Ordering Numbers - The Step-by-Step Method
For whole numbers:
- Compare the number of digits first (more digits = bigger number)
- If same number of digits, compare from left to right
- Find the first column where digits differ
- The number with the larger digit in that column is bigger
For decimals:
- Compare the whole number parts first
- If whole parts are equal, line up the decimal points
- Add zeros to make all decimals the same length
- Compare digit by digit from left to right after the decimal point
For negative numbers:
- All negative numbers are less than all positive numbers
- For negative numbers: closer to zero = bigger (e.g., -2 > -5)
- Think of a number line: left is smaller, right is bigger
