TITLE: GSP Introduction
In this lesson, students will be introduced to GSP.† They will be learning how to make points, segments, lines, and rays.† They will also make angles.
After this lesson, the students will have a better understanding of the basic functions of GSP.† They will also be able to draw a point, segment, line, ray, and angle and differentiate between them.
Identifies and distinguishes among points, lines, line segments, rays, and angles.
Review the terms point, segment, line, ray, and angle.
Using GSP, students will draw a point using the point tool.† They will make a text box and define a point.† A point is defined as any point in space.
Next, the student will draw a line segment using two points and connecting them as a segment.† They will make a text box and define a segment as a line with two endpoints.
The student† will draw a line using the construct tool.† They will define it in a text box as a line in space that goes on forever in both directions.
The student will draw a ray using the construct tool.† They will define it as a line with an endpoint that goes on forever in one direction.
The student will draw an angle by constructing two rays with a common endpoint, called a vertex.† They will define an angle as two rays that meet at a common endpoint.
This lesson will be assessed by the studentsí drawings and definitions.
Students will draw an acute, right, and obtuse angle and prove the measures.
This concept can be taught differently by finding real-world examples and then comparing them to the GSP sketches.
