Nursery and Preschool

Learning while playing

Our Nursery and Preschool students discover knowledge through active learning experiences and develop their personality in a safe and stimulating environment. They become competent and enthusiastic learners, while they develop social skills.

In our program they learn while playing in individual and team activities and they make connections between the classroom and their daily lives. Our students’ first contact with technology enhances their learning. The instruction is given entirely in English, except for the Physical Education and Spiritual Growth classes.

Their first contact

Our Nursery program is the student’s first contact with school and is fundamental for their academic and personal success. Our small groups of 12 students are key to help our students learn while they play in an environment where they feel safe.

Discovering their potential

Our Preschool program focuses on creating a learning environment in which each student explores their environment, builds significant learning, and discovers their own potential.

We emphasize literacy skills, numeric concepts, and social and personal abilities, including personal working habits.

Readers and writers for life

Our Balanced Literacy program promotes an environment rich in language, which stimulates student participation in paired, reading, group reading, and paired writing experiences, which guides them towards independent journalism writing.

Everyday mathematics

The Everyday Mathematics program is practical. Our students learn about numbers, operations, patterns and functions, geometry, measurements and data via exploration activities.

Habits of Mind®

Using the Habits of Mind® program we promote reflection, perseverance and mental skills to ensure that our students are making smart decisions.
