									            How to make QUIZ corrections!
It is great to go back and look at problems you previously missed. This helps you have a
better understanding of the concepts you may be unsure of. You have the opportunity to
make corrections on all quizzes and receive a higher grade. To earn credit for your
corrections, follow the directions below.

QUIZ CORRECTIONS
  1. Corrections must be on a separate piece of paper that is stapled to the front of
      the original quiz.
  2. You must clearly label which problems you missed and are editing.
  3. For each problem, re-work the problem showing all work and write a
     short paragraph that explains how to solve the problem correctly.
    The new answer must be clearly stated. Your explanation should include
     key concepts learned in class. Use your Learning Log entries to support
     your explanations.
  4. QUIZ CORRECTIONS MUST BE TURNED IN ON THE DUE DATE
      ASSIGNED.


   Here is an example of an edited problem…
   Question: Find the perimeter of the rectangle.                                 2 cm


   Student’s original answer:                                         5.7 cm


      5.7
      5.7
        2          The perimeter is 11.8.
    + 2
     11.8

      2.0          The perimeter is 15.4 cm.
    + 2.0
     15.4
   Perimeter is the sum of all the side lengths. I needed to line the decimals up in order
   to add the side lengths correctly and my answer needed to have units of measure.
Question: What is the area of the rectangle?                                  2 cm

Student’s original answer:                                        5.7 cm


  5.7 x 2 = 114     The area is 114 cm.

Quiz Corrections answer:

   A = lw

  5.7 x 2 = 11.4    The area is 11.4 cm2.

The area of a rectangle is length times width. Multiply 5.7 times 2 and make sure you
get the decimal in the right place. When giving units of measure for area, the units
must be squared.


                                                                           2 cm
Question: What is the scale factor from A to B?             A


Student’s original answer:                                 6 cm              B       1 cm

                                                                           3 cm
  The scale factor is 1/2.

Quiz Corrections answer:

   3÷6=½

   The scale factor from A to B is ½.

When giving a scale factor answer, you must say from which figure to which figure
because there are 2 scale factors between figures. The scale factor is ½ because the
side length of B are ½ the side lengths of A. If I multiply 6cm on figure A by ½ I get
the corresponding side length of 3 cm on figure B.
