Learn how the Horizons National network promotes summer learning in this video from American Graduate Day 2014. “Summer Slide” describes the loss of reading and math skills that often happens during the summer months when school is out. This phenomenon disproportionally affects low income children. The Horizons program combats summer slide by providing students with academic practice, physical activities, and enrichment activities. Use the “Summer Learning Guide” in the Support Materials to help turn everyday activities into learning activities that keep academic skills sharp outside of school.
