fbpx Middle School


The Middle School Section is made up of students belonging to grades 4, 5, 6 and 7 and whose ages are between 10 and 14. Our students are wonderful boys who begin to experience new changes from their emotional development , physical and social, eager to learn and find meaning in all the challenges that life presents them, because it is during this time that they struggle to define themselves as individuals and in relation to others. They begin to question the role of adults in their lives, and their peers become increasingly important.

Friendship and companionship relationships are present in all their projects and we want to support them so that in La Arboleda they achieve all their dreams.



Development of critical thinking

Colegio La Arboleda frames its pedagogical approach within Active Learning, which seeks that each student build their knowledge from a repertoire of strategies that facilitate their learning in a collaborative relationship and in full conjunction with the values ​​of the school: respect, responsibility, love, commitment and sense of belonging.

Family and School

Walking the path of the Middle School ages, the family and the school play a very important role in the process of training children. You can see an enthusiastic community ready to face the challenges that arise day after day with the aim of providing children with the best possible education at all levels.

Being individual and sociable

Defining character and establishing cordial relationships with peers becomes the challenge of an adolescent, who with his bright smile seeks to open a valuable space for his emotional development and for the fulfillment of his goals on the path of cordiality, commitment , compassion and academic excellence.
