CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTORY ACTIVITIES 

Teacher’s/Pupil’s Activities – Asks the pupils to arrange the these numbers from the lowest to the highest – 25, 20, 41, 78, 15 and 5.

Pupil’s Activities – 5, 15, 20, 25, 41 and 78.

Asks them to compare (greater or less than) the pair of numbers –

• 15 and 10

• 41 and 43

Pupil’s Expected Response – 15 is greater than 10 and 41 is less than 43.

ORDERING WHOLE NUMBERS WITH THE SYMBOLS <, > AND = 

Teacher’s Activities – Displays three flash cards showing <, > and = symbols (signs) for the pupils to identify.

<          greater than

>          less than

=          equal to.

Teacher’s/Pupil’s Activities – Guides the pupils to use <, > and = symbols to order above numbers compared –

• 15 and 10

• 41 and 43

15 is greater than 10        ⇒       15 > 10

41 is less than 43              ⇒       41 < 43

 

Further Working Examples 

Teacher’s/Pupil’s Activities – Guides the pupils to ordering the following numbers using – <, > and = symbols

1. 5 + 2 and 4 + 3

2. 10 + 1 and 5 + 7

3. 15 – 4 and 25 – 19

 

Solutions

1. 5 + 2 and 4 + 3

IIIII + II and IIII + III, allow counting for simplicity.

7 and 7

Therefore, 7 = 7

 

2. 10 + 1 and 5 + 7

11 and 12

Therefore, 11 < 12

 

3. 15 – 4 and 25 – 19

11 and 6

Therefore, 11 > 6

LESSON EVALUATION/ASSIGNMENT 

Use the correct symbol <, > or =, to complete the following.

1. 56 _______ 45

2. 27 _______ 90

3. 23 – 5 _______ 15 + 4

4. 15 + 6 _______ 18 – 0

LESSON TWO – ORDERING WHOLE NUMBERS WITH THE SYMBOLS <, > AND =

ORDERING OF NUMBERS UP 200

Teacher’s/Pupil’s Activities – Guides the pupils to use the symbols <, > and = for 3 and 4 digit numbers.

For examples,

1. 187 and 189

2. 164 and 146

 

Solution 1

1 8 7

1 8 9

From the left, compare each digit to the right by crossing the same value digit.

7 < 9

Therefore, 187 < 189.

Or

If the first two or three digits are the same, compare the next to determine the value of the numbers.

For example, the first two digits are the same except for the last digits – 7 and 9.

Solution 2

1 9 4

1 9 6

6 > 4

Therefore, 196 > 194.

 

LESSON EVALUATION/ASSIGNMENT 

Use the correct symbol <, > or =, to complete the following.

1. 151 and 145

2. 113 and 143

3. 189 and 198

4. 172 and 127

5. 4 – 2 + 7 and 4 + 4 – 7

 

LESSON THREE – REPEAT THE ACTIVITIES LESSON TWO 

LESSON FOUR – WEEKLY ASSESSMENT 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Compare the given numbers using symbols of <, > and =.

3. Mention the need for counting and ordering in everyday activities.

Pul Activities – Order pairs of 3-digit numbers using <, > and = symbols.

CONCLUSION

• To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

• Next Lesson – Fractions – 1/2 and 1/4 of a given Collection Objects (Primary 2)

LESSON EVALUATION 

Pupils to:

1. state the place value of a digit in a given whole number.

2. order pairs of 3-digit numbers using < and > symbols.
