Let's solve this step by step.
This worksheet is about
counting tens and ones using visual representations of cubes. The key instruction is:
> "Remember to count the TENS first, then the ONES."
Each
vertical column of 10 squares represents a
ten, and each
individual square (not in a column) represents a
one.
We’ll go through each problem one by one.

1)
-
Tens: One full column of 10 →
10
-
Ones: 4 separate squares →
4
- Total: 10 + 4 =
14
✔ Answer: 14

🔍 Explanation Summary:
- Each
vertical stack of 10 squares =
1 ten.
- Each
single square not in a stack =
1 one.
- Always count
tens first, then add the
ones.
- This helps build understanding of place value (tens and ones) up to 20.
