Lesson Plan: Rounding

Subject: Mathematics

Grade Level: 3

Duration: 30 Minutes

Topic: Rounding

Objective:

Students will learn how to round numbers to the nearest ten and the nearest hundred.

Materials Needed:

• Whiteboard and markers
• Rounding number chart
• Handouts with rounding exercises
• Homework assignments

Lesson Structure:

Introduction (5 minutes)

1. Begin the lesson by engaging students with a question: "Why do we round numbers?"
2. Provide real-life examples of rounding, such as estimating prices or distances.

Instruction (10 minutes)

1. Explain the concept of rounding. Use simple terms to define rounding as making a number simpler but keeping it close to what it was.
2. Introduce the rules for rounding:
   • If the digit in the ones place is 5 or more, round up.
   • If the digit in the ones place is less than 5, round down.
3. Write examples on the board:
   • Rounding to the nearest ten:
     • 34 → 30 (down)
     • 36 → 40 (up)
   • Rounding to the nearest hundred:
     • 245 → 200 (down)
     • 254 → 300 (up)

Guided Practice (10 minutes)

1. Work through several problems as a class:
   • Round 72 to the nearest ten.
   • Round 89 to the nearest ten.
   • Round 462 to the nearest hundred.
   • Round 520 to the nearest hundred.
2. Ask students to repeat the rounding rules. Ensure they understand how to identify the digit that determines whether to round up or down.

Independent Practice (5 minutes)

1. Hand out the rounding exercises and give students time to complete them individually.
2. Walk around the room to provide support as needed.

Closure (5 minutes)

1. Review the answers to the independent practice exercise as a class.
2. Summarize the key points discussed about rounding. Reinforce why rounding can be helpful.

Homework Assignment:

Complete the following rounding exercises:

1. Round the following numbers to the nearest ten:

   • a) 27
   • b) 54
   • c) 92

2. Round the following numbers to the nearest hundred:

   • a) 135
   • b) 499
   • c) 652

Answers to Homework:

1. Rounding to the nearest ten:

   • a) 27 → 30
   • b) 54 → 50
   • c) 92 → 90

2. Rounding to the nearest hundred:

   • a) 135 → 100
   • b) 499 → 500
   • c) 652 → 700

Assessment:

Evaluate student understanding through:

• Participation during guided practice
• Completion of independent practice
• Accuracy of homework responses

Reflection:

Post-lesson review to consider what went well and what could be improved for future lessons on rounding.
