 On the first page of each homework section:
 Put your Name & Assignment in the right top corner of first page
 For each problem:
 Write problem number and the original problem (word problems: summarize briefly)
 Write down intermediate work steps – most problems will have them
 Suggested - Every 5 problems:
 Check these 5 answers in the back of the textbook
 Correct any wrong answers (if you can ) by fixing the work steps
 Circle only the correct answers.
 Mark any wrong or missing answers with a big X – do not circle or count as correct!
 Use both front and back pages but leave a little space between problems
 After working all the problems that you can, determine the SCORE:
 Count the number of correct problems
 Get the number of assigned problems from the assignment line {##}
 Your SCORE is the ratio of correct problems to the total assigned. Example: 27
31
 Write the SCORE at the page top just left of your name
 If more than one page was used for this section, Staple them together top left
 When it’s time to Submit one of the 13 Homework Submissions:
 Staple (top left) the 3 to 5 sections together, in order
 Pass in to me for Grading (0 to 10 points) based on percentage of problems done correctly
Some Common Mistakes
• Mistakes with the first homework submissions:
–
–
–
–
–
–
–
–
–
Format wrong: Score, Name & Assignment not in right corner of first page
Missing the Score (# of correct)/{# of assigned}
The Score is not accurate
Not writing down the original problem
Incomplete H/W: whole section missing, or too many problems missing
Messy, disorganized or cramped work
Failure to use the vertical approach, where appropriate
EOO failure, did some wrong problems (this is ok occasionally)
• Practices that may be considered Cheating (Inflating your Score)
–
–
–
–
Not checking answers in back of the book
Missing work steps, when appropriate
Answer is right, but does not match work (you and I will meet to discuss)
Not clearly identifying incorrect answers (if you left them wrong):
Put a BIG X over the incorrect or missing answer
