You're looking at a
Skip Counting Worksheet from KiddoSheet. The goal is to fill in the missing numbers by identifying the skip counting pattern in each row — that is, counting forward or backward by a consistent interval (like 3s, 6s, etc.).
Let’s solve each row one by one.
---
🔹 Row 1: `3, 6, __, __, 15`
- From 3 to 6 → +3
- From 6 to ? → should be +3 →
9
- Next → 9 + 3 =
12
- Then 12 + 3 = 15
✔
✔ Answer: 9, 12
---
🔹 Row 2: `33, 30, __, 24, __, 18`
- 33 → 30 → -3
- So it’s counting
backwards by 3s
- 30 - 3 =
27
- 27 - 3 = 24
✔
- 24 - 3 =
21
- 21 - 3 = 18
✔
✔ Answer: 27, 21
---
🔹 Row 3: `__, 39, __, __, 48, 51`
- 48 → 51 → +3 → so likely counting
forward by 3s
- Let’s work backwards:
- Before 48: 48 - 3 =
45
- Before 45: 45 - 3 =
42
- Before 42: 42 - 3 =
39 ✔ (matches given)
- Before 39: 39 - 3 =
36
✔ Answer: 36, 42, 45
---
🔹 Row 4: `69, __, __, 60, __, 54`
- 60 → 54 → -6 → so maybe counting
backwards by 3s? Let’s check:
- 60 - 3 = 57, 57 - 3 = 54
✔
- So step is -3
- Before 60: 60 + 3 =
63, then 63 + 3 =
66
- After 60: 60 - 3 =
57
✔ Answer: 66, 63, 57
---
🔹 Row 5: `72, __, __, 81, __, 87`
- 81 → 87 → +6 → but let’s check if it’s +3:
- 81 + 3 = 84, 84 + 3 = 87
✔
- So step is +3
- Before 81: 81 - 3 =
78, then 78 - 3 =
75
- After 81: 81 + 3 =
84
✔ Answer: 75, 78, 84
---
🔹 Row 6: `105, __, __, 96, __, 90`
- 96 → 90 → -6 → again, check step of -3:
- 96 - 3 = 93, 93 - 3 = 90
✔
- So step is -3
- Before 96: 96 + 3 =
99, then 99 + 3 =
102
- After 96: 96 - 3 =
93
✔ Answer: 102, 99, 93

##
✔ Final Answer Summary:
Row 1: 9, 12
Row 2: 27, 21
Row 3: 36, 42, 45
Row 4: 66, 63, 57
Row 5: 75, 78, 84
Row 6: 102, 99, 93

## 🧠 Explanation:
Skip counting means counting by a fixed number repeatedly — like counting by 2s (2, 4, 6…), 3s (3, 6, 9…), etc. In this worksheet, all rows use
skip counting by 3s, either forward (+3) or backward (-3). You just need to find the pattern and fill in the gaps!
This helps kids build number sense, understand multiples, and prepare for multiplication.
Let me know if you’d like a printable version or more practice! 😊
Parent Tip: Review the logic above to help your child master the concept of counting by 3s worksheet.
