Interactive Math Applications

This is a summary of the various interactive graphs, calculators and other manipulatives here on IntMath, and on the squareCircleZ math blog.

If you use the Interactive Whiteboard in your math class, this is an ideal place to start!

These interactives work on all browsers except where indicated. Many of them work on mobile devices, but not all (this is also indicated against each app).

The order of the topics is similar to the order followed by IntMath.

The various manipulatives that are linked on this page were created using javascript, Java, Flash and LiveMath. You can read more about these at the bottom of the page.

The icons below each link indicate the technology behind each manipulative.

Software Used to Create the Interactives

JSXGraph Interactive Graphs

JSXGraph is a great way to interact with math concepts. You can view the graphs and interact with them on most computing devices. JSXGraph does not produce image files as it is based on javascript. Compatability:

• Works on Windows, Mac and Linux
• Works in all browsers (Chrome, Firefox, Safari, Opera and IE)
• Works on some mobile devices (iPhone, iPad, Android)

SVG Graphs

SVG stands for "Scalable Vector Graphics" and is the favorite format for graphic artists. You can see graphs on a Web page without using image files, similar to JSXGraph.

Compatability:

• Works on Windows, Mac, Linux
• Works natively on Chrome, Firefox, Safari (IE needs a plugin)
• Generally does not work on mobile devices

Flash

Flash is a versatile development platform that was available on most platforms. But since it is a proprietry system (owned by Adobe) and is a power drain on mobile devices, most smartphones and tablets do not support Flash applets.

Java

Java is also a cross-platform, cross-browser platform which works fine on desktops and notebook computers. However, most mobile devices do not support Java.

LiveMath

LiveMath is a cross-platform and cross-browser interactive math application. Unfortunately, the browser-based plugin became very unstable as the Web developed, but it still has some good applications.

It seems that LiveMath is no longer under development, so I've been slowly replacing each of the interactives whenever I can.
