Objective: The student will become an expert on the history of integers, the rules
of integers, and real-world application problems.
Activities: The student will complete the following activities:
 Using the websites provided, you will need to develop well explained
answers to the questions that follow. By completing the questions you
will be doing research on integers. Your research will be completed on
the internet, using SPECIFIC websites.
 Your research will be recorded using Microsoft Word documents.
 You will need to complete the project according to its instructions and
requirements.
 Your project will be displayed on a poster or in a booklet.
 DATE DUE: OCTOBER 17, 2013
 5 points will be deducted for every day that it is late
Part I: Working with Integers

http://www.mathguide.com/lessons/Integers.html
Use the Rules for Integers and Operations on Integers to help you research your
answers for questions 6-10.
6. How do you add two integers if they have the same sign? Make sure that
you explain how to determine the sum’s sign.
7. How do you add two integers if they have different signs? Again, make sure
that you explain how to determine the sum’s sign.
8. Explain how you determine a difference when subtracting two integers that
have the same sign. A solid, understandable explanation is required.
9. Explain how you determine a difference when subtracting two integers that
have different signs. A solid, understandable explanation is required.
10. Explain how you multiply and divide integers. Provide a solid explanation. A
chart is acceptable as part of your answer.
PART II: INTEGERS IN THE EVERYDAY-WORLD
Use Microsoft Word for the following questions.
1. Identify three examples of how integers are used in your everyday world.
Provide a solid explanation. On the poster, a picture for each example is to
be displayed and an explanation next to the picture.
2. Create FOUR, real-world application problems that involve each of the four
basic operations of addition, subtraction, multiplication and division. Each
problem that you create MUST use negative and positive integers. These
problems AND their SOLUTIONS will be submitted on a separate piece of
paper titled, “Integer Word Problems”. This will be displayed on the back
of your poster.
