Lesson Plan: Division and Long Division, Rounding

Subject: Mathematics

Grade Level: 4

Duration: 30 minutes

---

Objective

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

1. Understand the concept of division.
2. Perform long division with one-digit divisors.
3. Round numbers to the nearest ten.

Materials Needed

• Whiteboard and markers
• Division and long division worksheets
• Rounding number flashcards
• Timer
• Manipulatives (e.g., counters or blocks for visual aid)

Standards

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

• CCSS.MATH.CONTENT.4.NBT.B.6: Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors.
• CCSS.MATH.CONTENT.4.NBT.A.3: Use place value understanding to round multi-digit whole numbers to any place.

Lesson Outline

Introduction (5 minutes)

• Start with a brief review of division. Ask students if they remember what division means.
• Explain that division is the process of splitting a number into equal parts.
• Give a simple example: "If I have 12 apples and want to share them among 3 friends, how many apples does each friend get?"

Direct Instruction (10 minutes)

1. Division Concept Overview

• Explain that division is the opposite of multiplication.
• Introduce terms: dividend, divisor, quotient, and remainder.

2. Long Division

• Explain the long division process step-by-step.

• Use the example 256 ÷ 4:

  • Step 1: Divide the first digit (2) by 4.
  • Step 2: Since 2 is less than 4, consider the first two digits (25).
  • Step 3: How many times does 4 go into 25? (6 times).
  • Step 4: Multiply 6 by 4 and subtract from 25.
  • Step 5: Bring down the next digit (6) and repeat.

• Write the process clearly on the whiteboard.

Guided Practice (5 minutes)

• Provide students with a practice problem: "Divide 384 by 3 using long division."
• Walk around and assist students as they work through the problem.

Independent Practice (5 minutes)

• Hand out a worksheet with long division problems for students to complete on their own.
• Encourage them to check each other’s work in pairs.

Rounding (5 minutes)

• Transition into rounding numbers using rounding flashcards.

• Explain the rules:

  • If the digit is 0-4, round down.
  • If the digit is 5-9, round up.

• Give examples worth discussing as a class:

  • "Round 48 to the nearest ten."
  • "Round 76 to the nearest ten."

Closure (5 minutes)

• Review what students learned in the lesson.
• Ask students to share their thoughts on long division and rounding.
• Assign homework: Practice additional long division problems and rounding exercises.

---

Assessment

• Monitor student understanding through their participation during guided practice and completion of independent practice.
• Review the worksheets for accuracy in both long division and rounding.

Additional Notes

• Adjust explanations based on the needs of the students, using manipulatives as needed for visual learners.
• Incorporate group discussions to foster collaborative learning and problem-solving skills.
