Javasketchpad

Please send comments to Mr. W.K. Cheng.


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 brower.

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.
