SpaceMath@NASASpaceMath@NASA introduces students to the use of mathematics in today’s scientific discoveries. Through press releases and other articles, we explore how many kinds of mathematics skills come together in exploring the universe. Problems include everything from estimating the amount of time it will take the Opportunity Rover to travel around different features of Mars (grades 6-8) to calculating the volume of a comet’s head (grade 12). Over 390 archived problems are available, with more being created regularly!

High School Operations Research**Real-World Modules for Use in High School Classrooms**

Since 1996, we have developed thirteen instructional modules for use in high school mathematics classrooms. Each module develops secondary mathematics concepts in real-world contexts drawn from the field of operations research. These applications span the spectrum of organizations: from Bethlehem Steel to Ponderosa Plywood of Mexico, from Hertz to HP, from routing Meals-on-Wheels to routing Special Ed school buses. The activities build on the basic math concepts that all high school students study in algebra and many see in an introductory probability or discrete mathematics course. They are aligned with NCTM's Principles and Standards.

National Council of Teachers of Mathematics Illuminations**Teachers of all levels**

At this site, you can learn about NCTM’s Principles and Standards for School Mathematics, and explore a library of 102 online activities that help to make math come alive in the classroom or at home, view a collection of 584 lessons for preK-12 math educators, and check out hundreds of exemplary online resources, as identified by an editorial panel. All are aligned with NCTM's Principles and Standards.

The National Library of Virtual Manipulatives (NLVM)**Teachers of all levels**Mathematics is not a spectator sport. Too much of current instruction fails to actively involve students. One way to address the problem is through the use of manipulatives, physical objects that help students visualize relationships and applications. We can now use computers to create virtual learning environments to address the same goals.The NLVM is a resource from which teachers may freely draw to enrich their mathematics classrooms. The library is actively being extended and refined through projects including the eNLVM, a project to develop interactive online learning units for mathematics.
