3. Jasmine Monsad

6. MATHEMATICS 4
Teacher Nathalie C. Peña

8. LESSON 3: COMPARING AND ORDERING
Objectives:
In this unit, students compare and order two-digit numbers. Students
will:
• use the symbols <, >, or = to compare numbers.
• read the number sentence with symbol aloud.
• order numbers from least to greatest.
• order numbers from greatest to least.

9. When comparing numbers, compare the digits in each
place value. Always start with the highest place value.
Means “greater than”
Means “less than”
Means “equal to”

10. Let’s Compare…
23 678 25 678
same
3 < 5
23 678 < 25 678
23 678 is “less than”
25 678

11. Let’s Compare…
2 457 531 2 456 563
same
same
same
7 > 6
2 457 531 > 2 456 563

12. Let’s Say…
34 456 210 34 456 210
34 456 210 is “equal to”
34 456 210

13. Let’s Try…
• Compare by using > , < or =.
1) 3 321 ______ 3221
>
2) 572 481 ______ 572 481
=
3) 26 287 051 _______ 23 287 352
>

14. Lesson 4: ROUNDING NUMBERS
Objectives:
After this lesson, students will be able to:
• Dictate the rules of rounding numbers.
• Round numbers to the nearest millions.

15. To round off numbers:
1. Underline the digit in the rounding place.
2. Look at the digit to its right.
a. If the digit is less than 5, copy the underlined digit.
b. If the digit is 5 or more, add 1 to the underlined digit.
3. Change all digits to the right of the underlined digit to zeros.

16. Let’s Say…
564 988 is to be rounded to the nearest thousands. What will it be?
Underline the digit in the rounding place.
564 988

17. Look the digit to its right.
564 988
a. If the digit is less
than 5, copy the
underlined digit.
b. If the digit is 5 or
more, add 1 to the
underlined digit.
565 000
Change all digits to the
right of the underlined
digit to zeros.

18. Let’s Say…
3 256 291 is to be rounded off to its highest place value.
3 256 291
The digit to
the right is 2.
Since the digit to the
right is less than 5,
add 1 to the
underlined digit:
3 + 1 = 4
4 000 000

19. Let’s Try…
• Round to the nearest tens.
1. 4 532
• Round to the nearest ten thousands.
2) 346 654
• Round to the nearest millions.
3) 23 576 862
4 430
350 000
24 000 000

22. A. Compare by using > , < or =.
1) 34 139 _____ 34 168
2) 132 580 _____ 13 258
3) 476 210 _____ 476 210
4) 5 768 224 _____ 5 768 124
5) 243 760 _____ 2 437 600

23. • Round off each number to the place of the underlined
digit.
1) 5 531
2) 38 821
3) 955 100
4) 548 658
5) 993 213

24. 1. Answer pages 6 and 10 on
your book.
