Supplies Needed:  3-ring binder with dividers, graph paper, spiral or notebook paper, pencils, graphing calculator (TI-84)


Tests:  Tests will be given at the end of a unit.  Review assignments will be given prior to each test. There will be a final exam at the end of each semester.


Quizzes: These are both announced and unannounced.  If you are dissatisfied with your quiz grade, you will be given approximately one week to make corrections to better the grade. Watch for due dates in class! Please see Mrs. Le Jean to make an appointment for quiz corrections. All quizzes must be completed before the unit test.


Daily Quizzes:  This assignment will be completed at the beginning of the class period.  Students will self-grade during class and are responsible for recording the score.  I would suggest keeping all work in a spiral notebook for this assignment.


Homework:  Students should expect to work on homework every day.  Homework is distributed by unit in class and also accessible from my website.  All homework assignments for the unit are due on the

DAY OF the unit TEST.  ALL work must be shown.  LATE homework will be accepted up until one week after the unit test for a reduced grade.



It is important to be on time to class every day.  Within the first 5 minutes of class, I will mark absent students. If you are tardy, please see Mrs. Le Jean at the end of class to change your absence to a tardy. There shall be two days allowed for makeup work for each day of absence.

Please see Mrs. Le Jean when you return from an absence!


Technology in the Classroom

All phones, head-phones, and any other electronic devices are to be off and put away during class. 

Teachers may determine when cell phones and other technology are to be used for educational purposes.


1st Offense: Warning

2nd Offense: Teacher takes the device

3rd Offense: Teacher takes the device and brings it to the student's administrator. 


Please do not text/call your student during class time.  If there is an emergency, please call the main office to have your student excused from class.
