Series | Code | Information

Using this project's list of 1000 k-12 mathematics terms, the terms to the right were used in this book. The terms are in page number order (first page they appear in the textbook at the usage level given). The usage column gives an idea on how the term is being used (refer to the Code section for an explanation).

Please note in this option K-12math.info does not report every time a term is used in a textbook. Only the first page that the term appears on is presented here. This option's purpose is to give a feel for the sequence of content development in the textbook.

The bulk of space used in textbooks is to provide examples of the terms; to define or develop the terms, and to provide exercises using the terms. Different learning communities will provide relevant examples, methods of defining or developing the terms and exercises in accordance to the learning community's needs.
