### LESSON 1 – INTRODUCTORY ACTIVITIES

Counting numbers are also called whole numbers.

These are the set or pattern of numbers.

They are natural or positive numbers that we use to learn how to count. 1, 2, 3, 4, 5, and so on.

ACTIVITY 2

REVISION OF READING AND WRITING UP TO ONE MILLION IN WORDS

Use the below format to guide pupils to read and write whole numbers:

MILLIONS          THOUSANDS           HUNDREDS

H    T    U                H    T    U                 H    T    U

0    0    0                  0    0    0                  0    0    0

WORKING EXAMPLES

Guide pupils to read and write the following correctly in words:

1. 4 962

MILLIONS          THOUSANDS           HUNDREDS

H    T    U                H    T    U                 H    T    U

0    0    0                  0     0   4                  9    6    2

Correct

Four thousands, nine hundreds sixty-two.

Incorrect

Four thousands, nine hundreds and sixty-two.

2. 71 305

MILLIONS          THOUSANDS           HUNDREDS

H    T    U                H    T    U                 H    T    U

0    0    0                 0    7    1                  3    0    5

Correct

Seventy-one thousands, three hundreds and two.

Incorrect

Seventy-one thousands, three hundreds and two.

QUICK EVALUATION 2

Write in words or figures:

1. 2 794

2. 25 371

3. One thousands, three hundreds sixty-one.

4. Six-five thousands, nine hundreds and two.

SOLUTIONS

1. 2 794

Two thousands, seven hundreds ninety-four.

2. 25 071

Twenty -five thousands, and seventy-one.

3. 1 361

Hint,

1  – one

60 + 1 – sixty-one

300 + 61 – three hundred sixty-one

1 000 + 361 – one thousand, three hundred sixty-one

Therefore, 1 361 is One thousands, three hundreds sixty-one.

QUICKEST WAYS OF WRITING IN FIGURES

Instructions:

• Cancel the billion, thousands and hundreds
• Replace and with 1 zero, if the number is in ten or 2 zeros (or more) if it is in unit.
• For example, and 51 is 051 while and five is 005 or 21 million and 2 – 21 000 002
• Replace words with exact figures.
• Let the commas ( , ) remain.

Example – One thousands, three hundreds sixty-one.

1 thousands, 3 hundreds 61.

1 361

4. 65 thousands, 9 hundreds 0 2.

65 902

### LESSON 2 – READING AND WRITING IN MILLIONS WORDS

ACTIVITY 1

We read and write in millions when there are more than six (6) digits in a number.

When writing whole numbers in million, it is very important to group the digits from the rightmost in threes (3s) if it is not not or separated by comma ( , ).

Each group of three can be separated by comma or space. The grouping will help you to read and write.

For example, the first group in hundreds, follow by thousands and last is in million.

That’s,

MILLIONS          THOUSANDS           HUNDREDS

H    T    U                H    T    U                 H    T    U

1     0     0                0    0    0                  0    0    0

ACTIVITY 2

READING AND WRITING WHOLE NUMBERS IN WORDS

Guide pupils to group in 3s, read and write:

Example 1. 7347840 – 7,347,840 or 347 840

MILLIONS    THOUSANDS    HUNDREDS

H   T   U           H   T   U             H   T   U

0   0   7            3    4   7              8   4   0

Guide pupils to read and write.

• 7 millions
• Three hundred forty-seven thousands,
• Eight hundred forty.

Read loud and clear Three hundred forty-seven thousand, eight hundred forty.

Example 2. 85048602 – 85,048,602 or 85 045 602

MILLIONS    THOUSANDS    HUNDREDS

H   T   U           H   T   U             H   T   U

0    8   5            0    4   8             6    0   2

Guide in words –

• 85 millions – Eighty-five million,
• 48 thousands – And forty-eight thousand,
• 602 – Six hundred and two

Read loud and clear – Eighty-five million, and forty eight thousand, six hundred and two.

Example 3. 736495127

736 495 127

MILLIONS    THOUSANDS    HUNDREDS

H   T   U           H   T   U             H   T   U

7    3   6            4    9   5            1    2   7

Guide to read and write in words –

736 millions – Seven hundred thirty-six million,

595 thousands – five hundred ninety-five thousand,

127 – one hundred twenty-seven.

Read loud and clear – Seven hundred thirty-six million, five hundred ninety-five thousand, one hundred twenty-seven.

CLASS WORK

Write the following in words:

1. 22 018 736

2. 495 127 685

3. 390 617 320

4. 594 840

### LESSON 3 – READING AND WRITING WHOLE IN FIGURE

ACTIVITY 3

READING AND WRITING WHOLE IN FIGURE

The minimum digits for million is seven (7) while maximum is nine (9). Million is in three (3) categories –

• The unit million has seven digit number.
• The ten million has 8 digit number.
• The hundred billions has 9 digit number.

Guide pupils to read and write:

Example 1.

Seventy-five million, five hundred ten.

Seventy five million – 75 million (75 + 6 zero) = 75 000 000

Five hundred ten – (500 + 10) hundred = 510

75 000 000

500

+               10

_____________

75 000 510

2. Eight hundred twenty-two million, one hundred thirty-one thousand, five hundred and eight.

Eight hundred twenty-two million – (800 + 22) million = 822 + 6 zeros = 822 000 000

One hundred thirty-one thousand – (100 + 31) thousands  = 131 thousands – 131 000

Five hundred eight – (500 + 8) = 508

822 000 000

131 000

+              508

_____________

822 131 508

OR

8 hundred 22 million, 1 hundred 31 thousand, 5 hundred 0 8

822 131 508

CLASS WORK

Write in words and figures:

1. Two hundred seventy-four million, nine hundred three thousand, two hundred eighty.

2. Three hundred ten million, five hundred seventy thousand, six hundred ninety-one.

3. Two hundred million, ten thousand and thirty.

4. Nine hundred five million, three hundred sixty thousand, six hundred ninety-one.
