**CONTENT OF THE LESSON**

**ORDERING OF WHOLE NUMBERS UP TO 1000**

Arrange these numbers in order of sizes, largest first:

- 43, 45, 42, 41
- 243, 443, 143, 340
- 676, 760, 776, 706
- 110, 101, 111, 10

**Solution 1**

43, 45, 42, 41

Largest first,

45, 43, 42, 41

**Solution 2**

243, 443, 143, 340

Largest first

443, 340, 243, 143 [click]

**USE OF GREATER THAN AND LESS THAN SYMBOLS IN ORDERING OF NUMBERS **

**GREATER THAN > L****ESS THAN <**

Copy and complete. Write > or < in the boxes provided.

- 15 [ ] 25
- 64 [ ] 52
- 34 [ ] 35
- 12 + 13 [ ] 21 + 12
- 12 – 5 [ ] 13 – 8

**Solution 1, 15 ¤ 25**

15 [ < ] 25

25 [ > ] 15

**Solution 4, 12 + 13 [ ] 21 + 12**

12 + 13 = 25

21 + 12 = 33

Therefore,

12 + 13 [ < ] 21 + 12

**QUANTITATIVE REASONING **

Copy and complete. Write > or < in the boxes provided, if A = 4, B = 2, C = 6, D = 8

- A + C [ ] A + B
- B + D [ ] D + C
- C + C [ ] A + A
- D + A [ ] C + B [click]

**PRESENTATION**

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

- To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
- Guides pupils in ordering of numbers 1 – 500 on numeral chart.
- Pupil’s Activities – Revises order of numbers 1 – 500 using number charts.
- Leads pupils to recall the meaning of the symbol (< and >).
- Pupil’s Activities – Recall the meaning of the symbol (< and >).
- Guide pupils to order two numbers;
- Pupil’s Activities – Order any two given numbers;
- Gives more exercises on ordering of whole numbers.
- Pupil’s Activities – Solve problems on ordering whole numbers.
- Guides pupils to solve some quantitative aptitude problems involving ordering of whole numbers.
- Pupil’s Activities – Solve problems on quantitative aptitude involving ordering of whole numbers.

**CONCLUSION**

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

**LESSON EVALUATION**

**Pupils to:**

- order given whole numbers;
- solve more problems on quantitative aptitude.
