7th Grade Integer Webquest

7th GRADE

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. Can you use the knowledge you have learned in the classroom to identify and work with integers that are found in your 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:

INTEGER VOCABULARY

Use the vocabulary websites below to define these words. Be sure to give your own example for each word. Record the definitions and examples on the Integer Vocabulary handout.

1. integer
2. negative number
3. positive number
4. opposite
5. absolute value

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. Record your answers on the History of Negative Integers handout. 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 WORKING WITH INTEGERS AND OPERATIONS ON INTEGERS

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. A solid, understandable explanation is required for each question. Make sure you use the correct math terminology in your explanations. Record your answers on the Rules for Working with Integers and Operations on Integers handout.

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 that have the same signs.
4. Explain how you determine a difference when subtracting two integers that have different signs.
5. Explain how you multiply and divide integers. A chart is acceptable as part of your answer.

SECTION FOUR:

INTEGERS AND EVERYDAY LIFE

1. 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. These examples are to be explained on the paper that is titled, Integers in the Everyday Life.

SECTION FIVE:

REAL-LIFE WORD PROBLEMS

Create FOUR, ORIGINAL real-life word problems that involve each of the four basic operations of subtraction, addition, division, and multiplication. 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 four problems, and their solutions are to be recorded on the paper titled, Integer Real-Life Word Problems.

SECTION SIX:

PRACTICE WITH INTEGERS

Click on the following links to practice adding, subtracting, multiplying and dividing integers. At each website scroll down to the "PLAY" section and press "Countdown." How many correct answers can you get in 60 seconds? Record the number you get correct on the Practice with Integers Handout. Have fun!!!
