materials. (Three-part cards feature an image, a label, and a combined image and label card. Four-part cards are mainly used in 6-9 and 9-12 learning environments for children with advanced decoding and reading comprehension skills.) After learning about prokaryote and eukaryote cells, children investigate which kinds of living things contain these kinds of cells. They then may choose to make models with objects representing different parts. These extensions deepen and broaden connections children will later make when they concern themselves with more advanced life forms.


As we move into the Timeline of Life that began with the Proterozoic Era of Earth History, children lay out the timeline (color-coded by era). 


They see just how long one main life form – the cnidarian (one example of which is a jellyfish) -- existed virtually alone on the planet, evolving and adapting as the world became cleaner due to adaptations of plant and animal life filtering the air and water of acid rain produced by volcanic off-gassing. 




These invertebrates paved the way for later animal forms to create skeletons and become vertebrates, and they remain some of the longest life forms in existence, due in large part to the gift they made of their bodies for the lives of others.
