INTEGER WEBQUEST

INTRODUCTION:

How often do you use integers in your daily life? More than you think!! Integers are used every day when watching a sporting event, checking the temperature outside and playing games. We are going to gain knowledge to identify and work with integers that are found in our everyday world. Through this series of activities, you will answer the following questions:

- What is the connection between negative numbers and the real world?
- What rules exist for performing operations with integers?
- How can I prove to myself that these rules are true?

THE TASK:

Your assignment is to use the websites provided to complete a series of activities. You will need to develop well explained answers to the questions. Your answers will need to be recorded on the handouts given to you. The answers to the questions need to be written in complete sentences using correct spelling, grammar and punctuation. The final answers need to be written legibly.

SECTION ONE:

COORDINATE PLANE

Click on the following links to practice graphing points on the coordinate plane. For each game you are going to rate it based on the following: directions, difficulty and enjoyment. Record your ratings and score in the Coordinate Plane Activities section of the Integer Webquest packet.

SECTION TWO:

HISTORY OF NEGATIVE INTEGERS

Use the websites below to answer these questions. Be sure to write the answers to the questions in your own words. You will not receive any credit for answers that are copied directly from a website. Write your answers to these questions in the History of Negative Integers section of the Integer Webquest packet. A clear understandable answer written in complete sentences is required.

Questions to be researched:
1. In what century were negative integers finally accepted?
2. Which cultures were the first to use negative integers and what contributions did they make?
3. When was the word integer introduced?
4. What does the word integer mean in Latin?
5. What is the symbol for integers, where does it comes from and what does it mean?

SECTION THREE:

RULES FOR INTEGER OPERATIONS

Use the websites below to answer these questions. You need to include an example with each of the explanations. Be sure to write the answers to the questions in your own words. Your explanation needs to include the math you do and how you determine the sign of your answer. Make sure you use the correct math terminology in your explanations. Write your explanation and example in the Rules for Integer Operations section of the Integer Webquest packet.

Questions to be researched:
1. How do you add two integers if they have the same sign? Make sure that you explain how to determine the sum’s sign.
2. How do you add two integers if they have different signs? Again, explain how to determine the sum’s sign.
3. Explain how you determine a difference when subtracting two integers.
4. Explain how you multiply and divide integers. A chart is acceptable as part of your answer.

SECTION FOUR:

INTEGERS AND EVERYDAY LIFE

Visit the websites listed to find examples of real life uses of integers, particularly the addition and subtraction of negative numbers. Identify three instances where integers are used in your everyday life. Provide a solid explanation that demonstrates your understanding of how the integers are involved with the examples that you identify. You will not receive credit for explanantions or examples that are copied directly from a website. The explanations must include how BOTH POSITIVE AND NEGATIVE numbers are used. Write these explanations in the Integers and Everyday Life section of the Integer Webquest packet.

SECTION FIVE:

REAL-LIFE WORD PROBLEMS

Write THREE, ORIGINAL real-life word problems. You must write one addition, one subtraction and one multiplication or division word problem. Each problem that YOU create MUST use NEGATIVE and POSITIVE integers. No credit will be given for examples that are copied from a website. The word problems need to be realistic (i.e. you cannot have -3 marbles). These three word problems and their solutions are to be written in the Real-Life Word Problems section of the Integer Webquest packet.

SECTION SIX:

PRACTICE WITH INTEGERS

Click on the following links to practice adding, subtracting, multiplying and dividing with integers. For each game you are going to rate it based on the following: directions, difficulty and enjoyment. Record your ratings and score in the Practice with Integers section of the Integer Webquest packet.
