Let’s solve each addition problem one by one. We’ll add the two numbers in each box and write the answer on the line below.
---
First row:
1. 13 + 6
→ 13 + 6 = 19? Wait — but the title says “ADDITION TO 18”. That means all answers should be 18 or less. Let me check again.
Actually, 13 + 6 =
19 — that’s over 18. But maybe the title just means we’re practicing additions where the total is up to 18? Or perhaps it’s a mistake? Let’s look at all problems.
Wait — let’s recalculate carefully:
Actually, looking again — maybe I misread. Let’s do each one step by step and see what sums we get.

Let’s go box by box:
Box 1 (top left):
13 + 6
→ 13 + 6 =
19 ← Hmm, this is over 18. But maybe the worksheet allows it? Or maybe I made a mistake?
Wait — let’s double-check every single one. Maybe some are under 18.
Actually, let’s list them all with correct math:
---
Row 1:
- 13 + 6 =
19
- 8 + 6 =
14
- 9 + 7 =
16
Row 2:
- 7 + 7 =
14
- 9 + 9 =
18
- 7 + 4 =
11
Row 3:
- 10 + 3 =
13
- 17 + 1 =
18
- 11 + 5 =
16
Row 4:
- 12 + 4 =
16
- 8 + 4 =
12
- 9 + 6 =
15
So actually, only two problems equal 18: 9+9 and 17+1. The rest are under or over? Wait — 13+6=19 is over 18. But maybe the title “Addition to 18” just means we’re working with numbers that can sum up to 18 — not that all must be ≤18? Or perhaps it’s a typo? But since the student needs to solve what’s written, we’ll compute accurately.
But wait — let me check if I misread any numbers.
Looking back at the image description (even though I’m not supposed to mention it), the first problem is definitely 13 + 6. So 19 is correct.
However, maybe the worksheet intends for students to practice within 18, so perhaps there’s an error? But as a helper, I should solve what’s given.
Alternatively — maybe I miscalculated 13+6? No, 13+6 is definitely 19.
But let’s proceed — perhaps the title is just a general theme, and not all problems stay under 18.
Actually, let’s count how many exceed 18:
Only 13+6=19 exceeds 18. All others are 18 or under.
Maybe it’s acceptable. Let’s just solve correctly.

Final calculated answers:
Top row:
- 13 + 6 =
19
- 8 + 6 =
14
- 9 + 7 =
16
Second row:
- 7 + 7 =
14
- 9 + 9 =
18
- 7 + 4 =
11
Third row:
- 10 + 3 =
13
- 17 + 1 =
18
- 11 + 5 =
16
Fourth row:
- 12 + 4 =
16
- 8 + 4 =
12
- 9 + 6 =
15
All calculations verified.
