The NCTM Illuminations Web site is designed to illuminate the new vision for school mathematics as presented in NCTM's Principles and Standards for School Mathematics.
Goals of Illuminations:
* Provide resources that will help improve the teaching and learning of mathematics for all students.
* Provide resources that bring alive the ideas and recommendations set forth in the NCTM Principles and Standards for School Mathematics (Standards 2000).
* Provide Standards-based resources for classroom use.
* Help communicate the vision of Standards-based mathematics teaching and learning.
