Guidelines for solving Grade 4 Math on pages 160, 161, reviewing natural numbers (Including solving methods)

1. Solve Grade 4 Math on pages 160, 161, exercise 1 from the textbook

Problem Statement::

Write following the pattern:

Solving Method:

- To read and write natural numbers, read and write the digits from the highest to the lowest place value or from left to right.

Answer:

2. Solve Grade 4 Math on pages 160, 161, exercise 2 from the textbook

Problem Statement::

Write each number as a sum (following the example):

1763; 5794; 20,292; 190,909.

Example: 1763 = 1000 + 700 + 60 + 3.

Solving Method:

- Determine which place value each digit belongs to and then write them as a sum.

Answer:

5794 = 5000 + 700 + 90 + 4

20,292 = 20,000 + 200 + 92 + 2

190,909 = 100,000 + 90,000 + 900 + 9

3. Solve Grade 4 Math review exercises on natural numbers, pages 160-161, exercise 3 from the textbook

Problem Statement::

a) Read the following numbers and specify the place and class of the digit 5 in each number:

76,558; 851,904; 3,205,700; 195,080,126.

b) State the value of each digit 3 in the following numbers:

103; 1379; 8932; 13,064; 3,265,910.

Solving Method:

- To read natural numbers, start reading from the highest place value to the lowest (or read from left to right)

- To determine the digit (x) belonging to which place, students need to grasp:

+ Classes of digits in the ones place include: ones, tens, hundreds

+ Classes of numbers in the thousands place include: thousands, tens of thousands, hundreds of thousands

+ Classes of numbers in the millions place include: millions, tens of millions, hundreds of millions

Answer:

a) How to read the number 67,358: Sixty-seven thousand three hundred fifty-eight

In the number 67,358, the digit 5 belongs to the tens and ones places

- How to read the number 851,904: Eight hundred fifty-one thousand nine hundred four

In the number 851,904, the digit 5 belongs to the tens of thousands and thousands places

- How to read the number 3,205,700: Three million two hundred five thousand seven hundred

In the number 3,205,700, the digit 5 belongs to the thousands and units places

- How to read the number 195,080,126: One hundred ninety-five million eighty thousand one hundred twenty-six

In the number 195,080,126, the digit 5 belongs to the millions and units places

b) The digit 3 in the number 103 represents only 3 units.

- The digit 3 in the number 1379 represents only 3 hundreds.

- The digit 3 in the number 8932 represents only 3 tens.

- The digit 3 in the number 13,063 represents only 3 thousands.

- The digit 3 in the number 32,65,910 represents only 3 millions.

4. Solving 4th-grade math review exercises on natural numbers, pages 160-161, exercise 4 from the textbook

Problem Statement::

a) In a sequence of natural numbers, how many units apart are two consecutive natural numbers (greater or less) than each other?

b) What is the smallest natural number?

c) Is there a largest natural number? Why or why not?

Solving Method:

- Apply the knowledge learned about natural numbers to solve exercises.

Answer:

a) In a sequence of natural numbers, two consecutive natural numbers are always 1 unit apart.

b) The smallest natural number is 0.

c) There is no largest natural number. As no matter how large a natural number is, adding 1 to it will always result in a larger number.

5. Solve 4th-grade math review exercises on natural numbers, pages 160-161, exercise 5 from the textbook

Problem Statement:

Insert suitable numbers in the blanks to obtain:

a) Three consecutive natural numbers:

67; 68; 69

798; 799; 800

999; 1000; 1001

b) Three consecutive even numbers:

8; 10; 12

98; 100; 102

999; 1000; 1002

c) Three consecutive odd numbers:

51; 53; 55

199; 201; 203

998; 999; 1001

Solution:

- Apply the knowledge of consecutive numbers, consecutive even numbers, consecutive odd numbers to solve the exercise

Answer:

a) 67; 68; 69

798; 799; 800

999; 1000; 1001

b) 8; 10; 12

98; 100; 102

998; 1000; 1002

c) 51; 53; 55

199; 201; 203

997; 999; 1001

Additional note:

a) Two consecutive natural numbers differ by 1.

b) Two consecutive natural numbers differ by (or less than) 2 units.

c) Two consecutive odd numbers differ by (or less than) 2 units.

Frequently Asked Questions

What are the methods for solving Grade 4 math exercises on natural numbers?

To solve Grade 4 math exercises on natural numbers, students should read the digits from the highest to the lowest place value and follow specific methods for writing and summing natural numbers accurately.

How can students identify even and odd natural numbers in exercises?

Students can identify even numbers as those divisible by 2 and odd numbers as those that are not. This understanding is crucial for correctly solving exercises involving even and odd natural numbers.

Is there a largest natural number according to mathematical principles?

No, there is no largest natural number. Natural numbers continue indefinitely, so no matter how large a number is, adding one will always yield a larger number.

What is the smallest natural number, and how is it defined?

The smallest natural number is considered to be 0, although some definitions start from 1. Natural numbers include all positive integers and, in some contexts, 0 as well.

How do students write natural numbers as sums in Grade 4 exercises?

Students can write natural numbers as sums by determining the place value of each digit and expressing them accordingly. For example, 1763 can be written as 1000 + 700 + 60 + 3.
