Let’s solve each Number Bonds Challenge step by step.
Number bonds mean we’re adding two numbers to make a total — usually 10, 20, or 100 in these challenges.
We’ll go challenge by challenge and fill in the missing number that makes the bond correct.

Number Bonds Challenge 1 (to make 10)
- 4 + 5 =
9 → Wait! That doesn’t make 10. Let me check again.
Actually, looking at the layout, it seems like each row is meant to add up to 10? But 4+5=9… Hmm.
Wait — maybe I misread. Let’s look carefully:
In Challenge 1:
First row:
4 + 5 = ? → 9
1 + 6 = ? → 7
3 + 8 = ? → 11 ← That can’t be right for “number bonds to 10”.
Hold on — perhaps the title “Number Bonds Challenges” means each problem is asking you to find what adds with the first number to make 10? But the format shows “a + b = c”, so maybe it’s just simple addition?
But then why call it “number bonds”? Usually number bonds are about making a target number.
Looking at Challenge 3: “10 + 10 = ?” — that’s 20. And later “80 + 20 = 100”. So actually, these are just basic addition problems grouped by difficulty.
So let’s treat them as straightforward addition.
I’ll solve each one accurately.

Challenge 1:
Row 1:
4 + 5 =
9
1 + 6 =
7
3 + 8 =
11
Row 2:
3 + 4 =
7
5 + 4 =
9
7 + 1 =
8
Row 3:
1 + 7 =
8
2 + 5 =
7
2 + 5 =
7
Row 4:
6 + 2 =
8
4 + 6 =
10
2 + 5 =
7
Wait — this doesn’t seem consistent. Maybe the worksheet has typos? Or maybe I’m misunderstanding.
