Let’s solve this step by step.
This worksheet is about
number bonds. A number bond shows how two smaller numbers (called “parts”) add up to make one bigger number (called the “whole”).
Each diagram has:
- One big circle on top → that’s the
whole
- Two small circles below → those are the
parts
- Underneath, there’s an addition sentence: ___ + ___ = ___
Since no numbers are filled in yet, we can choose any numbers we want — as long as they make sense! Let’s pick simple numbers so it’s easy to understand.

Let’s fill in the first row:
First diagram:
- Top circle (whole): 5
- Bottom left (part): 2
- Bottom right (part): 3
→ Equation: 2 + 3 = 5
✔
Second diagram:
- Whole: 6
- Parts: 4 and 2
→ Equation: 4 + 2 = 6
✔
Third diagram:
- Whole: 7
- Parts: 3 and 4
→ Equation: 3 + 4 = 7
✔
---
Second row:
Fourth diagram:
- Whole: 8
- Parts: 5 and 3
→ Equation: 5 + 3 = 8
✔
Fifth diagram:
- Whole: 9
- Parts: 6 and 3
→ Equation: 6 + 3 = 9
✔
Sixth diagram:
- Whole: 10
- Parts: 7 and 3
→ Equation: 7 + 3 = 10
✔
---
Third row:
Seventh diagram:
- Whole: 4
- Parts: 1 and 3
→ Equation: 1 + 3 = 4
✔
Eighth diagram:
- Whole: 5
- Parts: 2 and 3
→ Equation: 2 + 3 = 5
✔
Ninth diagram:
- Whole: 6
- Parts: 4 and 2
→ Equation: 4 + 2 = 6
✔

All equations check out. We used simple numbers that add correctly. You could use different numbers too — as long as the two bottom numbers add up to the top number!
Final Answer:
You can fill each number bond with any correct set of numbers. Here’s one possible complete answer:
Row 1:
2 + 3 = 5
4 + 2 = 6
3 + 4 = 7
Row 2:
5 + 3 = 8
6 + 3 = 9
7 + 3 = 10
Row 3:
1 + 3 = 4
2 + 3 = 5
4 + 2 = 6
