Lesson Plan: Division

Subject: Mathematics

Grade: 4

Duration: 30 Minutes

Topic: Division

Objectives

• Students will understand the concept of division as sharing or grouping.
• Students will be able to divide numbers using basic division facts.
• Students will begin to understand division with remainders.

Materials Needed

• Whiteboard and markers
• Division flashcards
• Worksheets with division problems
• Manipulatives (counters or blocks)

Lesson Outline

Introduction (5 Minutes)

1. Warm-Up Activity: Start with a quick review of multiplication to illustrate the relationship between multiplication and division. Ask students questions like "What is 3 times 4?" and then relate it to division: "If we have 12 and we want to share it equally among 3 friends, how would we do that?"

2. Define Division: Introduce the concept of division as the process of splitting into equal parts or groups. Write the division symbol (÷) on the board and explain that it's used to indicate division.

Direct Instruction (10 Minutes)

1. Division as Sharing: Use manipulatives to demonstrate division. For example, if you have 12 blocks and 3 students, show how to distribute the blocks equally among the students. Each student would receive 4 blocks.

2. Visual Representation: Draw diagrams or use number lines to show how division works. For instance, illustrate 15 ÷ 5 by showing 15 dots grouped into 5 equal parts.

3. Discuss Remainders: Introduce the idea of remainders with a simple example, such as 17 ÷ 5. Show that 5 fits into 17 three times (making 15) and that 2 remains.

Guided Practice (10 Minutes)

1. Group Activity: Divide the students into pairs and give each pair a set of division flashcards. Ask them to take turns quizzing each other on their division facts (e.g., 8 ÷ 4, 16 ÷ 4).

2. Worksheet: Hand out a worksheet with problems that require both straightforward division and some problems involving remainders. Example problems:

   • 12 ÷ 4 = ?
   • 20 ÷ 5 = ?
   • 18 ÷ 7 = ?

3. Review Answers: Go over the worksheet together as a class, checking answers and discussing any errors.

Independent Practice / Homework (5 Minutes)

1. Homework Assignment: Distribute the homework worksheet with the following tasks:
   • Solve the following problems:
     1. 24 ÷ 6 = ?
     2. 30 ÷ 5 = ?
     3. 22 ÷ 4 = ?
     4. 35 ÷ 6 = ?

Correct Answers for Homework

1. 24 ÷ 6 = 4
2. 30 ÷ 5 = 6
3. 22 ÷ 4 = 5 R2 (5 with a remainder of 2)
4. 35 ÷ 6 = 5 R5 (5 with a remainder of 5)

Conclusion (5 Minutes)

• Recap the lesson by asking students to share what they learned about division.
• Emphasize the importance of understanding division in real-life situations, such as sharing items or dividing into groups.
• Encourage students to look for division opportunities in their everyday lives and to practice their division facts.

Assessment

• Collect the homework assignments to assess understanding.
• Observe group interactions and participation during guided practice.

Extensions

• For students who finish early, provide additional challenges involving larger numbers or more complex division problems.
