Curriculum Materials:  How to Think, not What to Think…..

Project Learning Tree is a national,  award-winning environmental education program designed for teachers and other educators, parents, and community leaders working with youth from preschool through grade 12.  Materials are created by teams of teachers, curriculum specialists, natural resource professionals and industry experts, and are then pilot tested in real classrooms.  As trends and standards in Prek-12th grade change, so do our materials and programs.  21st century skills have been embedded in our activities since the 20th century! Our activities have always been student-centered,  inquiry based,  interdisciplinary, cooperative and constructivist!

PLT provides curriculum materials and additional resources for  educator across the curriculum.

The CO PLT Early Childhood program, Environmental Experiences for Early Childhood, has earned TTASC approval (Trainer/Training Approval System of Colorado) for Qualistar and is a Colorado Department of Education approved Early Childhood Training!   

The activity guide is available in Spanish.  (Proyecto Aprendiendo del Árbol: Experiencias ambientales para la primera infancia)
