**TOPIC – ORDERING WHOLE NUMBERS WITH THE SYMBOLS **

**LEARNING AREA**

1. Introductory Activities

3. Weekly Assessment

**PERFORMANCE OBJECTIVES **

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. order whole numbers and use the symbols <, > and =.

2. mention the need for counting and ordering.

**ENTRY BEHAVIOUR **

Counting and Writing of Whole Numbers

**INSTRUCTIONAL MATERIALS**

The teacher will teach the lesson with the aid of:

1. Inequality chart

2. Elbow sign.

**METHOD OF TEACHING – Choose a suitable and appropriate methods for the lessons.**

**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 ExamplesTeacher’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

Solutions1. 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 THREE AND FOUR DIGIT NUMBERSTeacher’s/Pupil’s Activities – Guides the pupils to use the symbols <, > and = for 3 and 4 digit numbers.

For examples,

1. 487 and 489

2. 9 964 and 9 946

Solution 1

~~4~~~~8~~7

~~4~~~~8~~9From the left, compare each digit to the right by crossing the same value digit.

7 < 9

Therefore, 487 < 489.

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

~~9~~~~9~~6 4

~~9~~~~9~~4 66 > 4

Therefore, 9 964 > 9 946.

**LESSON EVALUATION/ASSIGNMENT **

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

1. 351 and 345

2. 513 and 543

3. 9 989 and 9 979

4. 427 and 447

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.

**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.
