Green Valley Elementary School (Roanoke, VA). Our school currently enrolls 18 students aged 2 to 5, mostly from economically disadvantaged backgrounds and students with disabilities, in our preschool program. “Tools of the Mind”, the preschool curriculum, is an instructional program that encourages students to strengthen their social-emotional and cognitive abilities while learning at their capacity. Students are engaged throughout the day in theme-based learning centers where they learn skills through play and discussion. This program allows for daily differentiation for each child with conferencing time set aside with an adult each day. Children learn to plan and work together as a team.
