1. Presentation
Problem:
Every morning Atty. Arcigalreads the newspaper. He takes note of the dollar
exchange. One morning, he read that the exchange rate of a dollar is P 46.468. How
does we read this number?
Present the decimal number in a place value chart.
Let’s use the place value chart to help you read the number.
Using the chart the pupils will read the given decimal, then write it also in words as:
forty-six and four hundred sixty-eight thousandths.
46.468 is a decimal number in standard form. It is read as “forty-six and four hundred
sixty-eight thousandths”.
C. Presentation
Read each number in the chart below.
Like whole numbers, we read decimals from left to right. The digits to the left of the decimal
point are read as a whole number, and the decimal point is read as “and”. The digits to the
right of the point are also read as a whole number, after which we say the name of the place
value of the digit.

2 2 1 7
The numbers in the chart are read as follows:
1.9876 – Nine and nine thousand eight hundred seventy-six ten thousands
221.7 – two hundred twenty one and seven tenths
a. Flash cards one at a time. Let the pupil read and write decimal numbers.
1. 7-tenths 2. 3-tens
2-hundredths 6-ones
4-thousandths 5- tenths
5-ten thousandths8- hundredths 9-ten thousandths
b. Have pupils work in pairs. Each pair works on every station simultaneously. Each
of them will check their answers and present their output.
Station 1. Write five and three hundred ten thousandths in decimal form.
Station 2. Write 24 and 6 hundred ten thousandths in decimal form. Then write
in
words.
Station 3. Write 46 and sixty-three hundredths in decimal form. Then write in
words
Station 4. Write 92 ten thousandths in decimal form and write in words.
Station 5. Write four thousand fifteen and forty-one thousandths in decimal.
F. Developing Mastery
Like whole numbers, we read decimals from left to right. The digits to
the left of the decimal point are read as a whole number, and the
decimal point is read as “and”. The digits to the right of the point are
also read as a whole number, after which we say the name of the place
value of the digit.
IV. Evaluation
Read then write the following decimals in words and in standard form. Give what is
ask.
V. Home Activity

A. Encourage the pupils to work in pairs. Give them time to solve for
the answer to the problem by illustration.
0. 3 2 5
Round off place ( hundredths digit)
23. 7 4 2 6
Round off place ( thousandths digit)
To round a decimal number, determine first the rounding place. Then look at the digit
to the right of the rounding place. The digit in the rounding place is the one that will
either be rounded up or rounded down depending on the digit to its right. If it is 5 or
greater, add 1 to the rounding place. If it is less than 5, retain the digit in the rounding
place. Do not forget to drop all the digits after the rounding place.
1. Have the pupils play by pair. The pair that gets the most number of correct
answers wins.
1. Flash cards one at a time. Let the pupils round to nearest hundredths.
6.540 7.346 0.3892 0.0452 75.3460
2.Flash the cards one at a time. Let the pupils round to the nearest thousandths.
6.34571 22.78649 12.40935 6.1469 32.3487
After the group have played, ask,” How do you find the activity? How did you
round decimal number nearest to hundredths and thousandths?”
Expected answer:
By following the rules in rounding off numbers.

1. Joshua and Marcus are playing a number game. They try to round 213.432
to the nearest hundredths. What is the answer?
Rina was task to round off 85.81267 to the nearest hundredths. Her answer
was 85.800. Is she correct? Why?
Earth travels around the sun at a speed of about 29.783 km. per second.
Round this number to the nearest tenths.
Mario has toy weights 54. 7827. Round it to the nearest thousandths.
To round a decimal number, determine first the rounding place. Then look at the digit
to the right of the rounding place. The digit in the rounding place is the one that will
either be rounded up or rounded down depending on the digit to its right. If it is 5 or
greater, add 1 to the rounding place. If it is less than 5, retain the digit in the rounding
