THE SCHOOL PROGRAMME

How children learn at Great Beginnings

The classroom offers children choices within clear routines. Teachers observe how each child learns, then introduce materials and activities that support the next stage of development.

Observe, introduce, practise

Teachers introduce work in response to what they see children doing. Children have time to repeat an activity and build familiarity.

Independence with guidance

Choosing materials and working within shared ground rules helps children take part in the life of the classroom.

An individual and a group experience

Children work alone or with others. Respect for people and the environment is part of the Montessori approach.

INSIDE THE CURRICULUM

Materials, language, movement and discovery

Montessori learning connects subjects with things children can handle, explore and revisit. French, music, physical education and library experiences add to classroom learning.

Learning with materials

Children handle materials and explore through their senses. The teacher observes, introduces an activity and makes room for the child to practise at an individual pace.

Language & early mathematics

Language and mathematics are part of the Montessori classroom. Children can revisit familiar activities and move towards new work as their understanding develops.

Discovery & culture

Science, history, geography, art and music broaden the early-learning experience. Different subject areas give children several starting points for their curiosity.

French, music & movement

French begins in Casa 1. Songs, music, drama and movement support language learning, alongside specialist music and physical-education experiences.

Choice within shared routines

Children choose activities within age-appropriate classroom ground rules. Respect for one another and the environment supports independent work and participation in a group.

Learning with other children

Children work individually or with others. A classroom with different abilities offers opportunities to observe, contribute and learn from one another.
