Core Knowledge History and Geography

Core Knowledge History and Geography™

A comprehensive program in world and American history and geography, integrating topics in civics and the arts, Core Knowledge History and Geography™ (CKHG) helps students build knowledge of the diverse civilizations, cultures, and concepts specified in the Core Knowledge Sequence.

CKHG for Social Studies or Language Arts


For Social Studies: Used in their recommended sequence, CKHG materials can form the basis of an engaging Social Studies program that builds historical and geographical knowledge and skills grade by grade.

For Language Arts: You can also use CKHG to integrate content-rich nonfiction into your Reading/Language Arts lessons. CKHG objectives are correlated with the Common Core English Language Arts standards, which call for increased reading of nonfiction informational texts. With CKHG, you can take an interdisciplinary approach to reading that provides rich, meaningful, and sustained engagement with informational texts organized in a coherent sequence.

CKHG Components

  • Student Readers: richly illustrated and engagingly written
  • Teacher Guides: with detailed lesson plans, activity page masters, additional activities, and assessments
  • Timeline Cards: visual aids to reinforce big ideas, chronology, and context

Are printed books available?
For those seeking individual printed volumes, many titles will be available for purchase in our Store by mid-June. While we arrange to print CKHG books, we want you to have access to the downloadable versions now.

Some units in CKHG seem similar to topics in CKLA (Core Knowledge Language Arts). If we are using CKLA, should we skip the comparable CKHG unit?
Between the two sets of instructional materials (CKLA and CKHG), there is some intentional overlap in topics, but in each series students read completely different text. Reading different texts on the same domains during the language arts and social studies blocks can give students greater opportunity for frequent, repeated exposure to domain vocabulary and concepts, thereby reinforcing learning.

Can the units be used only at the specified grade levels?
CKHG units are correlated to topics at the grade levels specified in the Core Knowledge Sequence, which allows students in schools following the Sequence to build knowledge grade by grade. In other settings, individual CKHG units may be used as supplemental resources. In general, the content and presentation in the CKHG units for Grades 3-5 are appropriate for young readers from the upper elementary grades through middle school.
