To read more about the concepts and design behind CKMath™, we encourage you to dive into the Teacher Implementation Guide for each grade. For example, the Grade 6 Teacher Implementation Guide offers insight into how and why CKMath supports students as they engage with real-world mathematics. The Implementation Guides help to:

  • Clarify the design, research, and format of CKMath
  • Plan the pacing and sequence of activities, lessons, and assessments
  • Support diverse learners, including English language learners, students with disabilities, and students requesting additional challenges
  • And more!

What is yet to come?

We are striving to create a comprehensive Core Knowledge Curriculum Series™ for the elementary and middle grades across multiple subject areas, including Language Arts, History and Geography, and Science. CKMath will include elementary grades K-5 in the future. After the 27 middle school units are completed, our efforts will turn to kindergarten through fifth grade.
