Why The Children’s Tree Montessori School?

We Emphasize More than Just Academics

We honor your child’s individuality and focus on curiosity, independence, compassion, collaboration, and critical thinking, preparing him or her to take on the future with confidence, propelled by the gift of self knowledge and a passion for learning.

…but the Academics Are a Huge Strength. 

It is not uncommon to see four-year-olds in our school reading, six-year-olds completing long division problems, and nine-year-olds classifying botanical specimens. The Montessori curriculum presents skills at the time when children are most ready to learn.

We’re a Community.

Our independent school is a community for more than just childcare. We view our relationship with you as a partnership, working together for the benefit of your child. Because children thrive when home and school work in harmony.

Rivers are so important to our human story. They are sources of nourishment, transportation, and connection. We see how children are naturally drawn to water, and rivers offer a powerful way to understand ecology, interdependence, and our place within the natural world. With this in mind, we want to share some of our favorite books about water, rivers, and watersheds. Through story and illustration, children can trace the journey of a single drop of water, observe how land and water shape one another, and begin to understand how human choices affect the health of our planet. We’ve grouped the following collection of river and water-focused books by developmental stage. Each title offers language, beauty, and meaningful context for deeper exploration. Whether you are reading with a toddler, a younger elementary child, or an emerging researcher, these books invite wonder, responsibility, and reverence for one of Earth’s most essential elements. For the Youngest Hey, Water! By Antoinette Portis This picture book takes us on a journey of how water is part of our lives in so many ways: from sprinkler spray to a teardrop trickling. The clean-lined illustrations transition between bird’s-eye views and close-up images. This is a great transition book for toddlers moving from pages with one word labeling a picture to a narrative that connects to daily experience. A Place for Rain By Michelle Schaub, Illustrated by Blanca Gómez A lovely introduction to the concept of rain gardens, this picture book follows a simple story of children witnessing how rain runoff can be transformed from being problematic into something stunning and special for everyone. The sweet, slightly geometric illustrations highlight how even simple actions can have a big impact. Water Is Water By Miranda Paul, Illustrated by Jason Chin Although a picture book about the changing states of water, the lyrical text and charming illustrations make this a delightful and fun-filled page-turner! It’s a great way to introduce young children to the water cycle and the importance of water in our lives. Water Cycle: For Younger Elementary Drop: An Adventure through the Water Cycle By Emily Kate Moon Bridging between comic style and traditional picture book, the story follows the character, Drop, as she travels through the water cycle. Delightful and engaging, this is a great book for younger elementary children and can serve as an easy-to-access resource for understanding the states of water. A Drop Around the World By Barbara Shaw McKinney, Illustrated by Michael S. Maydak Written in rhyming verse, this story follows Drop from a cloud near Maine around the world and back to Cape Cod Bay. A map inside the cover shows the journey, and emoji-style images accompany the text, linking to more detailed descriptions of the amazing science at each step along Drop’s path. Watersheds If the Rivers Run Free By Andrea Debunk, Illustrated by Nicole Wong This captivating picture book takes readers through the human story of rivers’ importance in our lives, the mistakes we’ve made, and how we can make things right and help rivers run free again. The rhythm of the text is accentuated by moments of human realization, with bold statements that step out of the rhyming pattern and gently jar us into a sense of action. The illustrations take readers on a journey, too! One Well: The Story of Water on Earth By Rochelle Strauss, Illustrated by Rosemary Woods Through its clear text and lush illustrations, One Well emphasizes the interconnectedness of water on our planet. It offers an array of interesting information that will appeal to children in elementary years, both through narrative text and short snippets overlaid on the images that fill each page. The fact that this picture book has an index is an indicator of how just how much its 32 pages contains! River Story By Meredith Hooper, Illustrated by Bee Willey Rich in realistic content yet engaging and accessible, this lushly illustrated picture book takes readers on a journey from the source of the river to where it empties into the sea. Watersheds: A Practical Handbook for Healthy Water By Gregor Gilpin Beck, Illustrations by Clive Dobson Best for older readers, this book offers helpful and non-technical information about watershed concepts and environmental concerns. This is an excellent resource for older elementary or younger adolescents engaged in ecology research. The illustrations are beautiful, too! We’d love to hear what you think about these books! You can also download a printable list for the next time you visit your local bookstore or library! Also, feel free to schedule a visit here in [Your Town/Location] to learn more about how the story of water flows through children’s lives!

