Abstract
The technology is a compass and ruler with pencil and paper. The scope of this mathematics section is to develop step by step construction with visual hands-on skills which I have been teaching since 1992. Drawing accurate diagrams as demonstrations of geometry instruction is an essential goal. Starting the lesson, students practice the use of the compass and ruler to build geometric figures. The lesson is designed to represent the square root of a number on a number line and locate precisely. We are going to learn the steps for representation of irrational numbers on a number line and solve a few examples to understand the concept better. In terms of a visual representation we are going to use a horizontal number line. One must understand the definition of irrational numbers a history of irrational numbers. Irrational numbers have decimals that neither terminate nor become periodic.
