The child is both a hope and a promise for mankind.

Dr. Maria Montessori

Help Me to Do It Myself

The child is assisted in his quest for independence. Your child learns a set of concrete life skills and self-confidence. The order and routine is essential because give opportunity the child to adjust to the environment, understand the world and establish a sense of self and later on – an internal order. Children develop a wide range of motor control and eye-hand coordination through attractive, scientifically designed materials. Special attention is paid to developing the hand and proper pincer grip.

Not a Classroom, a Community

The room looks like a cosy home, shrunk to the size of a very young child. One child may be helping another to dress; a little group may sing with an adult while someone else scrubs a table. The respect and trust given to the children in a constructive atmosphere is naturally reflected by little children interested in what they are doing. Over time, a group of little ones becomes a community. Our children grow together into a caring community. When they work, learn and grow together, the children learn much more than they could learn alone.

A Cosy Environment

This classroom provides a carefully prepared environment where children experience living in a community and participating in activities that support age-appropriate development. The cosy atmosphere is ready so that it encourages activities that foster independence and support language, motor development and “I can” positive self-image. Your child paints, cooks, waters the garden, sings songs with friends and plays with materials that develop fine and gross motor coordination.

Absorbing Language

New language is learned through stories, books, songs, picture cards, and conversations with other children and adults. Dr Montessori’s observations and today’s brain imaging show that the young child’s brain has enormous potential and promise. Within their first six years, children develop from having no verbal language to fluency in their native language. The toddler environment supports this tremendous growth through language nomenclature cards, books and spoken vocabulary enrichment exercises. Child absorbs the surrounding and spontaneously can learn to speak more than one language.

Freedom of Movement

This is when the child is absorbed in the control and refinement of movement and language development. Gross and fine motor skills develop competence, self-esteem and independence. Our environment is designed to meet his needs for love, order and as much freedom as he can handle at any given time. It responds to the children’s physical needs and their love of movement.

First Friends

Making first friends and learning how to function within a community is a life-shaping experience for your child. Your child emerges with solid friendships that will continue as she moves through the rest of the programs at Otkrivatel.

A Joyful Experience towards Independence

“One test of the correctness of the educational procedure is the child’s happiness,” says Maria Montessori. The toddler is given opportunities to explore their independence and connection to the world using their extraordinary capacity for learning. New parents are often surprised to see the peaceful tone of our toddler classroom and the joyful and engaged little children. The calm atmosphere and lack of distraction help the child to develop impulse control and concentration, planting the seeds for learning in this classroom and beyond.


To be a toddler is to be curious. There are many things to see, touch, hear, feel and do in the classroom! We know that nothing that does not come through the senses is processed through the intellect. Patterns and repetition tendency play significant role for stimulating the brain cells development. We assist your child in training the senses during the most formative years to excel later through education of specific skills. Your child develops the belief that she can choose to make a genuine impact on her world.

Ready to Move Up

Sometime around 3 years, your child’s language skills will develop rapidly; he will express a growing confidence in independence and a keen interest in broader concepts; he will want to know what lies outside the Toddler Classroom. At this point, he is ready to move up to the Children’s House, for children from the ages of 3 to 6.

Dani is extremely independent, We got rid of the diaperf in two days. I can surely say theat Otkrivatel was the best choice for Dani’s development. Thank you so much to the entire team!

A mother

At Otkrivatel Children’s House and more specifically the Toddlers community we not only found а good relationship, but also real friends! It is very important for us for Silvia to receive individualised approach that will support her in her development in the best way possible. Silva is very happy to attend the Children’s House, she develops new skills and is able to transfer her knowledge at home. The Montessori Method develops the child’s independence and is based on the child’s plane of development, it supports the willingness and creativity of the child. The child has the freedom to choose the materials they want to work and experiment with. The Children’s House has a fantastic backyard with slides and swings, where the children not only have fun, but also plant flowers and other plants, take care of them and observe them growing. Polite, calm and attentive – the guides are always next to them to help them do the work themselves! They are the same way with us – they take time to guide us and give us advise on how to understand our child and support them to develop their full potential. Thank you!
