Javasketchpad is a very useful tool for both teaching and learning. Diagrams drawn by the dynamic geometry software Sketchpad could be converted to Javasketchpad diagrams. Teachers and students could access these diagrams through the Internet easily without the software Sketchpad. The only thing needed is a Java-capable browser.

The following are diagrams specially designed for Mathematics teaching and learning. The first time you load one of these pages will take you about one to two minutes, but then the next time will take you less than 30 seconds. Therefore be patient during the first time.


If you would like to download any file from this page, please feel free to do so, but note the following points.

1. You should use the files for non-commerical purpose only.

2. You can modify the contents inside or add Chinese as text and then use them for off-line browsing. However, please don't post it in the internet as your own web pages.
