Introduction & Welcome
Welcome to Geometry! I am looking forward working with
you and hope that your year is both fun and challenging.
This handbook contains almost everything you need to
know about this class and my expectations. Please keep
it with your math notebook at all times so that you can
review classroom information regularly.
Geometry is one of the most useful and relevant math
courses you will take in high school. We are surrounded
by geometric ideas every day. Through the study of lines,
polygons, circles, and solids, you will learn to apply
geometry to your world. Though you will not be asked to
draw on your Algebra skills every day, the ability to solve
simple equations is expected regularly. Please ask for
help if this is a weakness for you.

Graduation Requirements
End of Course Assessment (EOC)
Students are required to pass one state assessment in order to graduate (Algebra EOC, Geometry
EOC, or SBAC). If you did not pass the Algebra EOC, then you will be offered intervention this fall
and a retest in January. The Geometry EOC will be given in late May or early June. Geometry
students who passed the Algebra EOC will not be required to test. A passing score on an EOC will
grant course credit, but is not sufficient for advancement to the next level.
High School Math Credit
BHHS students are required to earn 3 full years of math to graduate. This most likely includes
Algebra 1, Geometry, and Algebra 2. Financial Literacy may replace Algebra 2 if taken in the senior
year.
Four-Year College Entrance
Four year colleges and universities in Washington State require completion of Algebra 2 for
entrance. Taking 4 full years of math, however, will improve your chances of college acceptance at
competitive institutions.
General Classroom responsibilities
Be Here and Be Prompt
Please take responsibility and be here, on time, every day. Absences in math class are the number
one reason students struggle. Class begins at the bell.
Be Prepared
Have required materials with you every day. .
Be Willing to Try
By completing your assigned practice every day, you will learn Geometry quickly and will minimize
the need for extra help. If you get behind, get help immediately.
Be Honest
You have a right to get credit for your own work. Please do not share your papers with other
students so that they can copy what you spent your valuable time doing. If a friend asks you if
he/she can copy your paper, try this:
“I can’t let you copy my paper, but I’d be happy to help you with your assignment.” 
Be Helpful
We’re in this together. Please be willing to help those around you when necessary and appropriate.
Be Neat
According to school policy, food and drink are not allowed in the classrooms or pods of the B
building. In this room, I allow drinks with lids only.
 PLEASE …. pick up after yourself before leaving class.
BHHS Geometry 2013-14
Page - 3 -
Be Respectful
Cell phones and portable listening devices must be out of sight and
sound at all times unless permission is given by the teacher. Please
check your texts and other messages during passing time or lunch. If
your parents must reach you during class time, please have them call
the front office to have a message delivered to you.
 Repeated cell phone violations will result in an office referral.
Be Informed
Make it a habit to regularly check your Geometry status using Skyward
and let me know if you find any errors. I expect you to take
responsibility for and ownership of your progress. Please let me know
if you need help with this. Please let me know if you have no internet
access and I will print paper progress reports for you.
Absences
Whenever possible, please avoid scheduling appointments
during math class. In the event of an unavoidable absence,
however, please do the following:
On the day(s) of the absence:




Check the teacher webpage to find out what you missed
in class that day.
Add the assignment (if any) to your Unit Organizer.
Correct your previous homework assignment.
If you feel well enough and have the time, try to do the
assignment from that day using the Holt online lessons
for help. http://my.hrw.com/
When you return to school:




Use the notebook in the back of the classroom to correct your assignment that was due on
the day of the absence.
Have the teacher stamp your assignment and organizer when (s)he checks the others.
Turn in your organizer (if you missed a Monday)
Make arrangements with the teacher to get extra help on what you missed, if needed.
Homework procedures and policies
10% of the grade
How much homework should I expect?
You should expect to be assigned Geometry for home practice 4-5 times per week. Homework
should take 20-30 minutes.

Correcting your homework
Any odd problems from the textbook
need to be corrected using the back of
your book, prior to coming to class. Even
answers will be corrected in class at the
beginning or end of class. You are responsible
for correcting your own paper and fixing your mistakes.
Please work with a neighbor to clean up your errors
before we discuss the assignment as a class.
“An error doesn’t become a mistake
until you refuse to correct it.”

Late Work
Late work is due on or before the Monday after the assignment was given. No work is taken late
after Monday, except in the case of excused absences.
If you have work to turn in late, please correct it, make your corrections, score it, and have me or the
TA stamp it at your desk.

Testing
90% of the grade
Quizzes
Quizzes will be given about every two lessons. Scores will be
recorded in the grade book as part of your summative assessment
grade. Quiz retakes are expected when the score is below standard
in order to prepare for the unit test. The retest score will replace the
first quiz score.
Testing
A unit test will be given at the end of each chapter or unit of study.
This handbook is always allowed on the unit tests. A section score
on the unit test may replace a lower quiz grade when initiated by the student using the procedure
expected by the teacher. THERE ARE NO RETAKES ON UNIT EXAMS.
Active Learning
While quiz and test scores must be the primary indicators of student learning, remember that how
you use your class time and whether or not you engage in the learning will ultimately determine your
preparedness for an exam. You will get out of your learning what you put into it. The following
behaviors will not be counted in your semester grade but will be reported on Skyward reports.
Non-academic behaviors that will be reported on Skyward:

Move over Stephen Covey!
7 Habits of Highly Effective Math Students (as penned by Mrs. Mulcahy )
Throughout the year, you will be given several opportunities to reflect on
and assess your progress in class. Though grades will inform you of your
learning, you may use the following “habits” to assess your behaviors that
contribute to learning.
Preparation


Come to class on time, with all required materials.
Complete your assignments on time, ready to be turned in at the beginning
of the period on the day they are due.
Engagement




Use your class time productively. Wasted time is wasted learning.
When doing an assignment, do more than write down answers to problems; work to understand
the concepts that are being studied.
Take careful notes in class.
Get actively involved in the lessons, both orally and mentally.
Practice


Complete your assignments on time, ready to be turned in at the beginning of the period on the
day they are due.
Participate in prescribed in-class individual or small-group practice.
Follow-through

When having trouble with an assignment, seek help from a friend, a teacher, the solution book,
or internet resources.
Feedback

Always correct your assignments using the resources provided.
Communication


Ask questions of a neighbor or the teacher when you have a question during the lesson.
Have someone that you can work on math with outside of class.
Praise



Support your friends and neighbors.
Congratulate others on a job well done.
Celebrate your own successes.

Diagonal Sudoku
Frame Sudoku
Use the digits 1 thru 9 vertically, horizontally,
diagonally, and in each square.
Use the digits 1 thru 9 so that the numbers in
the outside frame equal the sum of the first 3
numbers in the corresponding row or column in
the given direction.
Kakuro (cross sums)
KenKen
Use the number above, below or next to a row
or column to create the given sum. No digit may
be repeated in "the word" and no zeros are used.
Use the numbers 1 thru 6 to fill each row and column
so that each "cage" equals the target number using
the given operation.

Classroom Procedures & Expectations / CHAMPS
Transitions (time between activities) are opportunities for wasted time. The less time
we waste in class, the more time you will have for practice assignments, student
interviews, and other engaging activities. By learning these routines and
expectations, we will cut down on lost class time and complete our “jobs” more
quickly.
