Find the order
Key Notes :
π’ What Does βFind the Orderβ Mean?
It means arranging numbers from smallest to largest or largest to smallest.
- π Ascending Order β Small β Big
- π Descending Order β Big β Small
π Ascending Order (Small β Big)
- Start with the smallest number.
- Every next number should be bigger.
- Example:
23, 45, 78, 90 β¨
π Think of a stairs going up πͺβ¬οΈ
π Descending Order (Big β Small)
- Start with the largest number.
- Every next number should be smaller.
- Example:
90, 78, 45, 23 β¨
π Think of a stairs going down πͺβ¬οΈ
π Compare Before You Order
Look at numbers from:
π Left to Right
π Compare digits
- Hundreds π’
- Tens π
- Ones 1οΈβ£
Example:
- 345 vs 312 β Compare hundreds β 3 = 3
- Then compare tens β 4 > 1 β So 345 is bigger
π§ Use Place Value to Help
Place Value is very important!
A number with more digits is usually bigger.
Example:
- 234 (3-digit) > 99 (2-digit)
π Tip: Longer number β Larger value (most of the time!)
π― Ordering Mixed Numbers
If numbers have different digits like:
56, 7, 123, 89
π First arrange by number of digits, then compare.
Order: 7, 56, 89, 123
βοΈ Practice Example
Order in ascending order:
π’ 45, 12, 78, 34
π 12, 34, 45, 78
Order in descending order:
π’ 13, 27, 5, 92
π 92, 27, 13, 5
π Key Words to Remember
- π Ascending = Small β Big
- π Descending = Big β Small
- π’ Compare digits
- π§ Place value helps!
