Your Homework Checklist 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 Write down your answer clearly

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– Not circling the correct answers– 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
