The Core Knowledge Preschool Sequence • The Core Knowledge Sequence (K–8)
The Core Knowledge Sequence is a detailed outline of specific content and skills to be taught in language arts, history, geography, mathematics, science, and the fine arts. It represents our best effort to identifty and describe the specific core of shared knowledge that all children should learn in U.S. schools.
Because we say so?
Since our founding over 25 years ago, the Sequence has served as our source document. All of the activities of the Foundation—books, CDs, curriculum materials and professional development--have been aimed at ensuring that all children have access to this rich collection of stories, poems, history, works of art and more.
In an open letter in March 2010, founder E.D. Hirsch announced that the entire Sequence would be made available for free for non-commercial use on the Foundation’s website.
