FIRST TERM

FIRST WEEK

BASIC 6

TOPIC: Whole Numbers – Reading and Writing Up To One Million

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.

PERFORMANCE OBJECTIVES
• By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor):
1. count in millions and billions;
2. write and read up to one million;
3. solve problems involving quantitative reasoning.
ENTRY BEHAVIOR
• The pupils are required to already have learnt…

INSTRUCTIONAL MATERIALS

• The teacher will teach the lesson with the aid of abacus and charts of numbers etc.

METHOD OF TEACHING

1. Inductive – Deductive
2. Problem Solving
3. Discovery/Inquiry
REFERENCE MATERIALS
1. New Method Mathematics book 6
2. Prime Mathematics
3. Primary Mathematics
4. MacMillan New Primary Mathematics
5. All Relevant materials

CONTENT OF THE LESSON
• COUNTING IN MILLIONS AND BILLIONS
We count in millions when there are more than six digits in a number.
For example
Study the sequence below:
• 1,000,000  2,000,000  3,000,000  4,000,000 . . . 999,000,000
• 2,000,000  4,000,000  6,000,000  8,000,000 . . . 888,000,000
• #2,500,000  #5,000,000  #7,500,000  #10,000,000 . . .
• \$5,000,100  \$5,000,200  #5,000,300  #5,000,400 . . .
Further illustrations
Study the pattern and write the missing numbers in the spaces provided:
1. 1,455,500  1,555,600   ___   ___   ___   2,056,100   2,156,200  (hint – 100,100)
2. 2,203,456  2,302,654   ___   2,501,050  ___  ___   2,798,446  (hint – 99,198)
3. 5,555,555  ___   3,333,333   ___   1,111,111   ___  (hint – 1,111,111)
• READ AND WRITE UP TO ONE MILLION
Example 1
1. 347840
2. 85048602
Hint – when reading or writing in numerals, it is very important to group them in 3s (especially when numbers are more than three digits, starting from the unit digits, then read from the left) so that it will be easy to place them under billions, millions, thousands, hundreds  tens and units.

Each group of three can be separated by comma or space.

• 347840
Group – 347,840 or 347 840
Place,
MILLIONS    THOUSANDS    HUNDREDS
H   T   U           H   T   U             H   T   U
3    4   7              8   4   0

Three Hundred and forty seven Thousand, eight Hundred and forty.

• 85048602
Group – 85,048,602 or 85 045 602

Place,

MILLIONS    THOUSANDS    HUNDREDS

H   T   U           H   T   U             H   T   U

Eighty five Million, and forty eight Thousand, six Hundred and two.
Further illustrations
1. 1,000 x 1,000 =
2. 1,006,342 + 2,002,258 =
3. 4,692,250 x 4 =
4. 83,687,640 – 19,670,046 =
Write these in figures:
1. Seventy five million, five hundred and ten.
2. Twenty two million, five hundred and eight.
Write these in words:
1. 1,444,444,444
2. 6,999,086
• QUANTITATIVE REASONING
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 the pupils to revise the previous work in counting up to counting in millions;
3. Pupil’s Activities – Revise counting up to one million;
4. Guides pupils to count in millions up to nine hundred millions;
5. Pupil’s Activities – Count in millions up to nine hundred million.
6. Guides pupils to read up to one million as shown below;
7. Pupil’s Activities – Write numbers up to one million.
8. Devises other practices or methods to write and read up to one billion;
9. Pupil’s Activities – Devise other practices or methods to write and read up to one billion.
10. Guides pupils to solve problems in quantitative reasoning;
11. Pupil’s Activities – Solve problems in quantitative reasoning.
