10 Counting - Recognizing Place Value
Understanding Place Value Recognition
Place value recognition is the ability to look at any number up to 999 and identify how many hundreds, tens, and ones it contains. This skill, sometimes called "10 counting" or "counting by place values," is fundamental to understanding our number system and performing calculations with larger numbers.
What is Place Value Recognition?
Place value recognition means: - Looking at a number like 347 - Identifying each digit's value based on its position - Understanding that 347 = 3 hundreds + 4 tens + 7 ones - Breaking down numbers into their component parts
Example: The number 582 - Hundreds place: 5 (represents 500) - Tens place: 8 (represents 80) - Ones place: 2 (represents 2) - Total: 500 + 80 + 2 = 582
Why Place Value Recognition Matters
Recognizing place value helps you: - Read numbers correctly - know what each digit means - Compare numbers - determine which is larger - Add and subtract - understand regrouping - Round numbers - estimate to nearest ten or hundred - Solve problems - work with real-world quantities - Build number sense - develop mathematical intuition
The Three Place Values Up to 999
Every number from 100 to 999 has three distinct places.
Hundreds Place (Left-most Digit)
The hundreds place is the first position from the left.
Value: Each digit represents × 100
Examples: - In 234, the 2 is in the hundreds place = 200 - In 567, the 5 is in the hundreds place = 500 - In 891, the 8 is in the hundreds place = 800
Range: The hundreds digit can be: - 1, 2, 3, 4, 5, 6, 7, 8, or 9 (not 0, or it wouldn't be a three-digit number)
Tens Place (Middle Digit)
The tens place is the second position from the left.
Value: Each digit represents × 10
Examples: - In 234, the 3 is in the tens place = 30 - In 567, the 6 is in the tens place = 60 - In 891, the 9 is in the tens place = 90
Range: The tens digit can be: - 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 (includes zero!)
Ones Place (Right-most Digit)
The ones place is the last position on the right.
Value: Each digit represents × 1
Examples: - In 234, the 4 is in the ones place = 4 - In 567, the 7 is in the ones place = 7 - In 891, the 1 is in the ones place = 1
Range: The ones digit can be: - 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 (includes zero!)
Breaking Down Numbers by Place Value
Let's practice identifying place values in various numbers.
Example 1: 456
Breakdown:
Number: 456
Position: H T O
Digits: 4 5 6
Hundreds: 4 → 4 × 100 = 400
Tens: 5 → 5 × 10 = 50
Ones: 6 → 6 × 1 = 6
Total: 400 + 50 + 6 = 456 ✓
Example 2: 703
Breakdown:
Number: 703
Position: H T O
Digits: 7 0 3
Hundreds: 7 → 7 × 100 = 700
Tens: 0 → 0 × 10 = 0
Ones: 3 → 3 × 1 = 3
Total: 700 + 0 + 3 = 703 ✓
Notice: The tens place has zero!
Example 3: 890
Breakdown:
Number: 890
Position: H T O
Digits: 8 9 0
Hundreds: 8 → 8 × 100 = 800
Tens: 9 → 9 × 10 = 90
Ones: 0 → 0 × 1 = 0
Total: 800 + 90 + 0 = 890 ✓
Notice: The ones place has zero!
Example 4: 100
Breakdown:
Number: 100
Position: H T O
Digits: 1 0 0
Hundreds: 1 → 1 × 100 = 100
Tens: 0 → 0 × 10 = 0
Ones: 0 → 0 × 1 = 0
Total: 100 + 0 + 0 = 100 ✓
Notice: Both tens and ones are zero!
Example 5: 999
Breakdown:
Number: 999
Position: H T O
Digits: 9 9 9
Hundreds: 9 → 9 × 100 = 900
Tens: 9 → 9 × 10 = 90
Ones: 9 → 9 × 1 = 9
Total: 900 + 90 + 9 = 999 ✓
The largest three-digit number!

Expanded Form and Standard Form
Standard Form
Standard form is the normal way we write numbers: 347, 625, 890
Expanded Form
Expanded form shows the value of each place separately.
Examples:
Standard: 247 Expanded: 200 + 40 + 7

Standard: 906 Expanded: 900 + 0 + 6 (or 900 + 6)
Standard: 780 Expanded: 700 + 80 + 0 (or 700 + 80)
Converting Between Forms
From Standard to Expanded:
672 → Break down each digit - Hundreds: 6 = 600 - Tens: 7 = 70 - Ones: 2 = 2 - Expanded: 600 + 70 + 2
From Expanded to Standard:
400 + 30 + 9 → Identify each place - Hundreds: 400 = 4 - Tens: 30 = 3 - Ones: 9 = 9 - Standard: 439
Word Form and Place Value
We can also write numbers using words to describe their place values.
Writing in Word Form

Measurements
Distance: 523 meters - 5 hundreds, 2 tens, 3 ones
Weight: 678 grams - 6 hundreds, 7 tens, 8 ones
Practice Activities
Activity 1: Place Value Scavenger Hunt
Find three-digit numbers around you: - Page numbers in books - Numbers on signs - Addresses - Product numbers
For each number, identify: - How many hundreds? - How many tens? - How many ones?
Activity 2: Build-a-Number Game
Materials: Dice or number cards (0-9)
How to play: 1. Roll/draw three times 2. First roll = hundreds digit 3. Second roll = tens digit 4. Third roll = ones digit 4. Build the number and say it aloud 5. Write in expanded form
Activity 3: Place Value Bingo

Common Mistakes and Solutions
Mistake 1: Confusing digit position
Problem: In 347, thinking the 4 is in the hundreds place
Solution: Count from the left: First digit (3) is hundreds, second (4) is tens, third (7) is ones.
Mistake 2: Ignoring zeros
Problem: Reading 502 and saying "5 hundreds, 2 ones" (forgetting to mention 0 tens)
Solution: Always check all three places. Zero is a digit too—it shows that place is empty.
Mistake 3: Wrong digit values
Problem: Saying 5 in the tens place equals 5
Solution: Remember position matters! 5 in tens place = 50, not 5.
Mistake 4: Incorrect expanded form
Problem: Writing 347 as 3 + 4 + 7
Solution: Show the place value: 300 + 40 + 7

Place value recognition—understanding that each digit's position determines its value—is one of the most fundamental concepts in mathematics. By mastering the ability to identify hundreds, tens, and ones in any number up to 999, you build the foundation for all future work with larger numbers and complex calculations. Practice looking at numbers and mentally breaking them down into their component parts, and you'll develop the number sense that makes mathematics logical, predictable, and manageable.
