Geometry on the Web

Project URL:

How it works:
Geometry on the Web is a conglomeration of instructive Internet sites on the basics of geometry. Students explore various sites that coincide and correspond with their classroom lessons and topics. This resource was developed to assist students in preparing for their New York State Math A Regents Examination, but can certainly be adapted to any curriculum in which these topics are covered.

Standards addressed:  
This program addresses the basics of geometry: points, lines, planes, area, perimeter, measurement, triangles, polygons, parallel lines, quadrilaterals, slopes, the Pythagorean theorem, trigonometry, transformations, and the coordinate plane.

Materials used: 
Computers with Internet access are required. Certain lessons include activities using the T1 graphing calculator.

The students:
These lessons apply to students from eighth grade to twelfth grade, but they are most appropriate for the tenth grade.

Overall value:
These are great lessons for adding flair and interest to the regular mathematics class. Many sites have interactive lessons and activities, and students get an immediate response. It provides an additional way to understand or learn a geometric topic. The graphics and visuals are an effective means of communicating various concepts.

Tips: 
Make sure the Internet sites are working before taking students to the computer lab.
