Whole Numbers up to 10,000

Hello class! Today we will learn about whole numbers that go up to ten thousand. These numbers are used when we count people, money, or things in our market. Let us see how they are written and read.

💡 Place Value Basics

Every whole number has places: units, tens, hundreds, and thousands. The digit on the right is the units (1s), next is tens (10s), then hundreds (100s), and finally thousands (1,000s). For example, in 3,527 the 7 is units, 2 is tens, 5 is hundreds and 3 is thousands.

🧠 Reading Numbers up to 10,000

To read a number, say each place value from left to right. 4,089 is read as "four thousand eighty‑nine". If a place has a zero, we still mention the higher places: 2,030 is "two thousand thirty".

🔍 Writing Numbers from Words

When you hear a number in words, write the digits in the right places. "Seven thousand two hundred fifty‑four" becomes 7,254. Remember the order: thousands, hundreds, tens, units.

📌 Using Money (Naira and Kobo)

Whole numbers are also used for money. If you have 6,750 naira, you write it as 6,750₦. It means six thousand seven hundred fifty naira and zero kobo.

⭐ Remember

  • Place values are units, tens, hundreds, thousands.
  • Read numbers from left to right, naming each place.
  • Zero in a place does not change the reading of higher places.
  • When writing numbers from words, keep the order thousands‑hundreds‑tens‑units.
  • Money amounts are written the same way as whole numbers.

Write the following amount in words: 9,306 naira.
