Lesson Plan: Integers

Subject: Mathematics

Grade Level: 7

Duration: 30 Minutes

Objective

By the end of this lesson, students will be able to:

• Understand the concept of integers and their properties.
• Perform addition and subtraction with integers.
• Apply integers in real-life situations.

Materials Needed

• Whiteboard and markers
• Integer number line (visual aid)
• Worksheets for practice
• Colored pencils (optional)

Standards Alignment

This lesson aligns with the following Common Core State Standards for Mathematics:

• CCSS.MATH.CONTENT.7.NS.A.1: Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers.

Introduction (5 minutes)

1. Engage Students:

   • Ask students if they know what integers are.
   • Provide a brief definition: "Integers are whole numbers that can be positive, negative, or zero."
   • Display a number line on the board to illustrate the concept.

2. Relevance:

   • Discuss where integers are seen in real life (e.g., temperatures, bank transactions, elevations).

Direct Instruction (10 minutes)

1. Properties of Integers:

   • Explain the properties of integers (e.g., closure property, commutative property, associative property).
   • Provide examples for each property using integers:
     • Closure Property: When adding two integers, the result is always an integer. (e.g., (3 + (-5) = -2))
     • Commutative Property: The order of numbers does not change the sum. (e.g., (a + b = b + a))

2. Adding Integers:

   • Explain how to add integers with examples:
     • Same signs: Add the absolute values and keep the common sign.
       • Example: (3 + 2 = 5), (-3 + (-2) = -5)
     • Different signs: Subtract the smaller absolute value from the larger absolute value and keep the sign of the larger absolute value.
       • Example: (3 + (-5) = -2)

3. Subtracting Integers:

   • Explain how to subtract integers using the rule: (a - b) is the same as (a + (-b)). Use examples to demonstrate:
     • Example: (5 - 3 = 2) and (5 - (-3) = 5 + 3 = 8)

Guided Practice (10 minutes)

1. Whole Class Activity:

   • Write a few integer addition and subtraction problems on the board and solve them as a class.
   • Encourage students to raise their hands to share their thinking about each problem.

2. Pair Work:

   • Have students pair up and complete a worksheet with integer addition and subtraction problems.
   • Circulate and provide assistance as needed.

Independent Practice (5 minutes)

• Assign 3-5 problems from the worksheet for students to complete on their own.
• Encourage them to use the number line for any difficult problems.

Closure (5 minutes)

1. Review Key Concepts:

   • Recap the main points of the lesson: What integers are, how to add and subtract them.

2. Exit Ticket:

   • Have students write down one fact they learned about integers and one question they still have.

3. Assign Homework:

   • Provide additional practice problems on integers for homework. Remind students to review their notes before attempting the assignment.

Assessment

• Monitor student understanding during pair work and independent practice.
• Review exit tickets to gauge comprehension and address remaining questions in the next class.

Reflection

• After the lesson, reflect on what went well and what could be improved for future lessons. Consider student engagement and understanding.
