Tool NCTM Illuminations


This site is designed to illuminate the vision for school mathematics described in NCTM's Principles and Standards for School Mathematics. The examples contained within it span the entire K-12 range. This resource includes:
  • i-Maths: online, interactive, multimedia math investigations. All i-Maths are built around interactive math applets, and some also include video clips.
  • Internet-Based Lesson Plans showing how the Internet can be used to help create effective Standards-based mathematics lessons.
  • Math-lets: math applets you can download and use to explore math and create interactive lessons on your own.
  • Inquiry on Practice: video vignettes, research reports, and articles designed to encourage thinking and discussion about how to improve the teaching and learning.
