**CONTENT OF THE LESSON **** **

**LESSON ONE – INTRODUCTORY ACTIVITIES **

**REVISION ON PLACE VALUES OF NUMBERS UP TO 99**

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 0and they are all calledUNITnumbers.

**FORMING NUMBERS UP TO 99**

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 –

TenandUnitfrom right to left.

Introduces

PLACE VALUES OF NUMBERSand 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

**LESSON EVALUATION/CLASS WORK/ASSIGNMENT **

Find the place values of the following numbers –

1. 54

2. 23

3. 90

4. 79

**LESSON TWO – PLACE VALUES OF NUMBERS UP TO 200 **

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

For example, 123 – 108, etc.

Teacher’s remark – Each of the number has three values –

Hundred–Ten–Unitfrom right to left and guide the pupils identify the place value of each digit of the numbers as shown below –

1 2 3

1 Hundred 2 Ten 2 UnitOR

H T U

1 2 3Therefore, the value of –

- 1 is hundreds

- 2 is tens

- 3 is units

Teacher’s activities – Takes one more example.

**LESSON EVALUATION/ASSIGNMENT/MARKING/CORRECTION **

Find the place value of 3 in the following numbers –

1. 154

2. 143

3. 100

Find the place value of 1 in the following numbers –

4. 109

5. 200

6. 199

**LESSON THREE – PLACE VALUES OF WHOLE NUMBERS UP TO 200**

Teacher’s/Pupil’s Activities 4 – Continuation of place values up to 200. More example and also consider quick assessment for the pupils.

**LESSON EVALUATION/CLASS WORK/ASSIGNMENT **

1. 50

2. 167

3. 69

4. 200

**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 write a given whole number.

Pupil’s Activities – Write 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.

**LESSON EVALUATION **

**Pupils to:**

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

2. write any given whole numbers.
