Numbers 
to 1000
Introduction
The Building Blocks of Numbers
Numbers up to 1000 have hundreds, tens, and ones. Each position tells us something 
special about the number.
Why Place Value Matters
Understanding place value helps in reading, writing, and comparing numbers. It's like 
having a secret code to understand numbers better!

Hundreds, Tens, and Ones
Ones Place
6 = 6 ones
Tens Place
4 = 40 (4 tens)
Hundreds Place
2 = 200 (2 hundreds)
Every number has digits that hold different values depending on their position. In our 
example number 2 46, each digit has a special job.
When we add these values together (200 + 40 + 6), we get our complete number: 246. 
Understanding place value helps us see that a digit's position determines its value!

Let's Solve
Q u e s t i o n :
What is the place value of 7 in 47 2?
Solution
Identify the digit
Locate 7 in the number 472
Find its place
7 is in the tens place
Calculate the value
When a digit is in the tens place, we 
multiply it by 10 to find its value. So, the 
value of 7 in 472 is 70.
7 tens = 70
