In August I traveled to Escazu, Costa Rica to do math professional development training with The Country Day School. Read the write-up from Katie Matthias-Fandre, Deputy Director of the school. About the School: "The Country Day School was founded by a family in 1963. These pioneers introduced relevant schooling in English for children of expats in Costa Rica. From early days the school's international identity was clear: to provide small classes to students who were interested in an American education and an international pursuit of goals. Today, with high expectations for engaged learning and a culture where students seek personal excellence in every pursuit, CDS helps each community member become responsible citizens for their communites and the world. As CDS continues its over 50-year journey, we value each decade and each learner whose personal story betters our own. With 875 students, over 200 faculty and staff, countless parents contributing daily to the school's legacy and the world around us, wecan only be encouraged, humbled and motivated to keep learning together for the sake of our students' borderless future."
