on the Web
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
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.
Computers with Internet access are required. Certain lessons include
activities using the T1 graphing calculator.
These lessons apply to students from eighth grade to twelfth grade,
but they are most appropriate for the tenth grade.
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.
Make sure the Internet sites are working before taking students
to the computer lab.
