Operations with Integers

Introduction

This Webquest has been taken from INTEREGERS WEBQUEST by Paul Brown, David A. Brown Middle School.

Introduction

You recently graduated college and have been spending time looking for a job.  In the Classified Section of you local newspaper, you came across an employment opportunity for a new magazine called "Mathematics Monthly"  You contacted the magazine about the position.  After going in for an interview, the owner of the magazine was very impressed with you.  He was also very impressed with several other candidates.  To help decide who to hire, he developed a webquest for you to go through to see who would be the best person for the job.  In this webquest, you are going to find out about the history of integers, learn some different ways to add, subtract, multiply, and divide integers, critique some online math games, and find out how integers are used in the real world.  Whichever candidate does the best job is going to get hired.  Good luck!   

 

Task

Task

 

For this webquest you will do research for a magazine about integers.  By investigating various links and completing worksheets you will do the following:

1)Write about the history of integers

2)Write 3 common ways to add and subtract integers. 

3)Write an paragraph on which method you like the best when it comes to adding and subtracting integers.

4)Give three examples (in paragraph form) about how integers are used in the real world

5)Write 2 reviews of online integer games.

Process

Process

HISTORY OF  INTEGERS⇒PART 1

Your first job is going to be doing some research on the history of integers.  On the handout are some questions for you to answer.  Please use the following websites to do your research.

 INTEGERS

LATIN WORDS

CLASS ZONE

ASK DR. MATH

HISTORY OF ZERO

NEGATIVE NUMBERS

 

 

ADDING AND SUBTRACTING INTEGERS⇒PART 2

The next step is to do some investigating about some common ways to add and subtract integers.  Use the websites/videos below to gather your information.  For each of the ways fill out the HANDOUT which has questions for you to answer.

METHOD 1 NUMBER LINE

 VIRTUAL NERD 1

VIRTUAL NERD 2

 

METHOD 2 ABSOLUTE VALUE 

AMBY.COM

 

METHOD 3 TILES

Now that you have finished gathering information on adding and subtracting integers, write a paragraph about which method you like to use best and why?  PLEASE BE SPECIFIC IN YOUR ANSWER.  DON'T JUST SAY IT'S EASY OR BECAUSE THE OTHER ONES WERE DIFFICULT.

 

MULTIPLYING AND DIVIDING INTEGERS⇒PART 3

Use the links below to create a colorful advertisement that shows how to multiply and divide integers.  Be sure to include how to tell if the answer is negative or positive. This will go in your magazine.

INTEGERS IN THE REAL WORLD⇒PART 4

 

Use the links below to find examples of how integers are used in the real world  Focus on adding and subtracting integers.  Come up with three examples of how integers are use in your everyday life, one example must be one you created NOT FOUND.  PLEASE MAKE SURE YOU EXPLAIN HOW BOTH POSITIVE AND NEGATIVE NUMBERS ARE USED.

Advertisement is somewhat colorful.  Confusing is the answer is negative or positive.

Advertisement is very colorful.  Clearly explains how to tell if a number is negative or positive.

Examples of Integers in the Real World  Does not clearly explain how integers are used in their daily life.  Copies all examples from links. Clearly shows their understanding of how integers (both positive and negative) are used in their daily life.  Includes examples. Does not copy all examples from links.
Review of Online Integer Games One review is written that addresses some of the answers to the questions on the Integer Game Critique Handout.  Two reviews are written that addresses some of the answers to the questions on the Integer Game Critique Handout.  One reviews are written that clearly address all the answers to the questions for each game on the Integer Game Critique Handouts.  Two reviews are written that clearly address all the answers to the questions for each game on the Integer Game Critique
Conclusion

Conclusion

Congratulations! You finished your first webquest.  I hope you learned a lot about integers and had fun making your magazine.  Be sure to turn your magazine in to Mathematics Monthly!  I hope you get the job!
