What is it?

Counting by thousands means listing numbers by adding 1000 each time. You start from a number and keep jumping forward by 1000 to find the next number in the sequence. It helps us understand how large numbers grow.

Simple Example

Quick Example

Imagine your school has collected 1000 rupees for a charity drive. If they collect another 1000 rupees, they will have 2000 rupees. If they collect 1000 more, they will have 3000 rupees. This is counting by thousands: 1000, 2000, 3000, and so on.

Worked Example

Step-by-Step

Let's count by thousands, starting from 5000.

1. Start with the given number: 5000.
---
2. To find the next number, add 1000 to the current number: 5000 + 1000 = 6000.
---
3. To find the third number, add 1000 to the previous result: 6000 + 1000 = 7000.
---
4. To find the fourth number, add 1000 again: 7000 + 1000 = 8000.
---
5. To find the fifth number, add 1000 one last time: 8000 + 1000 = 9000.

So, counting by thousands starting from 5000 gives us: 5000, 6000, 7000, 8000, 9000.

Why It Matters

Understanding how to count by thousands is key for working with big numbers, which you'll see in many subjects like finance, science, and even daily life. It's crucial for careers like banking, engineering, and data analysis, where you deal with large quantities and sums every day.

Common Mistakes

MISTAKE: Adding 100 instead of 1000 (e.g., 2000, 2100, 2200) | CORRECTION: Always ensure you are adding exactly 1000 to the previous number to jump by thousands.

MISTAKE: Forgetting to carry over when adding (e.g., 9000 + 1000 = 1000 instead of 10000) | CORRECTION: Remember place value; when you add 1000 to 9000, the thousands place becomes 10, which means 1 ten thousand.

MISTAKE: Starting from a number and just changing the last digit (e.g., 4000, 4001, 4002) | CORRECTION: Counting by thousands means the 'thousands' digit (or the digit before the last three zeros) is the one that changes, increasing by one each time.

Practice Questions

Try It Yourself

QUESTION: Count by thousands, starting from 1000, for the next three numbers. | ANSWER: 1000, 2000, 3000, 4000

QUESTION: What are the next five numbers if you count by thousands, starting from 12000? | ANSWER: 12000, 13000, 14000, 15000, 16000, 17000

QUESTION: A factory produces 7000 biscuits in January. If it increases production by 1000 biscuits every month, how many biscuits will it produce in April? (Assume January is month 1). | ANSWER: January: 7000, February: 8000, March: 9000, April: 10000. So, 10000 biscuits.

MCQ

Quick Quiz

Which sequence correctly shows counting by thousands?

1500, 2500, 3500

4000, 4001, 4002

6000, 7000, 8000

1000, 1100, 1200

The Correct Answer Is:

Option C shows each number increasing by exactly 1000 (6000 + 1000 = 7000, 7000 + 1000 = 8000). The other options show increments of 1000 but starting from a non-thousand number, or increments of 1, or increments of 100.

Real World Connection

In the Real World

When a big stadium in India sells tickets, they often announce sales in thousands. For example, if 2000 tickets are sold, then 3000, then 4000, they are counting by thousands to track progress. Similarly, government budgets or large project costs are often discussed in lakhs or crores, which are multiples of thousands.

Key Vocabulary
