**TITLE: GSP Introduction**

* *

**Annotation**

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.

## Primary Learning Outcome:

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.

**Assessed QCC:**

Identifies and distinguishes
among points, lines, line segments, rays, and angles.

**Total Duration:**

*50 minutes*

## Materials and Equipment:

## Technology Connection:

*Geometer’s Sketchpad*

**Procedures:**

__Step One__

Review the terms point, segment, line, ray, and
angle.

**Estimated Time**:

10 min.

###### Step 2

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.

**Estimated
Time:**

5
min.

###### Step 3

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.

**Estimated
Time:**

5
min.

###### Step 4

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.

**Estimated
Time:**

5
min.

###### Step 5

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.

**Estimated
Time:**

5
min.

###### Step 6

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.

**Estimated
Time:**

5
min.

**Assessment:**

This lesson will be assessed by
the students’ drawings and definitions.

Extension:

Students
will draw an acute, right, and obtuse angle and prove the measures.

Remediation:

This concept can be taught differently by finding
real-world examples and then comparing them to the GSP sketches.
