“Participating in the League for Green Leaders competition this September was a fun, engaging, and educational experience for my Grade 4 and 5 students. Along with eco-literacy, the activities incorporated elements of science, social studies, and math.”

“Your program is highly engaging to students, in particular to one student whose mother emailed me and told me that he had difficulty engaged in regular classes, but spent so many hours in the League for Green Leaders competition.”
