It is great to go back and look at problems you previously missed.  This way you will have more learning! If you would like to turn in edited work, you can receive higher credit on a corrected assignment or test.  To earn credit for your corrections, follow the directions below.

 

HOMEWORK:

  • Corrections must be on a separate sheet of paper that is stapled to the assignment.
  • You must clearly label which problems you missed and are editing.
  • For each assignment, you must rework ALL of the problems you have missed 
  • DO NOT correct on the original paper.
  • MUST BE DONE WITHIN ONE WEEK OF THE DAY THE ASSIGNMENT WAS RETURNED OR WHEN TEACHER DESIGNATES.

 

ASSESSMENTS:

  • Corrections must be on a separate sheet of paper that is stapled to the assessment.
  • You must clearly label which problems you missed and are editing.
  • For each problem, you must write an explanation about what the original mistake was and why the new way you did the problem is correct. 
  • This is a “verbal proof” of the problem.
  • DO NOT correct on the original paper.
  • MUST BE DONE WITHIN ONE WEEK OF THE DAY THE TEST WAS RETURNED OR WHEN TEACHER DESIGNATES.

 

An Example of How to Edit ‘til You Get It

Original Question and incorrect answer:

At a store, hot dogs come in packages of ten and hot dog buns come in packages of six. What is the least number of packages of each type that you can buy and have no hot dogs or buns left over.   Remember to label your numbers and show your work.

 

Hot Dogs (10) – 1, 2, 5, 10

Hot Dog Buns (6) – 1, 2, 3, 6                              Answer = 2

 

Edited Version:

I got this problem wrong because I found the factors of the packages instead of the multiples.   I also did not write a complete labeled sentence for my answer.  What I should have done was find the multiples of each package and from that find the Least Common Multiple (LCM).

 

Hot Dogs (10) – 10, 20, 30, 40, 50

Hot Dog Buns (6) – 6, 12, 18, 24, 30, 

 

Since the LCM of both products is 30 that means I would have to by three packages of Hot Dogs and five packages of Hot Dog Buns in order to not have any left over food. I know this because Hot Dogs come in packages of ten and 3010 = 3 packages and Hot Dog Buns come in packages of six and

306 = 5 packages
