Integration of Geometer's Sketchpad in the Intermediate Division for Ontario Schools


Introduction

Math is a complex subject not only to learn, but also to teach.  It is essential for educators to utilize as many different tools and strategies as possible.  One useful instrument to aid in teaching intermediate mathematics is the computer.  In particular, Geometer’s Sketchpad.  Geometer’s Sketchpad is a computer application designed to integrate mathematics with technology to produce visual representations of math created by the students.  This compilation of lessons for grades seven and eight will aid intermediate educators in teaching the mathematics unit, Geometry and Spatial Sense.  Each lesson is specifically tailored to meet the Ontario Curriculum guidelines.  The specific and overall expectations for grades seven and eight will be sufficiently met throughout the various chapters in this GSP package. 

The different geometric concepts that are investigated in this compilation include: Points, Lines and Angles, Triangles, Ratio and Proportion, Transformations, Symmetry, Area, and Volume.  Along with mathematical terminology and concepts, students will gain a solid understanding of the various commands and functions within the Geometer's Sketchpad program. 

Prior to examining each lesson, it is imperative to note that educators may use both teacher-direct and student-direct approaches to using Geometer's Sketchpad.  However, it is recommended that educators guide students through the first couple of lessons in each chapter to perform diagnostic testing of the material and the recollection of Geometer's Sketchpad commands previously taught.  This will help educators determine the level students are performing at.

NOTE: A basic understanding of the mathematical terminology and concepts prior to using Geometer's Sketchpad is essential in order to properly follow and understand the commands used in the program.
