SYLLABUS/ CLASS CONTRACT

Class Code: MGS22 Subject: Geometry Common Core Term: Fall 2017 Teacher: Mrs. Montoya

Email: Phone (718) 937-6005 Ext 315

Website: Office: 315

  1. Course goals & objectives

Geometry is intended to be the second course in mathematics for high school students and it is given in two semesters. The primary goal of this course is to understand geometry from different viewpoints, both classical and modern; as well as to provide the student with the requisite foundation for the study of advanced algebra and trigonometry. Another goal of this course is to help the student becomes adept at mathematical communication. Opportunities to improve their communication skills on several levels will arise throughout the course: speaking precisely about mathematical ideas in class; writing formally and informally about mathematical ideas and learning how to write concise but complete arguments.

2. Suggested Materials

  • Notebook or Binder with Notebook Paper (College Ruled) and graph paper preferably.
  • Pencil/Pens (black or blue ink only), eraser, sharpener.
  • Set of Rulers and compass
  • Calculator (Preferably scientific, but does not need to be a graphing calculator)

3.Course Requirements & Expectations

·Lateness & Absences

All students are expected to arrive in class before the bell rings, however if a student is late to class he or she must bring a pass from a teacher or school official, and must sign the lateness log. Excessive lateness or cutting will result inparent contact as per the school’s discipline policy.

Bring an absence note when you return to school. Any student who is absent is responsible for obtaining the class notes, making up assignments, quizzes, or tests, and learning the material that was missed.

·Binder’s sections:

1-Notes with hand outs (Aim #, Do Now, Examples, and Practice);

2-Homework,

3. Quizzes, Exams, and extra credit;

Your Binder will be checked each marking period.

·Behavior

Students are expected to behave appropriately during class. Talking, calling out, use of cell phones, and other inappropriate behavior or disruptions will not be tolerated. Any behavioral infractions will be addressed as per the school’s discipline policy.

·Homework:

Homework will be given, revised and evaluated on weekly basis . Make sure you write your name, date and show all your work, not only final answers. Assignments will be graded for effort. Work needs to be shown for each problem to receive credit. Some HW assignments will require the use of the school’s website below. The school provides access to the internet at the library.

·Exams and Quizzes

You will have an exam every two weeks during the semester. There will be no make-up exams unless you bring a formal excuse. If you are absent and do not bring a written excuse, you will receive a grade of zero which can have a great impact on your final grade. Cheating will not be tolerated. Cheating will result in a zero grade.

·Class participation

Students will receive extra credit for full participation if they are on time, have all their supplies for class, and demonstrate on-task behavior. Students who attend the geometry after school and peer tutoring will receive extra credits.

·Bathroom/Hallway Pass

The pass will never be given out the first and last 10 minutes of the period and use the bathroom log to record the time you are out. Also, it is extremely important to be in class paying attention while I introduce the topic. I strongly recommend limiting the use of the pass in case of emergency only.

4. Themes & Topics

. The study of Geometry includes math vocabulary, organization of proofs, points, lines, planes and angles, parallel lines and planes, transformations and congruence, congruent triangles, similar polygons, right triangles, circles, areas of plane and solid figures, volumes and surface areas of solids, using formulas in solving problems, visualizing geometric situations, and using geometric ideas in real situations.

5.Assessment Policy for each marking period

  • Homework (20%)
  • Exams/Quizzes (50%)
  • Notebooks/Class Participation (20%)
  • Projects (10%)

The final grade for this class is an average of first, second and third marking period grades.

The passing of the Regents Exam could affect your final grade to a maximum of 33%).

( Only classes ending with a Regents).

6.Contact Information

  • Parent-Teacher Conferences: For the Fall2017 semester: Thursday, November 9, 2017 (6:00-8:30 PM); and Friday, November 10, 2017 (1:00-3:10 PM).
