Lesson Plan: Whole Numbers 1 to 999
Grade: Primary 3
Subject: Mathematics
Topic: Whole Numbers 1 to 999
Duration: 60 minutes
Objective:
By the end of the lesson, students will be able to:
1. Identify and write whole numbers from 1 to 999.
2. Understand place values (units, tens, and hundreds).
3. Compare and order whole numbers within the range of 1 to 999.
Materials Needed:
1. Whiteboard and markers
2. Number cards (1 to 999)
3. Place value charts
4. Worksheets with exercises on whole numbers
5. Manipulatives such as base-ten blocks (optional)
Introduction (10 minutes):
1. Begin with a brief discussion on what whole numbers are, asking students to provide examples.
2. Write the numbers 1 to 999 on the whiteboard in a list.
3. Explain that whole numbers are the numbers without fractions or decimals.
Direct Instruction (20 minutes):
1. Introduce place values using a place value chart. Explain the units, tens, and hundreds places.
- Example: Show the number 512 and break it down as 5 hundreds, 1 ten, and 2 units.
2. Using number cards or base-ten blocks, demonstrate how to construct numbers in the range of 1 to 999.
Guided Practice (10 minutes):
1. Distribute number cards or use manipulatives, and have students represent different numbers in the 1 to 999 range by placing them correctly on the place value chart.
2. Write a few numbers on the whiteboard and ask students to break them down into units, tens, and hundreds.
Independent Practice (15 minutes):
1. Distribute worksheets with various exercises:
- Identify and write whole numbers.
- Decompose and recombine numbers into units, tens, and hundreds.
- Compare two or more numbers and arrange them in ascending or descending order.
2. Circulate the room to provide assistance and ensure students are on task.
Closure (5 minutes):
1. Review the key concepts covered in the lesson:
- What are whole numbers?
- How do we identify place values?
- How can we compare and order whole numbers?
2. Encourage students to ask any questions they may have.
Assessment:
1. Review the completed worksheets to assess the students' understanding of whole numbers up to 999.
2. Conduct a quick formative assessment by asking a few students to demonstrate place value concepts on the whiteboard.
Homework:
Ask students to complete a short assignment where they identify and write 10 different whole numbers between 1 and 999 and break each down into units, tens, and hundreds.
Reflection:
After the lesson, note which students were able to grasp the concepts easily and which might need more support. Plan to provide additional resources or targeted support during the next lesson if necessary.
