Academic Standards Reference

Browse Common Core academic standards by subject and grade, each paired with a real, teacher-created lesson sample.

The Common Core State Standards (CCSS) describe what students should know and be able to do in math and English language arts at each grade level, from kindergarten through 8th grade.

Every standard on this site is paired with a real sample lesson, not a definition alone, so parents and teachers can see what mastering it actually looks like.
