The Open University had long been dedicated to the proposition of providing high-quality educational materials for persons all over Britain and the world. They were one of the first universities to place such materials online, and their OpenLearn website has received high marks from many quarters. This particular section of materials on their site is devoted to providing instructional units in both math and science. Currently, the site contains about 30 different units, and visitors can stroll through these units and take in their materials at their leisure. The units include such titles as "Modeling pollution in the Great Lakes", "Exploring data: graphs and numerical summaries", and "Using vectors to model".

The Calculus Page

http://www.math.ucdavis.edu/ ~calculus/

From time to time over the past several centuries, the word "calculus" has caused more than a few college students to break out into a sweat and become a bit anxious. These potentially embarrassing moments can be alleviated by a visit to The Calculus Page. The site is under the direction of Professors Joel Hass and Duane Kouba, and it features dozens of links to valuable online resources that deal with this branch of mathematical inquiry and discovery. The first section of the site is dedicated to providing materials for students of calculus (including calculus animations and sample exams) and a number of resources for instructors follow. The site is rounded out by links to other relevant websites and online portals, so interested parties will definitely want to make several return visits.

Quantitative Literacy

http://www.beyondcrossroads .com/QLindex.html

Quantitative literacy is rather important, and for teachers working in different areas of the mathematical sciences, it can be of the utmost importance. Working with different schools of the Beyond Crossroads consortium, this website provides a number of helpful resources on this important subject. The site is divided into areas that include "What is Quantitative Literacy?" and "Quantitative Literacy Websites". In the first area, visitors can view video clips of different experts talking about the nature of quantitative literacy and its applications in a number of educational settings, including community colleges. After looking at some of these clips, visitors will want to look at the "Books and Articles on Quantitative Literacy" area, which includes information about high-quality print and online resources that address this topic.

Fun Mathematics Lessons

http://math.rice.edu/%7Elanius /Lessons/

To the unconverted, the words "fun" and "mathematics" might not seem to be words that should be that close together in any one sentence or phrase. Educator and mathematics guru Cynthia Lanius proves any potential naysayers wrong as she offers up over two dozen interesting and engaging math exercises for educators to use in their classrooms on this site. She's served as a consultant for the Math Forum@Drexel and other educational websites, and her work here includes some great examples of sound educational pedagogy. While some of the activities are geared towards young children, some of the activities (such as "Mathematics of Cartography" and "Online Geometry") will work well with older students who might be enrolled in a developmental math course at the high school or community college level. One other nice feature of this site is that some of the activities are also available in Spanish.

U.S. Treasury: Office of Financial Education

The people at the U.S. Treasury's Office of Financial Education know a bit about interest rates, mortgages, and other related matter, so it's good to learn that they have developed a good set of educational resources designed for teachers. The site includes materials developed by organizations within the U.S. Treasury, including the Federal Deposit Insurance Corporation, the Federal Reserve Bank of Dallas, and others. The materials here include "Money Smart", which is a curriculum designed to help adults understand basic financial services and "Building Wealth", which presents an overview of such important strategies as creating a household budget and managing debt. These various tools could potentially be used in applied economics and mathematics courses , and teachers will appreciate the flexibility of these different resources.

Interactive Mathematics Miscellany and Puzzles

http://www.cut-the-knot.org /content.shtml

Created by Alexander Bogomolny, this site is a clearinghouse of fun and engaging mathematics exercises, puzzles, and other such activities that teachers can utilize in their classrooms. Of course, students might happen across the site and they might become math converts along the way. First-time visitors might wish to read Bogomolny's "manifesto" for the site, and then they can dive right into the material offered here. The offerings are divided into a number of sections, including "Visual Illusions", "Algebra", and "Probability". One particularly nice feature of the site is that many of the exercises and activities here are accompanied by helpful Java applets that include charts, graphs, and other such dynamic elements. Finally, visitors shouldn't leave without visiting the "Mathematical Droodles" section as it's both engaging and thought-provoking.

xyAlgebra

http://www.xyalgebra.org/

For students in college-level math courses, revisiting algebra can be a challenge, and learning for it the first time can prove to be tricky as well. This website, created by Professor John Miller of the City College of the City University of New York (CUNY) contains a very helpful tutorial application that can help students master different aspects of algebra. This application features explanations of 320 different aspects of algebra, step-by-step sample problems, and even hints to help students along their way. Visitors will also appreciate the fact that the website contains several demos and a set of resources for instructors

The Josephus Problem

http://mathdl.maa.org/mathDL/3 /?pa=content&sa=viewDocument &nodeId=322

Flavius Josephus was a Jewish historian living in the first century when he and his comrades found themselves trapped in a cave. Surrounded by Roman centurions, this band chose suicide over capture, and they elected to form a circle and then start killing themselves. From this rather traumatic situation came the well-known Josephus Problem, a classic problem of recreational mathematics. This educational resource offered by Doug Ensley of Shippensburg University will help math teachers teach their charges about this fabled problem. This site includes an interactive demonstration of the problem, complete with a historical background essay. Additionally, the site also contains information about making the best use of this resource in the classroom.
