Course Description

Geometry is the study of points, lines, angles, shapes, surfaces, and solids. Topics include planes, triangles, polygons, parallelism, congruency, similarity, triangle inequalities, trigonometry, circles, area and volume, coordinate geometry, symmetry, and transformations. Theorems and other results are derived using formal reasoning. Mathematical ideas are communicated using graphical (drawings, graphs, sketches, geometric constructions), numerical (tables, patterns, calculations), algebraic (formulas, symbolic reasoning, solutions), and verbal approaches (conjectures, proofs, explanations, self-reflection). Applications and hands-on activities are integral parts of the course.

Text and supplemental materials


Homework: timely completion of homework assignments. Assessed formally and informally. 5 points per homework
Quizzes and Tests: written and graphical solutions. 50 points per quiz, 100 points per test
End-Semester Examinations: written and graphical solutions of problems from the whole semester (comprehensive). 15% of course grade

In-Class work and Projects: positive energy and interest level during in-class work including discussion, working on investigations and projects, practice during class, and using notes. Assessed informally.

20 points per week, up to 100 points per project
Note-taking: documenting work (including graphical, numerical, algebraic, and verbal work), putting notes to good use for learning, making the note-taking process your own, and showing the ups and downs of the learning process. Assessed informally. included in in-class work
Commitment to learning: Taking on what is challenging to you, getting help, communicating with the teacher, engaging with the material, and taking personally meaningful notes. Assessed informally. 100 points per semester

Safety policy: only use equipment when and as instructed

Late work policy and tardy policy

The teacher enters grades once per week on Fridays. Students get credit for late or partial work up to that weekly deadline. Students who are tardy to class or leave the classroom for an extended time during class receive a maximum of 60% of the day's in-class work credit.

Cell phone and device policy

Devices are not allowed in class, except by explicit permission to do class work. If you need a calculator, please go borrow a classroom calculator or ask the teacher as soon as possible.

Class computer use policy

Personal and school computers shall be used for this subject only. The Marin School supports the responsible use of technology on our campus. See the Parent and Student Handbook.

Collaboration policy

I encourage study groups. You may work with others (not just students) unless instructed otherwise as long as all of you contribute. It is wise to put the name of each contributing student on an assignment to avoid issues with plagiarism.
