Title: Rounding Off to the Nearest Tens

Grade Level: Class 3

Objective: - Students will understand the concept of rounding off numbers to the nearest tens. - Students will be able to round off numbers to the nearest tens using different strategies. - Students will apply rounding off skills to solve real-life problems.

Materials: - Whiteboard or blackboard - Markers or chalk - Number cards (0-9) - Worksheets with numbers for practice - Real-life examples for rounding off (e.g., prices, distances)

Procedure:

1. Introduction (5 minutes):
   • Begin the lesson by asking students if they have ever encountered numbers that are difficult to work with or understand.
   • Explain that rounding off numbers can make them easier to work with and understand.
   • State the objective of the lesson: to learn how to round off numbers to the nearest tens.
2. Review Place Value (10 minutes):
   • Recap the concept of place value, focusing on the tens place.
   • Write a few numbers on the board and ask students to identify the digit in the tens place.
   • Discuss the role of the tens place in determining the value of a number.
3. Rounding Off to the Nearest Tens (15 minutes):
   • Explain that rounding off to the nearest tens means finding the closest multiple of ten to a given number.
   • Demonstrate the rounding off process using examples on the board:
     • If the digit in the ones place is 0-4, the number remains the same.
     • If the digit in the ones place is 5-9, the number is rounded up to the next ten.
   • Practice rounding off numbers together as a class, using number cards or examples on the board.
4. Guided Practice (15 minutes):
   • Distribute worksheets with numbers for practice.
   • Instruct students to round off each number to the nearest tens and write the rounded number in the provided space.
   • Circulate the classroom to provide assistance and monitor progress.
   • Review the answers as a class, discussing any challenges or misconceptions.
5. Real-Life Application (10 minutes):
   • Provide real-life examples where rounding off to the nearest tens is useful (e.g., prices, distances).
   • Ask students to round off the given numbers and discuss their reasoning.
   • Encourage students to think about situations where rounding off can help in everyday life.
6. Independent Practice (10 minutes):
   • Assign additional practice problems from the textbook or worksheets.
   • Students should work individually to round off numbers to the nearest tens.
   • Collect and review the completed work to assess understanding.
7. Conclusion (5 minutes):
   • Recap the main points of the lesson, emphasizing the process of rounding off to the nearest tens.
   • Ask students to share any real-life situations where rounding off could be helpful.
   • Provide positive feedback and address any remaining questions or concerns.

Extension Activity: - For advanced students, introduce rounding off to the nearest hundreds or thousands. - Have students create their own real-life scenarios where rounding off to the nearest tens is necessary. - Encourage students to explore online rounding off games or interactive activities for further practice.

Note: The duration of each section can be adjusted based on the class’s pace and needs.
