How to Write 4 Digit Numbers in Expanded Form with Place Value
FAQs on Expanded Form Worksheet: 4 Digit Numbers for Class 3
1. How do you write 4 digit numbers in expanded form?
To write a 4-digit number in expanded form, you break it down into the sum of its place values for thousands, hundreds, tens, and ones.
- First, identify the value of each digit based on its position.
- For example, in the number 5432, the '5' is in the thousands place (5000), '4' is in the hundreds place (400), '3' is in the tens place (30), and '2' is in the ones place (2).
- The expanded notation is written as: 5432 = 5000 + 400 + 30 + 2.
2. How do you write 5432 in expanded form?
Writing 5432 in expanded form involves showing the value of each digit as a sum.
- 5 is in the thousands place, so its value is 5000.
- 4 is in the hundreds place, so its value is 400.
- 3 is in the tens place, so its value is 30.
- 2 is in the ones place, so its value is 2.
Therefore, the expanded form is 5000 + 400 + 30 + 2. This method of number decomposition helps in understanding place value.
3. What is the expanded form of a 4-digit number with a zero?
When a 4-digit number includes a zero, that place value is represented as '0' in the expanded form, or it can be skipped.
- For the number 1009, the expanded form is 1000 + 0 + 0 + 9.
- For the number 7052, the expanded form is 7000 + 0 + 50 + 2.
This practice helps Class 3 students understand that zero acts as a placeholder in the place value chart.
