Counting Backwards Worksheets - 15 Worksheets Library - Free Printable

Explanation:
We are asked to count from 20 to 0 backwards. That means we list all whole numbers starting at 20 and decreasing by 1 each time, until we reach 0.

Let’s write them out step by step:

20,
19,
18,
17,
16,
15,
14,
13,
12,
11,
10,
9,
8,
7,
6,
5,
4,
3,
2,
1,
0.

Now, check the worksheet: some numbers are already filled in — like 20, 19, 15, 13, 12, 9, 6, 3 — and there are apple shapes where missing numbers should go.

Let’s find the missing positions by matching the sequence:

Row 1: 20, 19, [apple], [apple], [apple], 15
→ After 19 comes 18, then 17, then 16, then 15.
So apples = 18, 17, 16.

Row 2: [apple], 13, 12, [apple], [apple]
→ Before 13 is 14. After 12 is 11, then 10.
So apples = 14, 11, 10.

Row 3: 9, [apple], [apple], 6, [apple]
→ After 9 is 8, then 7, then 6. After 6 is 5.
So apples = 8, 7, 5.

Row 4: [apple], 3, [apple], [apple], [apple]
→ Before 3 is 4. After 3 is 2, then 1, then 0.
So apples = 4, 2, 1, 0.

Wait — let’s double-check how many apple slots there are total.

Count the apple outlines in the image (from description):
Row 1: 3 apples
Row 2: 3 apples
Row 3: 3 apples
Row 4: 4 apples
Total = 13 apples.

Now list all numbers from 20 down to 0: that’s 21 numbers (20 through 0 inclusive).

Given numbers already written:
20, 19, 15, 13, 12, 9, 6, 3 → that’s 8 numbers.

21 total − 8 given = 13 missing → matches number of apples. Good.

Now fill in missing numbers in order they appear left-to-right, top-to-bottom:

1. After 19 → 18
2. Next → 17
3. Next → 16
4. Before 13 → 14
5. After 12 → 11
6. Next → 10
7. After 9 → 8
8. Next → 7
9. After 6 → 5
10. Before 3 → 4
11. After 3 → 2
12. Next → 1
13. Last → 0

So the missing numbers (in order of apple positions) are:
18, 17, 16, 14, 11, 10, 8, 7, 5, 4, 2, 1, 0.

But the question just says “Count from 20 to 0 backwards.” It doesn’t ask for a list — it's a worksheet where the student fills in the blanks. Since the instruction is simply to *count*, and the format is a worksheet with blanks, the expected final answer is the full backward count sequence.

However, per instructions, we must give only the final correct answer, after reasoning.

The full backward count from 20 to 0 is:

20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.

That’s the complete sequence.

Final Answer:
20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
