The site is organized by grade and activities are aligned to the Common Core State Standards (CCSS). Within the navigation the activities are further classified under headings such as Operations & Algebraic Thinking, Number & Operations in Base Ten, Number & Operations â€“ Fractions, Measurement & Data, Geometry. You can drill down further to a specific standard for the grade. Clips can be categorized as SUPPORTS, MEETS or EXTENDS a standard so teachers have flexibility to select activities that suit the mixture of student abilities in their classroom.
