CK-12.org kindergarten through fifth grade math textbooks - a view by k-12math.info
Information

Since information is the foundation for development and there seems to be a reluctance by Ck-12.org to round out their sixth through secondary school mathematics textbook series, k-12math.info would like to propose the following. A look at what content, content distribution and how the content could be developed for the "missing" kindergarten through fifth grade mathematics textbooks that would blend with their existing textbooks.

The mathematics terms (or their synonyms) that are used in the following spreadsheets are part of the lesson proper. Lesson proper means the explanation or the development of the terms through an interaction between teacher and learner. In learning communities where written textbooks exist, the interaction is aided by a written explanation using the terms.
