Place value names up to hundreds

key notes :

🎆1. 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.

🧨2. 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.

✨3. 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.

🎉4. 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.

🎟5. 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).

🎨6. 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.

🎫7. 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.
