Let me work through this number bonds worksheet step by step.
Number bonds show how numbers can be split into parts or combined to make a whole. The main circle contains the total, and the two smaller circles contain the parts that add up to that total.
So if we have:
- Main circle = Part 1 + Part 2
Let me solve each one:
Row 1:
1. Main: 16, Parts: 8 and ? → 16 - 8 = 8 ✓
2. Main: 14, Parts: ? and 12 → 14 - 12 = 2 ✓
3. Main: ?, Parts: 8 and 12 → 8 + 12 = 20 ✓
Row 2:
4. Main: ?, Parts: 15 and 5 → 15 + 5 = 20 ✓
5. Main: ?, Parts: 10 and 10 → 10 + 10 = 20 ✓
6. Main: 13, Parts: ? and 8 → 13 - 8 = 5 ✓
Row 3:
7. Main: 15, Parts: 7 and ? → 15 - 7 = 8 ✓
8. Main: ?, Parts: 15 and 3 → 15 + 3 = 18 ✓
9. Main: 16, Parts: ? and 11 → 16 - 11 = 5 ✓
Row 4:
10. Main: 18, Parts: 10 and ? → 18 - 10 = 8 ✓
11. Main: 12, Parts: 6 and ? → 12 - 6 = 6 ✓
12. Main: ?, Parts: 14 and 6 → 14 + 6 = 20 ✓
Let me verify my answers:
1. 8 + 8 = 16 ✓
2. 2 + 12 = 14 ✓
3. 8 + 12 = 20 ✓
4. 15 + 5 = 20 ✓
5. 10 + 10 = 20 ✓
6. 5 + 8 = 13 ✓
7. 7 + 8 = 15 ✓
8. 15 + 3 = 18 ✓
9. 5 + 11 = 16 ✓
10. 10 + 8 = 18 ✓
11. 6 + 6 = 12 ✓
12. 14 + 6 = 20 ✓
All calculations check out!
Final Answer:
The missing numbers are (reading left to right, top to bottom):
8, 2, 20, 20, 20, 5, 8, 18, 5, 8, 6, 20
