Lesson Plan: Rounding Numbers

Subject: Mathematics

Grade: 5

Duration: 30 minutes

Topic: Rounding Numbers

---

Objectives

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

1. Understand the concept of rounding numbers.
2. Round whole numbers to the nearest ten and nearest hundred.
3. Apply rounding skills in problem-solving situations.

---

Materials Needed

• Whiteboard and markers
• Rounding number charts (one for each student)
• Worksheets with rounding exercises
• Small number cards (1-100)
• Counters or small tokens (optional for hands-on activities)

---

Introduction (5 minutes)

1. Begin the lesson by asking students what they know about rounding numbers. Encourage them to share their thoughts and previous experiences.
2. Introduce the concept of rounding by explaining that it is a way to make numbers easier to work with by finding the nearest ten or hundred.
3. Write an example on the whiteboard: “What is 37 rounded to the nearest ten?”

Direct Instruction (10 minutes)

Rounding to the Nearest Ten

• Explain the rules of rounding:

  • If the digit in the ones place is 5 or greater, round up.
  • If the digit in the ones place is less than 5, round down.

• Provide more examples:

  • 43 → 40 (round down)
  • 67 → 70 (round up)

Rounding to the Nearest Hundred

• Explain the rules of rounding to the nearest hundred:

  • If the digit in the tens place is 5 or greater, round up.
  • If the digit in the tens place is less than 5, round down.

• Provide examples:

  • 234 → 200 (round down)
  • 576 → 600 (round up)

Guided Practice (10 minutes)

Activity 1: Rounding Exercise

1. Distribute the rounding worksheets to each student.
2. Have students work on rounding a set of numbers to the nearest ten and nearest hundred.
3. Walk around to provide assistance and monitor student understanding.
4. After 5 minutes, review the answers together as a class, allowing students to share their reasoning.

Activity 2: Rounding with Number Cards

1. Divide the class into small groups and provide each group with a set of numbered cards (1-100).
2. Ask each group to select a number and round it to the nearest ten and hundred, discussing their choices amongst themselves.
3. Have a representative from each group share their selected number and the rounded values with the class.

---

Independent Practice (5 minutes)

Encourage students to complete a short quiz that includes:

• Rounding three different numbers to the nearest ten.
• Rounding three different numbers to the nearest hundred.

---

Conclusion (5 minutes)

1. Review the key points of the lesson, reinforcing the rules for rounding.
2. Ask students to share one thing they learned about rounding numbers today.
3. Explain how rounding is useful in real-life situations, such as estimating costs or making quick calculations.

---

Assessment

• Evaluate students' understanding through their completed worksheets and quizzes.
• Observe group discussions during activities to assess collaborative understanding.

---

By following this lesson plan, students should have a better grasp of rounding numbers and be able to apply this knowledge to future math problems.
