Leap Year Skip Counting worksheet with frogs and lily pads for learning even-numbered years.

Let's solve the "Leap Year Skip Counting" worksheet step by step.

🔍 Understanding Leap Years

A leap year occurs every 4 years, except for years that are divisible by 100 but not by 400.
For example:
- 2000 was a leap year (divisible by 400).
- 1900 was not a leap year (divisible by 100 but not by 400).

But in this worksheet, since we're dealing with recent and future years (2020–2052), all years divisible by 4 are leap years.

So, we're skip counting by 4s to fill in the missing leap years.

🐸 Given Information

We have a frog-themed path with circles connected by dotted lines. Some years are filled in:

- 2020
- 2024
- 2040
- 2052

We need to fill in the missing leap years along the path, skipping by 4 each time.

✔ Step-by-step: Fill in the missing years

Start from 2020, add 4 each time:

1. 2020 → given
2. 2024 → given
3. 2028 → missing
4. 2032 → missing
5. 2036 → missing
6. 2040 → given
7. 2044 → missing
8. 2048 → missing
9. 2052 → given

Now let’s map these onto the diagram.

Looking at the layout:

```
[2020] ————→ [2024]
↓ ↓
[_____] [_____]
↓ ↓
[_____] [2040]
↓ ↓
[2052] [_____]
```

Wait — actually, the diagram is arranged like a path with frogs jumping between lily pads (ovals). Let's reconstruct the path based on typical layout:

From the image description and standard design:

- The path starts at 2020
- Then goes to 2024
- Then jumps to 2040 (skipping some)
- Then to 2052

But that skips too much. So likely, it's a loop or zigzag path.

Let’s assume the sequence follows the chronological order of leap years:

> 2020 → 2024 → 2028 → 2032 → 2036 → 2040 → 2044 → 2048 → 2052

So the missing numbers are:

- After 2024 → 2028
- Then → 2032
- Then → 2036
- Then → 2040 (given)
- Then → 2044
- Then → 2048
- Then → 2052 (given)

Now, let's match them to the empty ovals.

Assuming the path goes like this:

1. Start: 2020
2. Next: 2024
3. Then: 2028 (first blank)
4. Then: 2032 (second blank)
5. Then: 2036 (third blank)
6. Then: 2040 (given)
7. Then: 2044 (fourth blank)
8. Then: 2048 (fifth blank)
9. Then: 2052 (given)

So the missing leap years are:

- 2028
- 2032
- 2036
- 2044
- 2048

✔ Final Answer: Fill in the blanks with:

- First blank after 2020 → 2028
- Second → 2032
- Third → 2036
- Fourth → 2044
- Fifth → 2048

(These are the five missing leap years in the sequence.)

📝 Summary

Leap Year Sequence:
2020, 2024, 2028, 2032, 2036, 2040, 2044, 2048, 2052

✔ All values increase by 4.

---

✔ Solution:

Fill in the blanks with:

- 2028
- 2032
- 2036
- 2044
- 2048

This completes the leap year skip counting pattern!
