Courseware is software or organized content that can be used in the preparation or teaching of a course. This section contains links to web-based courseware resources. Downloadable courseware is listed on our Software page.
CCNYMath.net is a Flash-based set of instructional web pages written and designed by Stanley Ocken, Professor of Mathematics at City College, and the late Jack Schwartz, a former CCNY math graduate and Professor Emeritus of Mathematics and Computer Science at New York University. You may contact Professor Ocken with any questions or suggestions for the site. You will need to have a Flash plug-in installed in your web browser to use this site.
Baruch College’s Student Academic Consulting Center links to sample handouts and exams for some of Baruch’s math classes, as well as math tutorial videos in Baruch’s Digital Media Library. Video tutorials include college algebra, precalculus, and calculus. You must have a web browser with a plugin capable of playing QuickTime movies to view these videos.
Calculus+ is a series of tutorials in precalculus, calculus, linear algebra, and differential equations, using Maple 8 or higher. These projects were developed by CUNY faculty and tested in CUNY classrooms from 1998-2004.
Problems and Puzzles

Project Euler is a collection of mathematics and computer science problems that require a combination of mathematical insight and programming skills to solve. They are primarily numerical in nature.
In Nick’s Mathematical Puzzles, Nick Hobson, a worker in computer software with a mathematics background, has collected over 150 mathematical puzzles of varying difficulty.
Math Q&A and Learning Tools
Ask Dr. Math, at Drexel University’s Math Forum, is a question and answer service for math students and teachers. You can search their archives on multiple knowledge levels, or ask a question to the forum yourself. Drexel also hosts a site of links called the Internet Mathematics Library.
At Interactive Mathematics Miscellany and Puzzles, Alex Bogomolny indexes over a hundred Java-based mathematics and puzzle applets.
Wolfram|Alpha, the Wolfram “computational knowledge engine”, calculates answers to various questions using Mathematica packages and data from multiple online sources.
Math Overflow is a “place for mathematicians to ask and answer questions.” The primary criterion for determining whether a question is appropriate for Math Overflow is, “is this of interest to mathematicians?”
The Tricki, a “a repository of mathematical know-how,” is a wiki which seeks to codify methods of mathematical technique and problem-solving.
The ProofWiki is “the online compendium of mathematical proofs.”
MathIM allows anyone to chat online using LaTeX expressions.
