Test: Thousands Around Us - Class 4 MCQ

The representation of 7 Thousand, 0 Hundreds, 2 Tens, and 4 Ones is 7024.

To understand how 10 hundreds equates to thousands:

• 1 hundred equals 100.
• Therefore, 10 hundreds equal 10 x 100.
• This results in 1000, which is equivalent to 1 thousand.

Thus, 10 hundreds is the same as 1 thousand.

Dienes Blocks are used to help learners understand numbers by providing a visual representation of different place values. They are beneficial in the following ways:

• Each block represents a specific quantity, such as 1 block for 1 One.
• They show how 10 Ones can be grouped into 1 Ten, simplifying the concept of grouping and regrouping numbers.
• These visual aids make it easier for students to grasp the fundamental concepts of number composition.

Comparing Numbers

• When comparing numbers, check digits from left to right.

• Here, 3102 is compared with 3012.

• The thousands digit of 3102 is 3, same as 3012.

• The hundreds digit of 3102 is 1, which is greater than the 0 in 3012.

• Therefore, 3102 is indeed greater than 3012.

• The face value of a digit is the actual value of the digit itself.
• In the number 2,859, the face value of the digit 5 is simply 5.
• The face value does not change with the position of the digit in the number.

The number 250 can be represented using place values as follows:

• 2 Hundreds
• 5 Tens
• 0 Ones

Tokens simplify the representation of larger numbers, with each token representing a specific quantity (e.g., 1000 tokens represent 1 Thousand).

The smallest four-digit number is 1000.

• Four-digit numbers start at 1000.
• Numbers like 0001 are considered one-digit numbers.

To determine the smallest number among a set of numbers, compare each digit from left to right:

• Thousands place: All numbers start with 3, so move to the next digit.
• Hundreds place: 3142 has the smallest value, 1, compared to others which have 2 or 4 (1 < 2 or 4).
• This makes 3142 the smallest number.

14 Ones can be grouped as:

• 1 Ten
• 4 Ones

Digit in the thousands place: 4, so value = 4 × 1000 = 4000
Digit in the hundreds place: 0, so value = 0 × 100 = 0
Digit in the tens place: 8, so value = 8 × 10 = 80
Digit in the ones place: 5, so value = 5 × 1 = 5

The expanded form is:
4000 + 0 + 80 + 5

Since adding 0 does not change the sum, it can be simplified to:
4000 + 80 + 5

The expanded form of the number 337 is:

• 300 - representing the hundreds place
• 30 - representing the tens place
• 7 - representing the ones place

The purpose of a number line is to visually represent numbers in a sequence. Here's how it works:

• Shows numbers in order from smallest to largest.
• Helps in understanding the position of numbers relative to each other.

To arrange the prices in increasing order:

• First, compare all the prices: ₹1099, ₹1899, ₹1986.
• Start with the smallest: ₹1099.
• Next is: ₹1899.
• Finally, the largest is: ₹1986.

Therefore, the correct arrangement is: ₹1099, ₹1899, ₹1986.

The number 1002 can be broken down into its place values as follows:

• 1 Thousand
• 0 Hundreds
• 0 Tens
• 2 Ones
