S.A.N.D. School students engage in their Common Core aligned, language arts curriculum using Literacy by Design or Expert 21. In Grades K-5, teachers and students use Literacy by Design, a balanced literacy curriculum that is built on the gradual release of responsibility model with explicit whole group instruction followed by differentiated small group instruction. Grade 6-8 students use Expert 21, an English Language Arts curriculum that focuses on inquiry-based learning through interdisciplinary literature and informational text and real-world application of reading and writing. Literacy by Design and Expert 21 provide a highly organized classroom structure where students apply concepts and skills from whole group instruction in small groups or independently within differentiated learning centers. Learning centers may include a poetry center, a listening center, a writing center, a fluency center, a phonics center, or a drama center to provide students with depth of understanding of the piece of literature or the theme in their unit of study. Waterford, SuccessMaker, iReady, and Read 180 are technology based literacy intervention programs that are used at S.A.N.D to assist students who are currently not meeting grade-level expectations to close the achievement gap. Numeracy core instruction is implemented through the use of enVisions whole group and small group differentiated math stations. Students are provided with daily problem-based interactive mathematics that is aligned to the Common Core State Standards. Waterford Math, iReady, Fastt Math, and enVisions Online are some of the math technology components used to support the curriculum. Positive Behavioral Interventions and Supports, or PBIS, is built into the school community and instructional system to ensure that all students are engaged in a productive learning environment.
