Frequently Asked Questions
How do we compare two 3-digit numbers if the hundreds digits are the same?
If the hundreds digits are the same, compare the tens digits. If the tens digits are also the same, compare the ones digits to decide which number is larger.
What is the difference between face value and place value?
Face value is the actual digit itself, while place value is the value of the digit based on its position (hundreds, tens, or ones) in the number.
How can I easily write a number name for a 3-digit number?
Read the hundreds place first (e.g., 'four hundred'), followed by the tens and ones together (e.g., 'fifty-six'), making 'four hundred fifty-six'.
