Mathematics
 The Interactive Library is about "real interactivity"! The database contains hundreds of activities that make use of sophisticated java, vrml and shockwave prgrams. If you are unfamiliar with java or shockwave take a look at these sample programs. -Teachers Create your own activity sheet to go with the prgrams and your students are set for a new experience. -Students Use these programs to supplement your classroom activities, or use one of the more advanced applets as a starting point for your science project. -Parents Use these programs to supplement your childs homework.
