Introduction to Geometry

Where to Get Help
326 Walker Hall,
I am always happy to help you in office hours. An open door
means that I am on the floor somewhere, so come look for me.
Check the main web page often for homework and for access to the other
is the easiest way to ask a math question outside of class and office hours.
You are responsible for reading all posts from me. I prefer that you use office hours since it is easier to discuss material in person, but if you can not make them, then it is a great alternative. I usually check it
every day including the weekends.

access to a web-browser
3-ring binder notebook and a hole puncher to
organize handouts, notes and your work
printouts of your work
manipulatives required to complete projects
access to the software package Geometer's Sketchpad (GSP), which is
available in some computer labs on campus. If you have time to work
on campus, this suffices. Otherwise you may want to purchase a copy
pricing is a 1-year license for $9.95 and a non-expiring license
Course Goals and Objectives
A study of the development of Euclidean geometry through multiple
perspectives, including synthetic and metric. Topics to be considered include
parallelism, similarity, measurement, constructions, an axiomatic
approach to polyhedra, and at least one non-Euclidean geometry. The course
will focus on concept development and connections among mathematical
perspectives. (SPEAKING) Prerequisite: MAT 1120
In order to foster concept development and connections among multiple
perspectives, we will examine
the foundations of geometry through the lenses of
mathematical reasoning and proofs, manipulatives, dynamic geometry
software, and the historical progression of geometry.
We will also develop problem solving and visualization skills and express
geometric concepts in a variety of formats.
has been designated as a
course. In order to satisfy the speaking designator, presentations
will occur during the semester and during a final project.
This is a mathematics content course, which means that it will
stimulate the intellectual growth of each student.
While many of you are future teachers and
some of the mathematics covered in the course will be related in
meaningful ways to materials that can be taken into the classroom
(for example, various ways of teaching and learning geometry will
be modeled), the primary purpose of this course is your mathematical
Participation in Classroom Activities 20%
You are expected to contribute to discussions in a meaningful way and actively engage the material in class and lab. You must be prepared for each class and check the main web page regularly for hw. Attendance is required.
These kinds of baseline activities will result in a participation grade of
16/20. Other activities can increase or decrease this grade.
Utilizing office hours and ASULearn,
asking and answering thought provoking questions, coming up with creative ways of thinking about the material, and explaining the material to others are some examples of positive participation that will increase your grade. On the other hand, performing activities that detract from the professional classroom environment or distract Dr. Sarah (who is very easily distracted) will result in a lowered participation grade.
Many activities and class discussions are designed to be completed during class. Thus, attendance is required at ALL classes, and will form a portion of your grade.
Missing more than the equivalent of 2 weeks during the semester (4 class
days) will result in an automatic F in the course. Save your
absences for emergencies. If the university is open and you miss a class, then that counts as an absence. If you must be late to a class, or must leave early, then do still attend.
Work will not be accepted without explanation and must also be turned in on
or before the due date.
May occur during the last week of classes.
If there is some reason you must miss a class, then
obtain the assignment from the web pages. The lowest project will be
dropped - save this for emergencies. Every other project will be equally
weighted regardless of the total number of points.
If all of your
projects are turned in on time AND you have received at least a grade of
75% for all work, then you will receive an on-time credit of +1
added on to your final average. No lates allowed*.
Tests may be oral, written or on ASULearn.
Tests are not only an opportunity for you to demonstrate your mastery of the material, but are also an opportunity for you to be challenged
with new material in order for you to make new connections.
No make-ups allowed*. May occur the last week of classes.
Final Project Presentations 15% No make-ups allowed*
*Work may occur during the last week of classes. Accommodations in the determination of your final grade will be made for extenuating circumstances that are documented to prevent you from
completing work early/on time.
Except in extraordinary circumstances,
for religious observances required by faith must be submitted
in writing no later than three weeks after the first class day of the
Appalachian State University is committed to making reasonable
accommodations for individuals with documented qualifying disabilities
in accordance with the Americans with Disabilities Act of 1990, and
Section 504 of the Rehabilitation Act of 1973. Those seeking
accommodations based on a substantially limiting disability must contact
and register with
The Office of Disability
Services (ODS) 828-262-3056. Once registration is
complete, individuals will meet with ODS staff to discuss eligibility
and appropriate accommodations.
When writing up work, be sure to give acknowledgment where it is due. Submitting someone else's work as your own (PLAGIARISM) is a serious violation of the
University's Academic Integrity Code.
We adhere to the code in this course.
Other Policies and Methodology
Plan to spend at least 1-2 hours outside of class for each credit hour in class, (on average).
You are responsible for all material covered and all announcements
and assignments made at each class, whether
you are present or not. You are also responsible for announcements
made on the web pages, so check them often.
Asking questions, and explaining things to others, in or out of class,
is one of the best ways to improve your understanding of the material.
This course is to be an environment in which everyone
feels comfortable asking questions,
making mistakes, offering good guesses and ideas, and is respectful to
Turn in projects or prepare to present problems
even if it they are not complete, even if only to say, "I do not
understand such and such" or "I am stuck here."
Be as specific as possible.
When writing up work, be sure to give acknowledgment where it is due.
Submitting someone else's work as your own (PLAGIARISM) is a serious
violation of the University's Academic Integrity Code.
In this course, you will be challenged with problems that you have never
seen before. I do not expect you to be able to solve all the issues
immediately. Instead, I want to see what you can do on your own.
Out in the real world, this is important, since no matter what job
you have, you will be expected to seek out information and answers
to new topics you have not seen before.
This may feel uncomfortable and frustrating. I understand this
and want to help you through the process.
It helps to remember that
there are no mathematical dead-ends!
Each time we get stuck, it teaches us
something about the problem we are working on, and leads us to a
deeper understanding of the mathematics.
In the real world though, you are not expected to face your work alone.
In this class, you are also not expected to face your work alone.
I am always happy to help you in class, during office hours (or by
appointment), or on ASULearn, and will
try to give you hints and direction.
At times though, to encourage the exploration process,
I may direct you to rethink a problem
and to come back to discuss it with me again afterwards. This occurs
when I believe that the struggle to understand is imperative for your
deep understanding of the material.
