The School

Lots of light for this new bilingual Montessori private preschool with large windows, located just across the street from the Parc des Bruyères.

The teaching is done in a fully bilingual environment, English/French.

The mix of ages from 3 to 6 years old (petite section, moyenne section and grande section) allows for a stimulating and collaborative learning environment.

Montessori learning activities are carefully selected to support the global development of children from 3 to 6 years old. Other activities, such as plastic arts, hip-hop, musical awakening or baking, complete this program.

Life at 123 mon école


At 123 mon école, lunch is a continuation of the Montessori approach to education, rather than an interruption. Mealtime is an opportunity for children to share and learn the rules and customs of living together with grace and courtesy.

Nap Time

Nap time is for all children in pre-school and first grade.
Organized from 12:30 to 3:00 pm, the children can take the time they need to rest.
Each child has a year-round bed in the nap room, with a sheet and blanket provided by the school.

Parc des Bruyères

Located just in front of the school, this very large park is equipped with many facilities: swings, green areas, slide...

We also organize sports activities here, weather permitting.

Field Trips

Step out of the classroom, go on a field trip, have an adventure!

Every year we organize outings for the children of the school.
This is an opportunity for them to discover all sorts of fun and cultural activities: the Aquarium, the Jardin des Plantes, the Musée en herbe, the Farm, the Jardin d'acclimatation, the theater, etc...


For the pleasure of gathering our team, parents and children, we organize several parties: one for Halloween, one for Christmas and one at the end of the year.
Each year we offer new shows and fun; puppet shows, a cotton candy stand, balloon sculpting and much more.
cotton candy, balloon sculpting and much more to discover!
Parents are also invited to come into the classrooms for a morning of immersion to share a
morning with their child.

Everyone needs time to adjust

At the beginning of each school year, the children
integrate the functioning of the school gradually, at their own pace.
