WEEK 2
TOPIC: PLACE VALUE
BEHAVIORAL OBJECTIVES: FIRST TERM Pupils should be able to:
(i). Give the value of a digit in a Whole number e.g. the values of Each digit of the
number
(ii). State the value of each of the Digit in the decimal number given.
CONTENT
PLACE VALUE
1 is million
2 is hundred million
3 is ten million
4 is million
5 is hundred thousand
6 is ten thousand
7 is thousand
8 is hundred
9 is ten
0 is units
To find the value of a digit in a number, arrange the number in a table like the one
on
page 5. When you write down the digit, check to see under which group it belongs.
Then
you can write down the value.
Another way is to underline the digit and count how many numbers there are to the
right
of the digit. In place of those numbers you replace with zeros. For example,
looking at the
digits 7 and 5 in the number 235 678 140:
1 2 3 4 7 is followed by 4 zeros
1 2 3 4 5 6 5 is followed by 6 zeros
The digit 7 is followed by 4 zeros.
Therefore, the value of 7 in this number is 70 000.
The digit 5 is followed by 6 zeros.
Therefore, the value of 5 in this number is 5 000 000.
Exercise 1
In each box, write the corresponding digit for each place value.
1. 4 822 124 ! hundreds 2. 55 907 013 ! thousands
3. 190 641 335 ! hundred thousands 4. 248 307 214 ! tens
5. 7 694 097 ! millions 6. 201 480 110 ! hundred thousands
7. 42 458 219 074 ! ten billions
Exercise 2

Writing numbers in words and figures
When you write numbers in words, follow these steps.
1. Put a space in the number, three digits from the right.
2. Treat each part like separate number.

WEEK 3
CHANGING FRACTION TO DECIMAL
BEHAVIORAL OBJECTIVES: At the end of the lesson, pupils should be able to:
� recognise the meaning of decimals
� identify the place value of decimals
� write decimals in words and figures
� compare and order decimals
� convert decimals to fractions and vice versa
� find the fraction of quantities.

Unit 1 Meaning of decimals (Revision)
A decimal fraction is a number that has two parts, a whole number and a fraction.
The two
parts are separated by a point known as the decimal point, for example, 73.251.
The digits
before the point represent whole numbers. The digits after the point represent
fractions. Both
parts make up a decimal fraction
