Interactive Mathematics Miscellany and Puzzles

This site is for teachers, parents and students who seek engaging mathematics. Many of the topics are accompanied by Java illustrations. There are more than 900 Java applets. The applets can be licensed by teachers for inclusion in their own pages.

Most recently I have moved the greatest part of the Games and Puzzles section to a separate site CTK Math Games for Kids. This allowed me to switch from the older applet tags to the object tags that are fast becoming common nowadays. This will insure that the applets always run in the most appropriate version of the Java Virtual Machine without the need for my or user intervention.

The applets run in a browser Java addon and also need a few smaller libraries. For this reason, pages that carry applets may take longer to load than the Java free ones. However, the libraries have to be loaded only once: subsequent pages load pretty fast. Also please note that the Microsoft's Internet Explorer (IE) comes with its own Java Virtual Machine (JVM), the software piece which executes Java applets. The Microsoft's implementation of JVM is inferior to the Sun's and lacks certain features needed by some applets. It is recommended for the IE users to upgrade the JVM, which can be done by downloading it from the Sun's site. The installation procedure is virtually automatic.
