Sci-Ed This is a searchable database for subject area resources. This is the most user friendly ftp site I have found. Read the directions carefully and you will be very happy with this rich resource. It is a large collection of resources in many areas. In each directory you are supplied with an annotated index of the files available and the program you need to uncompress them if you need it.
Resources range from many utilities to educational resources to business applications an d more.
There are programs for a wide range of mathematics topics. There are tutorials in algebra and statistics, statistics packages, graphing utilities, and a mathematics problems generator. This is a site every mathematics teacher will want to visit often. This site houses many resources for the mathematics teacher and student using Logo.
