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 ‘units’, 3 is ‘tens’, and 4 is ‘hundreds’.
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 ‘units’ place, 4 is in the ‘tens’ place, and 5 is in the ‘hundreds’ 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.
