Geometry (M310b) 2008-2009
Instructor: Karl Erickson
Textbook: A Course in Geometry, Weeks and Adkins, Bates Publishing, 1982
Course description: Geometry is a system of study of size, shape, and position of figures where a few simple statements were assumed, and then used to derive more complex ones through the process of deductive reasoning. Geometry is a useful, logical, and challenging study, which will give meaning to many abstract concepts found in algebra. We will work with the deductive proofs, geometric shapes, traditional constructions, and coordinate systems. While we will use the textbook for exercises, we will be covering much of the material in class lessons, so it is important that you attend every class and pay close attention.
Materials/Technology:
For this course, you will need a TI-83/83+/84 calculator, a geometry “pack” which includes a compass, ruler, and protractor, a notebook or 3-ring binder, and either loose lined paper or an engineering pad to turn in homework Most importantly, bring a curiosity and open mind and this will make the course much more enjoyable for all of us.
Homework:
Do the homework! Tests and quizzes are based on problems similar to those assigned in the homework. Your grade on your homework is primarily an effort grade: if you show your work and demonstrate that you have made a good effort on all of the problems, you can earn full homework credit.
Grading:
Your grade will be determined by your performance on Tests, Quizzes, Homework, and Projects, with the median grade being in the range of B/B+. This means that while we can approximate your grade throughout the term, you won’t know your exact final grade until the end of the grading period. All of your points will be added to determine your grade, so remember: a point is a point, whether it is from homework, a test, or an assignment.
Attendance:
Attendance at every class is mandatory. If you know you will be missing class, see me ahead of time. If you are absent, you need to make up the work as soon as possible. If you are just going to miss your math period for some reason, you are more than welcome to attend any of the sections of Geometry taught by myself, Mr. Platt, Ms. Gallagher, or Mr. Garnevicus. It is probably easiest to contact me by email if you have any questions.
If you need any help with the material, please see me as soon as possible. Your success is dependent on both of our efforts.
