Exploring The Core: Elementary Math is the best way to *see* what is in the Common Core State Standards for Mathematics. Our math app presents all CCSS standards in Mathematics for grades K-8, illustrating each grade-level skill and aligning to show skill development across grade levels. With this app, teachers and parents can not only read the Common Core State Standards for each grade-level skill, but can also "swipe" to see how each skill develops in and between grade-levels. Searchable Standards and Glossary features eliminate the need for lugging heavy binders of standards and education-specific references around with you. Created by a teacher for teachers and parents, Exploring The Core: Elementary Math is the perfect tool for anybody wanting to understand the basic skill sets expected in the Common Core State Standards. This app serves as a reference tool for parents and teachers. It is not a curriculum and is not intended to serve as a primary teaching tool for students.
