Let's solve the problem step by step.
This worksheet has three caterpillar-shaped columns, each with a counting instruction:
1.
Left Caterpillar: "Count back by 2s" starting from 10.
2.
Middle Caterpillar: "Count back by 5s" starting from 25.
3.
Right Caterpillar: "Count back by 10s" starting from 50.
We need to fill in the missing numbers in each column by subtracting the given amount (2, 5, or 10) each time.

🔹 Left Caterpillar: Count back by 2s
Start at 10 → then 8 → next?
- 8 - 2 =
6
- 6 - 2 =
4
- 4 - 2 =
2
- 2 - 2 =
0
So the sequence is:
- 10
- 8
-
6
-
4
-
2
-
0

🔹 Middle Caterpillar: Count back by 5s
Start at 25 → then 20 → next?
- 20 - 5 =
15
- 15 - 5 =
10
- 10 - 5 =
5
- 5 - 5 =
0
Sequence:
- 25
- 20
-
15
-
10
-
5
-
0

🔹 Right Caterpillar: Count back by 10s
Start at 50 → then 40 → next?
- 40 - 10 =
30
- 30 - 10 =
20
- 20 - 10 =
10
- 10 - 10 =
0
Sequence:
- 50
- 40
-
30
-
20
-
10
-
0

✔ Final Answer:
Left Column (count back by 2s):
10, 8,
6,
4,
2,
0
Middle Column (count back by 5s):
25, 20,
15,
10,
5,
0
Right Column (count back by 10s):
50, 40,
30,
20,
10,
0

💡
Explanation:
"Count back" means subtracting the given number each time. We keep subtracting until we reach 0 (or as many steps as there are blank boxes). This helps build number sense and understanding of subtraction patterns.
