Sun Valley has been implementing Everyday Math (EM) curriculum since 2008 and is currently using the latest Common Core correlated version.  San Rafael City Schools adopted EM because of its effective use of mathematical strategies to build a strong foundation of mathematical understanding. Each day in our classrooms, lessons are being linked to math everyday experiences, connected to past lessons, include hands-on activities, and build foundational skills through oral practice and games. An instrumental part of the curriculum is encouraging students to share their thinking and problem solving approaches. The scope and sequence of the curriculum is designed with a spiral approach that exposes students to concepts and then revisits the same concepts throughout the year.
