Homework Policy:  Homework will be collected at the beginning of class on Tuesdays with some exceptions.   Homework will be graded out of 15 points; 6 points for completion, 9 points for the correctness of three selected problems from the homework.  Late homework will not be accepted.  At the end of the quarter, the lowest homework assignment will be dropped.

 

In order to receive credit for each assignment, it must be complete, on-time, and meet the following criteria:

    * Problem-solving steps must be shown clearly for all problems.

    * On standard size (8" x 11") paper with no fringed edges.

    * Pages must be stapled in order if there is more than 1 page.

    * Answers to word problems must be in complete sentences.

    * Graphs must be drawn with a straight edge and axes must be labeled and scaled.
