Title:

The World of Integers

Overview/Annotation:

The objective of this lesson is for students to review the basic operations of rational numbers – Integers. This lesson is design as a technology-based project; webquest, that focus on adding and subtracting integers with the extension of multiplying and dividing integers. This lesson requires students to focus on how integers are used in real world situations.

 

Content Standard(s):
MA2013(6) 9. Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates. [6-NS6]
MA2013(7) 4. Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. [7-NS1]
MA2013(7) 5. Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. [7-NS2]
Local/National Standards:

Primary Learning Objective(s):

At the completion of this webquest lesson, students will understand how to apply the rules for adding, subtracting, multiplying, and dividing integers. Students will also understand and see how integers are applied to their daily lives.

Additional Learning Objective(s):

The students will read various articles on integers, and how they impact their daily lives. Students will use a graphic organizer to complete this assignment.

 

Approximate Duration of the Lesson: Greater than 120 Minutes
Materials and Equipment:

Pre-Assessment; Graphic organizer; Integers – signed numbers activity sheet; Post-Assessment; math journals; chart paper; markers.

 


 

Technology Resources Needed:

Netbooks and laptop with Internet capabilities for digital projector.

 

The World of Integers website

 

Background/Preparation:

Students must understand rational numbers, and how to graph and add integers on a number line. Teacher will review whole numbers, natural numbers, rational numbers, and integers to make sure that students understand and are prepared to complete the webquest.

Procedures/Activities:

Step 1

Engage students by having them to classify rational numbers by being natural, whole and integers. Students will also demonstrate how to add integers by using a number line.

Students will view a Presentation on Interesting Integers. This presentation discuss the rules for adding, subtracting, multiplying, and dividing integers. Many examples are used to help students master the concepts of integers.

Interesting Integers presentation is found at

 

http://www.math.pppst.com/integers.html.

The students will also have a pre-assessment on adding and subtracting integers at the beginning of the webquest assignment to assess prior knowledge of integers. This assesment called Integers-Signed Numbers can be found at

Step 2

 

After the conclusion of the presentation on Interesting Integers, students will be divided into groups of fours to complete a reading assignment on the use of integers in our everyday lives. The group is assigned a facilitator to keep all members on task. Each group is assign to a specific website to read and discuss their article related to integers. Then they will fill out a graphic organizer of questions pertaining to the article.The articles are found at

Step 3


The students are invited to play games relating to integers. One such game is Line Jumper at Fun Brain, found at

 http://www.funbrain.com/linejump/index.html.

Students must select a level of difficulty ranging from a level of easy - a number line between 0 and 10, to super brain-a number line between -16 and 16 with negatives moves. They are shown a number line and a math question. The students must click on the number line at the correct answer to the question. Students may work along, or play against the computer. The highest scorer wins.

Step 4

The students were also invited to play another game.

Title: Math Car Racing

URL: http://www.funbrain.com/cgi-bin/osa.cgi.

Annotation: To play Math Car Racing, the students must click on an expression from the row that is highlighted (side to side). Fun Brain will choose an expression from the same column as the student, but (up and down). Whoever has the most points, which is based on the level of difficulty, wins.

These are games that re-enforce students understanding of integers and how they are used daily.

Step 5

The students must create a one page flyer on integers. This is a group assignment. Each group is given a sheet of chart paper and a box of markers. The group must create a flyer providing how integers are used in the real world, as well as any other information about integers that they deemed are important.

The rubric used to assess the flyers that the students create is found at

 The post-assessment is attached.

Assessment Strategies:

The students were given a pre-assessment on adding and subtracting integers at the beginning of the webquest assignment. At the conclusion of the webquest, students will have a post-assessment on adding and subtracting integers.

 Students will have to demonstrate or write the rules for adding and subtracting integers. They also may be asked to demonstrate how to add integers by using a number line.

 

Each group will share their Integer flyer with the class, and tell how integers are used everyday. They will also get to share their experience with their first webquest.

 

 

Extension:

The World of Integers webquest could be modified to address multiplying and dividing integers. Solving equations using addition, subtraction, multiplication, and division can also be introduce to challenge students.

Remediation:

Students that need reinforcement or enrichment may be allowed to revisit the various websites in the webquest. If students continue to have problems, they will get assistance from the teacher. Manipulatives may be used to demonstrate how to add, subtract, multiply or divide integers.

Each area below is a direct link to general teaching strategies/classroom accommodations for students with identified learning and/or behavior problems such as: reading or math performance below grade level; test or classroom assignments/quizzes at a failing level; failure to complete assignments independently; difficulty with short-term memory, abstract concepts, staying on task, or following directions; poor peer interaction or temper tantrums, and other learning or behavior problems.
