**Lesson Plan for Mathematics: Ordering of Whole Numbers and Using Symbols (<, >, =)**
**Grade Level:** Primary 4
**Duration:** 60 minutes
**Topic:**
(a) Ordering of Whole Numbers with Symbols up to 100,000
(b) Understanding and Using <, >, = (greater than, less than, equal to)
---
### **Objectives:**
1. **Knowledge:** Students will understand how to order whole numbers up to 100,000.
2. **Skills:** Students will be able to use comparative symbols (<, >, =) accurately.
3. **Reasoning:** Students will develop quantitative reasoning for comparing and ordering numbers.
### **Materials Needed:**
- Whiteboard and markers
- Number cards ranging up to 100,000
- Interactive number line (drawn on the whiteboard or projected)
- Worksheets on ordering numbers
- Flashcards with <, >, and = symbols
- Sample exercises for group activities
### **Lesson Outline:**
1. **Introduction (10 minutes):**
- **Engage Students:** Begin with a quick recap of numbers up to 10,000. Ask students to list some large numbers they know and write them on the board.
- **Introduce the Topic:** Explain that today they will learn how to order larger numbers up to 100,000 and use symbols to compare them.
2. **Direct Instruction (15 minutes):**
- **Explain Ordering:** Show students how to compare and order numbers by looking at each digit from left to right, starting with the highest place value (ten-thousands, thousands, hundreds, tens, and ones).
- **Use Examples:** Write examples of numbers on the board and demonstrate the ordering process.
- Example: Ordering 76,123, 23,456, 97,654, and 45,678.
- **Introduce Symbols:** Explain what each symbol (<, >, =) means and how they are used to compare two numbers.
- `<` means "less than"
- `>` means "greater than"
- `=` means "equal to"
3. **Guided Practice (15 minutes):**
- **Interactive Number Line:** Use a projected or drawn number line to visually place numbers up to 100,000.
- **Group Activity:** Divide students into small groups and give each group a set of number cards and flashcards with symbols. Ask them to order the numbers and use the correct symbols between each pair.
- **Walk Around:** Monitor groups and provide assistance where needed.
4. **Independent Practice (10 minutes):**
- **Worksheet Activity:** Hand out worksheets with exercises requiring students to order sets of numbers and use symbols to compare pairs of numbers.
- Example Task:
- Order the following numbers: 87,245; 32,678; 98,123; 65,490.
- Compare the following numbers using <, >, or =: 45,678 and 54,876.
5. **Review and Reinforcement (5 minutes):**
- **Quick Review Game:** Use a quickfire round where students raise their hands to answer questions on number ordering or the correct use of <, >, and = symbols based on given examples.
6. **Assessment and Closure (5 minutes):**
- **Exit Ticket:** Give students a quick exit ticket with 2-3 questions to assess their understanding of ordering numbers and using comparison symbols.
- Example Exit Ticket Question:
- Compare: 76,543 ___ 76,453
- Order from least to greatest: 91,234; 20,456; 67,890
7. **Homework Assignment:**
- **Home Practice:** Provide homework sheets for further practice on ordering numbers and comparing them using symbols. Encourage students to explain their reasoning to an adult at home.
### **Reflection:**
- After the lesson, reflect on the students' engagement and understanding. Note which areas were challenging and consider revisiting those in future lessons.
- Collect and review the exit tickets to gauge individual student's comprehension and identify those who might need additional support.

By the end of the lesson, students should be able to confidently order numbers up to 100,000 and use the <, >, and = symbols to make comparisons, demonstrating their quantitative reasoning skills.
