CONTENT OF THE LESSON

LESSON ONE – INTRODUCTORY ACTIVITIES

COUNTING OF NUMBERS UP TO 500

Teacher’s/Pupil’s Activities 1 – Group the pupils into a certain number that will accommodate counting up to 999.

Guides pupils to prepare piles or bundles in hundreds or 200 depending on the number of groups up to 999 as shown below –

IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII

IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII

IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII IIIIIIIIII

Teacher’s/Pupil’s Activities 2 – Guides pupils to count together each item of the bundle.

Teacher’s Activities – Ensures that all the pupils participate in counting correctly numbers up to 500 correctly. Introduce the lesson and counting the counting from 500 to 999 in the next lesson.

LESSON EVALUATION/ASSIGNMENT

Write numbers from one to 500.

LESSON TWO – COUNTING OF NUMBERS UP TO 999

Teacher’s/Pupil’s Activities – Guides the to continue the activities in lesson from 500 to 999.

LESSON EVALUATION/ASSIGNMENT

Write numbers from 501 to 999.

LESSON THREE – IDENTIFICATION OF NUMBERS UP 999

Teacher’s/Pupil’s Activities 1 – Based on the previous lesson evaluations, asks each pupil to identify two or more numbers call for identification.

Teacher’s/Pupil’s Activities 2 – Prepares a number chart or flash card number, point to two or more numbers for each pupil to read correctly.

LESSON EVALUATION/EVALUATION

Numbers Dictation – Dictate 10 to 20 numbers from 200 to 999.

LESSON FOUR – PLACE VALUES OF NUMBERS UP TO 999 (5 minutes)

Teacher’s/Pupil’s Activities – 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 (10 minutes)

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 left to right 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
