CONTENT OF THE LESSON

LESSON ONE – INTRODUCTORY ACTIVITIES

REVISION ON PLACE VALUES OF NUMBERS UP TO 999

Teacher’s/Pupil’s Activities 1 – Displays a number chart of 0 – 9 for pupils to identify and read loudly.

Teacher’s remark – There are 10 symbols of numbers where other numbers are formed by adding one digit to another or repeating each digit.

These numbers are – 1   2   3   4   5   6   7   8   9   as well as 0 and they are all called UNIT numbers.

FORMING NUMBERS UP TO 3 DIGITS UP TO 999

Teacher’s Activities 2 – Prepare 20 flash card numbers from 0 – 9 and asks each each one by one (if it to pick to two digits and read out the number loudly.

Teacher’s remark – Each number formed has two values – Ten and Unit from right to left.

Introduces PLACE VALUES OF NUMBERS and asks the pupils to state the value of each number formed the two digits.

For example, 3 and 4, 2 and 0

1. 34 and 43 are form from 3 and 4.

Therefore, the value of 34 and 43 are –

• 34 – 3 Tens and 4 Units
• 43 – 4 Tens and 3 Units

2. 20 and 02 are formed from 2 and 0.

Therefore, the value of 20 and 02 are –

• 20 – 2 Tens and 0 Unit
• 02 – 0 Ten and 2 Units

PLACE VALUES OF NUMBERS UP TO 999 (10 minutes)

Teacher’s/Pupil’s Activities 3 – Asks six pupils to pick 3 digits to a number and read loudly to the class.

For example, 352 – 108 – 545, etc.

Teacher’s remark – Each of the number has three values – HundredTenUnit from right to left and guide the pupils identify the place value of each digit of the numbers as shown below –

3       5      2

3 Hundreds 5 Tens 2 Units

OR

H    T    U

3   5    2

Therefore, the value of –

• 3 is hundreds
• 5 is tens
• 2 is units

Teacher’s activities – Takes one more example.

LESSON EVALUATION/ASSIGNMENT/MARKING/CORRECTION (15 minutes)

Find the place value of 3 in the following numbers –

1. 321

2. 123

3. 231

Find the place value of 1 in the following numbers –

4. 312

5. 213

6. 132

LESSON TWO – PLACE VALUES OF WHOLE NUMBERS UP TO 9 999

Teacher’s/Pupil’s Activities 3 – Asks two pupils to pick 4 digits to form a number and read loudly to the class.

For example, 3052 – 1278 – 5495, etc.

Teacher’s remark – Each of the number has three values – Thousand – HundredTenUnit from right to left and guide the pupils identify the place value of each digit of the numbers as shown below –

3       0       5       2

3 Thousands 0 Hundreds 5 Tens 2 Units

OR

Th   H    T    U

3     0    5    2

Therefore, the value of –

• 3 Thousands
• 0 is hundreds
• 5 is tens
• 2 is units

Teacher’s activities – Takes one or more example and also consider quick assessment for the pupils.

LESSON THREE – EXPANSION OF WHOLE NUMBERS

Teacher’s/Pupil’s Activities 1 – From the flash card numbers, asks four pupils to pick a digit each to form a number and read loudly.

Assume the number formed is

## 4   2    5   3

Guided instructions –

1. Asks them to state the place values of each digit of the number.

3 Units

5 Tens

2 Hundreds

4 Thousands

2. Discuss with the pupils what each value stands for –

• Unit                       – 1
• Ten                        – 10
• Hundred               – 100
• Thousand            – 1 000

3. Leads them to expand 4 2 5 3 –

• 3 x 1               = 3
• 5 x 10             = 50
• 2 x 100          = 200
• 4 x 1 000       = 4 000

That’s, 4 2 5 3 = 4 000 + 200 + 50 + 3

4. Guides the pupils to do quick expansion.

For example, 1 0 2 6 = 1 000 + 000 + 20 + 6

LESSON EVALUATION/ASSIGNMENT

Expand the following numbers –

1. 5 003

2. 9 367

3. 6 890

4. 2 300

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. Guides pupils to find the place value of each digit in a number.

Pupil’s Activities – Identify the place of each digit in a number.

3. Guides pupils to expand a given whole number.

Pupil’s Activities – Expand any given whole numbers.

4. Weekly Assessment

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 –

LESSON EVALUATION

Pupils to:

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

2. expand any given whole numbers.
