### Content:

1. Place Value Explanation:
• Place value refers to the value of a digit based on its position in a number.
• Example: In the number 435, the place value of 5 is â€˜unitsâ€™, 3 is â€˜tensâ€™, and 4 is â€˜hundredsâ€™.
2. Writing Numbers in Expanded Form:
• Breaking down a number based on its place values.
• Example: 435 = 400 + 30 + 5.
3. Identifying Place Values:
• Identifying the place value of each digit in a number.
• Example: In 547, 7 is in the â€˜unitsâ€™ place, 4 is in the â€˜tensâ€™ place, and 5 is in the â€˜hundredsâ€™ place.
4. Comparing Numbers Using Place Value:
• Using place value to compare and order numbers.
• Example: 435 is greater than 345 because the hundreds digit 4 is greater than 3.
