Let’s work through each box one by one.
We’re looking for the missing number in each “Part/Part/Whole” box.
The top number is the
whole.
The bottom two numbers are the
parts.
So: Part + Part = Whole
---
Box 1 (top left):
Whole = 9
Parts = 2 and ?
So: 2 + ? = 9 → ? = 9 - 2 =
7
Box 2 (top middle):
Whole = ?
Parts = 5 and 0
So: 5 + 0 =
5
Box 3 (top right):
Whole = 10
Parts = 7 and ?
So: 7 + ? = 10 → ? = 10 - 7 =
3
Box 4 (middle left):
Whole = ?
Parts = 3 and 4
So: 3 + 4 =
7
Box 5 (middle center):
Whole = 8
Parts = ? and 5
So: ? + 5 = 8 → ? = 8 - 5 =
3
Box 6 (middle right):
Whole = ?
Parts = 4 and 4
So: 4 + 4 =
8
Box 7 (bottom left):
Whole = 9
Parts = ? and 6
So: ? + 6 = 9 → ? = 9 - 6 =
3
Box 8 (bottom center):
Whole = ?
Parts = 8 and 2
So: 8 + 2 =
10
Box 9 (bottom right):
Whole = 7
Parts = 6 and ?
So: 6 + ? = 7 → ? = 7 - 6 =
1

Final Answer:
7, 5, 3, 7, 3, 8, 3, 10, 1
Parent Tip: Review the logic above to help your child master the concept of part part whole worksheet.
