The Illuminations website is always growing in order to bring you the best mathematics education Internet resources. Listed below are the latest additions to the site and site construction announcements.

Exploring Geometric Solids and Their Properties - The interactive tools in this i-Math investigation are designed to allow students to explore geometric solids and their properties.

Welcome National Council of Teachers of Mathematics convention participants.

The Next Billion - Students predict when the world population will reach 7 billion. (Grades 6 - 8)

Five's a Crowd: A Game of Population Density - Students play a game in which they try to list 5 countries or states in order from most crowded to least crowded.

Principles and Standards:

-- The final version of the Principles and Standards for School Mathematics (Standards 2000) was released at the NCTM Annual Conference in Chicago. Our Principles and Standards page links directly to the new standards.

New Navigation System:

-- Our entire site has been completely redesigned for easier navigation. Go through the site by grade band or content with the new navigation bar that is on the top of each page.

i-Maths Investigations:

-- Students i-Math Investigations for classroom use. This one page contains a listing of all specially-formatted i-Math Investigations for classroom use. School computer labs only need to bookmark this one page to allow easy access to all our ready-to-use, online interactive, multimedia math lessons. All unnecessary navigation off the site and teachers notes (where applicable) have been removed from our student i-Math Investigations.

-- Netscape Navigator support has been added to all i-Math Investigations.
(We recommend Macintosh users continue to use Internet Explorer.)

Reflections on Teaching:

-- This new section has been added to the site to provide reflection activities based on video vignettes of teaching and learning.

Welcome page:

-- Our homepage now loads incrementally, welcoming our users to the site! We have placed all the most important links and buttons at the top of the page for quick and easy access.

Eisenhower National Clearinghouse For Mathematics and Science Education gives teachers a plethora of educational information, resources, and activities across all grade levels.

Using Algebra and Discrete Mathematics to Investigate Population Changes in a Trout Pond - This investigation illustrates the use of iteration, recursion, and algebra to model and analyze a changing fish population. Graphs, equations, tables, and technological tools are used to investigate the effect of varying parameters on the long-term population. (Grades 9 - 12)

i-Maths:

--Many of the i-Math applets currently run only under Internet Explorer. Netscape Navigator access will be added soon. (see above)

--All i-Math Investigations will eventually have both student investigations and teacher notes with professional development activities. For now, some have only one or the other.

Principles and Standards:

-- The final version of the Principles and Standards for School Mathematics (Standards 2000) will be released by NCTM in April 2000 at the NCTM Annual Conference in Chicago. Until then, this section of the Illuminations site links to the Discussion Draft of the Principles and Standards. Links to NCTM Standards from other sections will not all be active until the release of Standards 2000 in April.
