What to Focus On
- Digits are 0 to 9.
- Smallest one-digit number is 0, largest is 9.
- Smallest two-digit number is 10, largest is 99.
- Four-digit numbers have Thousands, Hundreds, Tens, and Ones places.
- Place value depends on the digit's position.
- Face value of a digit is the digit itself and does not change with position.
- Abacus has spikes for Thousands, Hundreds, Tens, and Ones.
- Each ring represents one unit of that place.
- No ring means 0 in that place.
Common Mistakes to Avoid
Zero in a number means it's smaller, so 302 is less than 320 because it has a zero.
The place value of a digit is the digit itself, so the place value of 5 in 253 is 5.
When writing the smallest 4-digit number using digits 3, 0, 5, 8, we start with 0 like 0358.
Memory Tips
Place Value: Thousands, Hundreds, Tens, Ones
Expanded Form: Breaking numbers into parts
Face Value vs Place Value
Zero in a number means no rings on abacus
