Geometry



Advanced Algebra/Precalculus: Problem Sets

2nd Term

READ THE DIRECTIONS CAREFULLY!

• Problem sets are designed to review concepts taught in previous courses as well as those taught in this class. Problem sets must be taken seriously and emphasis should be on the process to answer each question and not necessarily the answer itself.

• Problem sets are due according to the schedule below. Points are deducted for each day late. If you are absent on the due date, it is YOUR responsibility to turn in the assignment on the first day back to school. Absences for school related activities (sports, field trips, club activities, etc.) DO NOT excuse you from submitting problem sets on the due date. You can take a picture of your problem set and send it in if you are out!

• You may seek help any time before the due date. STUDENTS ARE NOT ALLOWED TO ASK FOR HELP ON THE DAY IT IS DUE!!! Students must also have work to show the teacher before asking questions.

• Work must be shown to receive credit. Work done on a separate sheet of paper must be securely attached to the actual problem set. Calculations performed on a calculator must be shown on the paper.

• You MUST earn a minimum of 50% on EACH problem set to earn quarter mastery grade.

Packet Due at the BEGINNING of class on or before the class date:

1 11/30 or 12/1

2 12/14 or 12/15

3 1/11 or 1/12

REMINDER – NO Problem set = NO grade replacement from Cumulative Quarter Test!
