Although it is presented as a collection of lecture notes on numerical analysis, this is essentially a full-fledged online book on the topic. Written by a professor of mathematics at Pennsylvania State University, the 125-page document spans three chapters and covers various forms of differential and difference equations, methods for solving them, and linear algebra. Scattered throughout the text...

Offered by Cleveland State University's Department of Electrical and Computer Engineering, these five virtual experiments "are intended to broaden and deepen a student's understanding of linear systems concepts by allowing interactive exploration of various issues." The experiments start by introducing a certain situation and giving necessary background to understand the properties of the...

This British website developed by Earl Fife or Larry Husch provides a database of information on Applied Mathematics. Visitors can search by keyword or scroll through by topics, such as History of Mathematics, Industrial Mathematics, Linear & Nonlinear Programming, Multivariable Calculus, or Ordinary Differential Equations among others.

Mathematical BBS, which began in 1993, is managed by a team of academics at the University of Ferrara. From this portal site, visitors can find links to associations, departments, commercial organizations, journals, and personal homepages relating to various topics in mathematics. The links are organized by topic and then by resource type and discipline. Some topics include bioinformatics, medical...

It is at times very difficult to get children excited about math, but Math Cats (designed by Wendy Patti, a teacher) is an online archive of fun and informative activities that will help young people learn about a number of math topics, including geometry, arithmetic, and other topics. As one might expect, much of this is achieved by a number of virtual cats who explain various features of the...

Designed for mathematics educators, the Math Ed Podcast features conversations with experts across the globe about a wide variety of issues relating to mathematics instruction and the latest research in the field. This podcast was founded in 2012 by Samuel Otten, assistant professor of mathematics education at the University of Missouri. One recent episode features a conversation with Mandy Jensen...

There are many learned (and not-so learned) professions that get a bad rap in the world of cinema. Scientists, and mathematicians in particular, tend to be portrayed alternately as either evil madmen or troubled geniuses. Through this website, Arnold Reinhold offers his informed and honest appraisals of mathematicians (and their math, of course) in various films. To get a sense of the project,...

The Math Projects Journal (MPJ) is "dedicated to improving mathematics education by empowering teachers with lessons and ideas" based on "four and a half" principles which are described on the website. This website offers a selection of free lesson plans and articles on pre-algebra, algebra, and geometry. A 300-page spiral bound book of lessons and articles published in the first five years of MPJ...

Math-Kitecture, designed by Charles Bender, "is about using Architecture to do Math (and vice versa)." The author provides suggested activities that engage students in doing real-life architecture while learning estimation, measuring skills, proportion, and ratios. The main activity is for students to hand-draft a floor plan of their classroom to scale and then use software to create a...

Professor of Mathematics Scott W. Williams has created this website dedicated to the ancient and modern achievements of the peoples of Africa and the African Diaspora within the Mathematical Sciences. One of the purposes of this website is to disprove proclamations by some that "The Negro is incapable of succeeding." Some examples of such false statements are provided along with a longer list of...
