ELET 5100 - Visual Literacy Through Digital Investigations
CONSTRUCTIONS LEARNING MODULE
Lesson Topic: Geometry – In this module, students will be able to perform basic constructions with a straight edge and
compass. The students will then apply their knowledge of basic constructions to produce other constructible objects.
Learning Outcomes:
1. Describe the instruments in basic constructions, and how they are used.
2. Perform the basic construction of copying a line segment.
3. Justify why each step in the basic construction of copying a line segment is needed for producing the desired
outcome.
4. Identify the constructions needed to produce parallel lines through the use of geometric dynamic software,
Geogebra.
5. Create constructible objects using the 4 basic constructions.
Identify the target audience: This module will target students of Liberty North High School enrolled in my Geometry
class. In this class, the male and female students range from freshmen to juniors, which range in ages from 14 to 17.
Many different ability levels and ethnic backgrounds are represented in all of my Geometry classes.

Outcome:
2. Describe the instruments in
basic constructions, and
how they are used.
In this podcast, learners will listen to a
quick history of constructions. Finally,
They will be introduced to the two
instruments necessary for completing
constructions.

4. Identify the constructions
needed to produce parallel
lines through the use of
geometric dynamic
software, Geogebra.
In this presentation/screencast,
learners will explore how to use
constructions to create parallel lines in
geometric dynamic software called
Geogebra.
Presentation Script:
“Welcome to Mr. Armstrong’s
Geometry Podcast. Glad to have you
listening today as we dive into the
awesome world of “Geometric
Constructions”. By the end of this
podcast you will have knowledge of
the history of geometric
constructions. You will also possess
the knowledge about the use of each
tool used in geometric constructions.
Shall we begin?...”
video in a series of 4 about basic
constructions. This video is going to
focus in on how we use a compass
and straightedge discussed in our
podcast to copying a line segment. If
you get lost at any time during the
video, just stop and back up the
scrolling time bar below. Now, for
this construction you will need the
following materials:
 Piece of Paper
 Pencil or Pen (Better to use
pencil in case you make a
mistake.)
 Safety Compass
 Ruler
Now, let’s get ready…”

geometric constructions that we have
learned in creating parallel lines.
You will see that this presentation is
comprised of two different sections.
The first section is basic tutorials
using the dynamic geometric
software Geogebra, and in it to
contains the tutorials of all the
different functions that you will have
to use when creating parallel lines.
The second section is the actual

Outcome:
5. Create constructible objects
using the 4 basic
constructions.
In this interactive instructional quiz,
learners will be assessed on how well
they analyze an object and how the 4
basic constructions can be used to
create new objects. They will also
review materials taught throughout
the learning module
Interactive Activity - Quiz Questions
through adobe flash:
1. What constructions are used to
create a 45-degree angle?
2. Why is it important that the
same arc is used when copying
from the original segment to the
new drawn point?
