### Lesson Plan: Revision of Basic Operation of Integers
**Grade Level:** Senior Secondary 1
**Subject:** Mathematics
**Topic:** Revision of Basic Operation of Integers
**Duration:** 60 minutes
#### Learning Objectives:
By the end of the lesson, students should be able to:
1. Recall and apply the rules for addition, subtraction, multiplication, and division of integers.
2. Solve problems involving the four basic operations with integers.
3. Understand and apply the order of operations in problem-solving involving integers.
#### Materials Needed:
- Whiteboard and markers
- Handout with integer operations rules
- Worksheets with practice problems
- Calculators (optional)
- Graph paper
#### Lesson Structure:
**1. Introduction (10 minutes)**
*Greeting and Attendance:*
- Greet the students and take attendance.
*Motivation and Engage:*
- Begin with a brief discussion to gauge students' current understanding. Ask:
- "What are integers?"
- "Can anyone tell me what the basic operations on integers are?"
- "Why do you think understanding these operations is important?"
*Objectives Sharing:*
- Share the learning objectives and explain that today's lesson will focus on revising the basic operations on integers to prepare for more complex math problems.
**2. Direct Instruction (15 minutes)**
*Key Concepts Review:*
- **Addition of Integers:** Explain and give examples.
- Rule: Positive + Positive = Positive, Negative + Negative = Negative, Positive + Negative (or vice versa) = depends on the values, subtract and take the sign of the larger absolute value.
- **Subtraction of Integers:** Explain and give examples.
- Rule: Convert subtraction into addition. For example, \(a - b = a + (-b)\).
- **Multiplication of Integers:** Explain and give examples.
- Rule: Positive * Positive = Positive, Negative * Negative = Positive, Positive * Negative (or vice versa) = Negative.
- **Division of Integers:** Explain and give examples.
- Rule: Similar to multiplication, Positive / Positive = Positive, Negative / Negative = Positive, Positive / Negative (or vice versa) = Negative.
*Order of Operations:*
- Review PEMDAS/BODMAS for handling operations in expressions.
- Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right).
**3. Guided Practice (15 minutes)**
*Example Problems:*
- Work through examples on the board with student participation.
- Example 1: \( (-5) + 7 = 2 \)
- Example 2: \( 12 - (-4) = 12 + 4 = 16 \)
- Example 3: \( (-3) \times (-6) = 18 \)
- Example 4: \( 15 \div (-3) = -5 \)
*Practice Problems:*
- Distribute worksheets with practice problems. Work through a couple of problems together before letting students attempt the remaining on their own.
- Example Sheet may include:
- \( 6 - (-8) \)
- \( (-7) + 9 \)
- \( (-4) \times 5 \)
- \( (-36) \div 6 \)
- \( 4 + (-3) \times 2 \)
**4. Independent Practice (15 minutes)**
*Worksheet Completion:*
- Students work independently on the worksheet provided.
- Monitor and assist students as needed, ensuring they understand the rules and concepts.
**5. Review and Assessment (5 minutes)**
*Homework Assignment:*
- Assign a few additional practice problems for homework to reinforce the lesson.
*Exit Ticket:*
- Quick assessment: Ask each student to solve one problem on a small piece of paper or note card before leaving.
- E.g., \( (-5) + 10 = ? \)
**6. Conclusion and Wrap-Up (5 minutes)**
*Recap Key Points:*
- Summarize the main points of the lesson.
- Answer any remaining questions from students.
*Feedback:*
- Ask students about their comfort level with the material, and if there are areas that need further clarification.
#### Follow-up Activities:
- Plan a quiz in the next class to assess students' grasp of integer operations.
- Include more complex problems combining different operations and larger integers to further challenge students.
#### Evaluation:
- Observe students during guided and independent practice to evaluate their understanding.
- Use the exit ticket and homework assignment to assess individual student progress and provide feedback.
This structured lesson plan ensures a comprehensive review of the basic operations of integers, reinforcing students' foundational skills as they prepare for advanced mathematical concepts.
