Algebasics is an free, online mathematics instructional resource that takes a middle school, high school or adult learner through the basics of algebra. The material is divided into sixteen sections, which begin with, "the basics," and includes a section on applying algebra to real-world situations. This is an audio resource with web display, so computer speakers must be turned on to use this site. This site covers basics, equations, ratio and proportion, inequalities, absolute value, exponents, polynomials, factoring, rational expressions, rational equations, linear equations, functions, systems of linear equations, radicals, quadratics and applications. http://www.algebasics.com/

AMSER (the Applied Math and Science Education Repository) is a portal of educational resources and services built specifically for use by those in Community and Technical Colleges but free for anyone to use. AMSER is funded by the National Science Foundation (NSF) as part of the National Science Digital Library, and is being created by a team of project partners led by Internet Scout.  http://www.amser.org/SPT--BrowseResources.php

COW is an internet utility for learning and practicing calculus. It was designed at Temple by two members of the Temple University Mathematics Department, Gerardo Mendoza and Dan Reich.  The principal purpose of COW is to provide you, the student or interested user, with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you work. This will be true no matter where you are or what computer you use, as long as it is connected to the internet and has a web browser. http://www.math.temple.edu/%7Ecow/

Many cultural designs are based on mathematical principles. This software will help students learn standards-based mathematics as they simulate the original artifacts, and develop their own creations.  http://www.rpi.edu/~eglash/csdt.html

This Online Course offers complete instruction on any/all arithmetic topics. You will be shown every concept in detail, have continuous opportunities to test your understanding, and participate in activities that identify topics that should be studied. This self-paced course is designed for teenagers/adults and the material is aimed at that level of maturity even though the concepts are completely taughthttp://www.onlinecollegeprep.com/FreeArithmetic/index.html

The Global Educational Outreach (GEO) initiative uses new technology to provide outstanding Science, Engineering and Technology (SET) teaching material. It is a highly flexible medium enabling a wide range of different educational approaches to be explored and it is particularly useful for SET teachers who will find valuable downloadable teaching resource material created by the best science and technology experts and educators. A key aim is to catalyse the creation of a global network of participating sites catering to the local and global need for much improved SET education. The material on this website is free to view and download. http://www.geoset.info/

The founders of RadicalMath believe strongly that math literacy is a civil right for all youth and that all classrooms should foster culture, unique learning styles and reflect the just societies we encourage in our own lives and teaching practices.  They ask the question of students, What are the problems that my community is facing, and how can I use math to understand and help solve them?"  Access the Guide for Integrating Issues of Social and Economic Justice into Mathematics Classrooms and Curriculum to learn about the possibilities of teaching math through a social justice lens.  http://www.radicalmath.org/

In the Internet Activities Center you will find a series of Lesson Plans with hands-on and interactive computer activities designed for young women grades 5-8 and above. The materials meet the National Science Standards while introducing basic engineering skills such as drafting, using tools, deductive skills and the scientific method. Each activity includes: grade appropriate background materials on the science or engineering subject, a list of materials, instructions for the activity, graphics (such as patterns to be cut-out, pictures or animations demonstrating the experiment or final product), the National Science Standard the activity supports, new vocabulary, and a fun interactive quiz or activity to check your knowledge of the subject. There is also a "Guide to Sharing Engineering With Girls and Young Women"  http://www.swe.org/iac/

...From elementary education to front-line research, topics span an ever-growing array of categories. Some Demonstrations can be used to enliven a classroom or visualize tough concepts, while others shed new light on cutting-edge ideas relevant to high-level workgroups and thesis research. Each is reviewed for content, clarity, and presentation, edited by experts at Wolfram Research to ensure quality and reliability. http://demonstrations.wolfram.com/