For many of us, we remember learning long division as a confusing sequence of steps to memorize and repeat (bring down, divide, multiply, subtract), often without a real sense of why it works. In Montessori classrooms, long division unfolds very differently. Through the Racks and Tubes material, children get to experience what division actually is. Two Ways to Divide: Sharing and Grouping Before introducing the material, we first clarify an important idea: there are two different kinds of division problems in real life. One asks, “If I share this equally, how much does each person get?” This is partitive division, or division by sharing. The other asks, “If I make groups of a certain size, how many groups can I make?” This is measurement division, or division by grouping. The Racks and Tubes material focuses on partitive division. Children physically share quantities equally and discover what one share receives. Materials like the Stamp Game emphasize division of measurement. Together, these approaches give children a complete understanding of division and help them choose the strategy that best fits a given problem. What Are Racks and Tubes? At first glance, the material is impressive and a little mysterious. Children are often drawn to the material, both for its beauty and its seeming complexity. Racks hold test tubes filled with beads, carefully color-coded by place value: units, tens, hundreds, thousands, all the way up to millions. Matching cups hold the dividend (the number being divided). Boards and skittles represent the divisor (the number doing the dividing). Every detail of the material reinforces place value. Each time children need to make an exchange, they trade in one bead of one category for ten of the next category (e.g. one hundred becomes ten 10’s). This process is visible and incredibly concrete. This material takes intentional focus. It takes time. And it makes the steps of long division clear. How Long Division Becomes Concrete When children solve a division problem with Racks and Tubes, they follow a logical, embodied process: They build the dividend using the racks and cups. They represent the divisor with individual figures on boards. They share beads one at a time, equally, to each part of the divisor. They stop when sharing is no longer possible and then see what remains from that category. They then bring down the next category of beads to continue the sharing process. Each step answers a real question: What does one unit get? What happens when we run out? What do we do with what’s left? Instead of being told “bring down the next digit,” children literally bring down the next category of beads. When exchanges are needed, they perform them physically by trading beads. Remainders are not mysterious leftovers. They are beads still sitting in the cup. Long division becomes a story children can follow. From Material to Abstraction One of the most beautiful aspects of this work is how naturally it leads into abstraction. At first, children record only the quotient. Later, they begin recording intermediate remainders. Eventually, they discover that multiplying the quotient by the divisor tells them how much has been used at each step. This is the very heart of the traditional algorithm. We don’t give abstract shortcuts. Instead we help children discover the pattern. This allows them to own the process. By the time children are working abstractly on paper, the algorithm already makes sense. It matches what their hands have done again and again. Why This Matters The Racks and Tubes material does more than teach division. It teaches: Deep place value understanding Logical sequencing Patience and precision Trust in one’s own reasoning Most importantly, it gives children confidence. Division is no longer something done to them. Instead, they can think through the process, step by step, with meaning and understanding. In Montessori, math is not about getting the answer quickly. It’s about building an understanding of why the process and answer makes sense. And with Racks and Tubes, long division finally does!

In Montessori, we often focus on how the environment educates the child, but just as powerful as the physical space is the presence of the adult within it. For children in the first three years of life, adults are not simply caregivers or teachers. We are models of movement, language, emotional regulation, and relationships. Being present with young children is about being present in a different way. From Birth to About 14 to 16 Months Infants are forming their earliest understanding of the world and of themselves. They observe everything! So the adult’s role requires a quiet strength and a deep level of self-awareness. To be present with infants, we must love without expectation. Infants are not able to return affection in predictable ways, and presence cannot be dependent on feedback or validation. This work requires patience, generosity, and emotional steadiness. Movement also matters deeply at this stage. Infants study how adults walk, reach, sit, and handle objects. Slow, intentional movement gives children something meaningful to absorb. When adults rush, babies feel it, even if they cannot name it. Our language, too, must be precise and respectful. Clear enunciation and specific wording help infants build an accurate internal map of their world. Vague language like “that” or “over there” offers little clarity. Instead, we want to name what we see and what we are doing: “I am placing the cup on the table.” Infants cry as their primary form of communication. Being present means responding without panic or frustration, and making thoughtful decisions even when there are multiple demands on our presence. Emotional regulation in adults becomes a sense of emotional safety for the child. Dynamic Toddlers As children grow into toddlers, our presence still needs to be very intentional, yet it also becomes more dynamic. While toddlers are building independence, they still need deep connection. For adults, this means remaining loving without demanding affection or closeness. Even physical affection requires consent: “Would you like a hug?” or “Do you need some comfort?” Respecting children’s autonomy builds trust and self-awareness. This stage is full of transitions, especially for children navigating new siblings, new communities, or a growing awareness of others. Sometimes toddlers want to be capable and independent. Then sometimes they want to be cared for like a baby again. Presence means honoring both without pushing the child prematurely in either direction. Limits are a key expression of presence. Clear, consistent boundaries create structure, and structure supports independence. A few simple rules, maintained calmly and consistently, help children orient themselves in the world. If power struggles emerge, we can use them as opportunities to reflect on control rather than behavior. If children have tantrums, presence means staying close without escalating. During the height of anger or upset, we may simply ensure safety. When a child moves into sadness or overwhelm, we can offer comfort and reassurance. The goal is not to stop the tantrum, but to support a child through it. Flexibility is another essential part of presence. Although routines give children a sense of security, rigidity can disconnect us from their real needs. Sometimes the best choice is to go outside, to move, or to shift the plan. When children feel secure, they can adapt, and so can we. Finally, presence means embracing life alongside children. Young children notice the world with fresh eyes. Weather, seasons, light, and movement all become sources of joy and wonder. When we allow ourselves to feel awe again, children experience validation that life is something rich and meaningful. Our Inner Work Being present with young children is demanding, not because of what children require, but because of what we must bring: patience, humility, emotional regulation, and a willingness to slow down. This work invites us to become more aware of ourselves: our language, our pace, our reactions, and our assumptions. In doing so, we offer children not just care, but a living model of how to be human in relationship with others. Presence is not perfection. It is mindful attention. And for young children, that attention becomes the foundation upon which everything else is built.
