Problem Explanation:
This worksheet asks you to break down two-digit numbers into
tens and
ones.
For example, the number
30 is made up of:
-
3 tens (because 3 × 10 = 30)
-
0 ones (because there are no extra units)
So, we write:
- Tens:
3
- Ones:
0
We’ll apply this logic to all the numbers on the sheet.

🎯 How to Remember:
- The
first digit in a two-digit number is the
number of tens.
- The
second digit is the
number of ones.
Example: In
48, 4 is in the tens place → 4 tens, and 8 is in the ones place → 8 ones.
You can use this rule for any two-digit number!
