🎆What is Place Value?

• Place Value: The value of each digit in a number based on its position.
• Positions: In a three-digit number, the positions are hundreds, tens, and ones.

🧨 Place Value Names:

Hundreds Place:

The digit in the hundreds place represents how many hundreds are in the number.

• Example: In 452, the digit 4 is in the hundreds place, so its value is 400.

Tens Place:

The digit in the tens place represents how many tens are in the number.

• Example: In 452, the digit 5 is in the tens place, so its value is 50.

Ones Place:

The digit in the ones place represents the number of ones.

• Example: In 452, the digit 2 is in the ones place, so its value is 2.

✨Reading Numbers Using Place Value Names:

When reading a three-digit number, start with the hundreds, then the tens, and finally the ones.

• Example: The number 786 is read as “seven hundred eighty-six.”

Practice: Read various three-digit numbers aloud to understand how each digit’s place value is named.

🎉 Writing Numbers in Expanded Form:

Expanded Form: Writing a number by showing the value of each digit.

• Example: 326 in expanded form is 300 + 20 + 6.

Practice: Write numbers in expanded form to reinforce the understanding of place value names.

🎟 Identifying Place Value Names:

Place Value Identification: Given a number, identify the value of each digit.

• Example: In 593, the digit 5 is in the hundreds place (500), 9 is in the tens place (90), and 3 is in the ones place (3).

🎨 Using Place Value Charts:

Place Value Chart: A visual tool to help students identify and name place values.

Example: For the number 642:

• Hundreds: 6 (Six hundred)

• Tens: 4 (Forty)

• Ones: 2 (Two)

Practice: Fill in place value charts with different numbers to see how each digit fits into its place value.

🎫Linking Place Value Names to Real-Life Examples:

Practical Application: Relate place value names to real-life examples like counting money (hundred-dollar bills, ten-dollar bills, one-dollar bills).

• Example: If you have 245 dollars, you have 2 hundred-dollar bills, 4 ten-dollar bills, and 5 one-dollar bills.
