Ordering Of Numbers Using Symbols Basic 2 Mathematics Lesson Note

Learning Objectives

By the end of this week, pupils should be able to:

• Count and identify numbers from 1-350
• Write numbers 1-350 in numerals and words
• Understand and use comparison symbols: <, >, =
• Compare numbers within 0-350
• Order numbers from smallest to largest and vice versa

Lesson Content

Day 1: Counting to 350

New Number Range:

• Practice counting from 1-350
• Focus on numbers 320-350
• Learn to read: 321, 322, 323… 350
• Write these numbers neatly

Day 2-3: Comparison Symbols

Learning the Symbols:

Greater Than (>):

• Means “bigger than” or “more than”
• The big mouth opens to the bigger number
• Example: 5 > 2 (5 is greater than 2)

Less Than (<):

• Means “smaller than” or “fewer than”
• The small point points to the smaller number
• Example: 3 < 7 (3 is less than 7)

Equal To (=):

• Means “the same as”
• Both sides have the same value
• Example: 5 = 5 or 2 + 3 = 5

Memory Trick: Think of the symbols as a hungry alligator – it always wants to eat the bigger number!

Day 4: Comparing Numbers

How to Compare:

1. Look at the hundreds first
2. If hundreds are the same, look at tens
3. If tens are the same, look at units

Examples:

• 245 > 234 (because 4 tens > 3 tens)
• 156 < 165 (because 5 tens < 6 tens)
• 200 = 200 (exactly the same)

Day 5: Ordering Numbers

Arranging Numbers:

• Ascending order: From smallest to largest (1, 2, 3, 4…)
• Descending order: From largest to smallest (10, 9, 8, 7…)

Example: Order these numbers: 145, 89, 234, 156

• Ascending: 89, 145, 156, 234
• Descending: 234, 156, 145, 89

Examples in Class

Comparison Examples:

Example 1: Compare 156 and 145

• Look at hundreds: 1 = 1 (same)
• Look at tens: 5 > 4
• So: 156 > 145

Example 2: Compare 89 and 134

• Look at hundreds: 0 < 1
• So: 89 < 134

Real-Life Examples:

• “Tom has 45 marbles, Jane has 52 marbles. Who has more?” 45 < 52, so Jane has more marbles. 
• “Class A has 125 books, Class B has 125 books. Do they have the same number?” 125 = 125, yes they have the same number. 

Ordering Example:

“Heights of children: Ann (145cm), Ben (134cm), Carl (156cm), Dana (142cm)”

• Shortest to tallest: Ben (134), Dana (142), Ann (145), Carl (156)
• Tallest to shortest: Carl (156), Ann (145), Dana (142), Ben (134)

Exercises

Exercise 1: Symbol Recognition

Fill in the correct symbol (>, <, or =):

1. 145 ___ 154
2. 89 ___ 89
3. 234 ___ 189
4. 67 ___ 76
5. 200 ___ 150

Exercise 2: Comparing Numbers

Compare these numbers using >, <, or =:

1. 156 ___ 165
2. 234 ___ 234
3. 89 ___ 98
4. 345 ___ 354
5. 278 ___ 287

Exercise 3: True or False

1. 145 > 154 (True/False)
2. 89 = 89 (True/False)
3. 200 < 150 (True/False)
4. 67 > 76 (True/False)

Exercise 4: Ordering Numbers

Arrange in ascending order (smallest to largest):

1. 145, 89, 234, 156: _______________
2. 67, 234, 12, 189: _______________

Arrange in descending order (largest to smallest): 3. 145, 89, 234, 156: _______________ 4. 298, 156, 67, 203: _______________

Exercise 5: Word Problems

1. School A has 245 pupils, School B has 254 pupils. Which school has more pupils? 
2. Mary scored 89 marks, John scored 98 marks, and Peter scored 89 marks. Who scored the highest? Who scored the same as Mary? 
3. Arrange these distances in order from shortest to longest: 156m, 89m, 234m, 145m. 

Exercise 6: Fill in the Missing Numbers

1. 89 < ___ < 91
2. 145 > ___ > 143
3. ___ = 156 = ___

Fun Activities

• Number Race: Hold up number cards and students compare them quickly
• Human Number Line: Students arrange themselves in order by their numbers
• Greater Than/Less Than Game: Use body movements to show symbols

Homework

• Compare 10 pairs of numbers using the correct symbols
• Order your family members by age (ascending and descending)
• Find numbers around your home and arrange them in order

Assessment

• Can the child use >, <, and = symbols correctly?
• Do they understand how to compare three-digit numbers?
• Can they order numbers in ascending and descending order?
• Can they apply comparison skills to solve real-life problems?
• Do they remember the memory tricks for the symbols?
