Frog Life Cycle - Free worksheet - SKOOLGO - Free Printable

Let’s go step by step to number and name each stage of the frog life cycle.

The frog life cycle has 5 main stages, and they happen in a circle — starting from eggs, then tadpole, then growing legs, then losing tail, then adult frog. The arrows show the order.

We’ll start at the top right with the eggs, because that’s where frogs begin their life.

---

Step 1: Eggs (top right)
This is the first stage. Frogs lay eggs in water. They look like little jelly balls with tiny dots inside.
→ Number: 1
→ Name: Eggs

---

Step 2: Tadpole (bottom right)
After the eggs hatch, out comes a tadpole. It swims in water and breathes with gills. No legs yet!
→ Number: 2
→ Name: Tadpole

---

Step 3: Tadpole with back legs (bottom left)
Now the tadpole starts growing back legs first. Still has a long tail and lives in water.
→ Number: 3
→ Name: Tadpole with back legs

---

Step 4: Froglet (left middle)
Now it grows front legs too, and the tail gets shorter. It can start hopping on land but still has a stubby tail. This is called a “froglet.”
→ Number: 4
→ Name: Froglet

---

Step 5: Adult Frog (top left)
Finally, the tail disappears completely. Now it’s a full-grown frog that can live on land and jump around.
→ Number: 5
→ Name: Adult Frog

---

Let’s double-check the order using the arrows:

- Adult Frog → lays Eggs (arrow points from frog to eggs) ✔
- Eggs → hatch into Tadpole ✔
- Tadpole → grows back legs ✔
- Tadpole with back legs → becomes Froglet ✔
- Froglet → becomes Adult Frog ✔

Perfect! The cycle makes sense.

Final Answer:
Top left (adult frog): 5 - Adult Frog
Top right (eggs): 1 - Eggs
Middle right (tadpoles hatching): 2 - Tadpole
Bottom right (tadpole): 2 - Tadpole ← Wait, no — let's fix this.

Actually, looking again at the image layout:

There are 6 boxes? No — wait, there are 5 stages shown, but one stage (tadpole) appears twice? Let me recount the images:

Looking carefully:

1. Top center: big frog → adult frog
2. Top right: cluster of eggs → eggs
3. Middle right: cluster of developing embryos/tadpoles inside eggs → this is still part of egg stage or just after hatching? Actually, in most diagrams, this is “hatching tadpoles” or “early tadpole”

But standard frog life cycle is:

1. Eggs
2. Tadpole (with gills, no legs)
3. Tadpole with hind legs
4. Froglet (with all four legs, short tail)
5. Adult frog

In the image:

- Top right: eggs → Stage 1
- Below that: tadpoles emerging from eggs → still Stage 2 (Tadpole)
- Bottom right: single tadpole swimming → also Stage 2? But we need to assign unique numbers.

Wait — actually, the diagram shows 5 distinct illustrations:

Let’s list them clockwise from top right:

A. Cluster of eggs → Stage 1
B. Cluster of tadpoles breaking out of eggs → Stage 2 (still tadpole, but hatching)
C. Single tadpole → Stage 2? Or should we combine?

No — better to follow the arrow flow:

Arrow goes:

Adult Frog → Eggs → Hatching Tadpoles → Swimming Tadpole → Tadpole with legs → Froglet → Back to Adult Frog

That’s 6 steps? But usually it’s 5.

Actually, in many school worksheets, they simplify to 5 stages:

1. Eggs
2. Tadpole
3. Tadpole with legs
4. Froglet
5. Adult Frog

So perhaps the “cluster of hatching tadpoles” is still considered part of “Eggs” or early “Tadpole”.

But looking at the image, there are 5 labeled boxes connected by arrows forming a circle.

Let’s trace the arrows:

Start at top left: Adult Frog → arrow to top right: Eggs → arrow down to middle right: group of tadpoles in sacs → arrow down to bottom right: single tadpole → arrow left to bottom left: tadpole with back legs → arrow up to middle left: froglet → arrow up to top left: adult frog.

So actually, there are 6 images? No — count the drawings:

1. Top center: adult frog
2. Top right: eggs
3. Middle right: tadpoles in jelly (hatching)
4. Bottom right: free-swimming tadpole
5. Bottom left: tadpole with back legs
6. Middle left: froglet (has front and back legs, small tail)

That’s 6 stages? But traditionally it’s 5.

Wait — perhaps the “tadpoles in jelly” and “free-swimming tadpole” are both under “Tadpole” stage.

But the worksheet has 6 blank labels? Let me check the original image description.

User said: “Number and name each stage” — and there are 6 circles with lines pointing to 6 different images.

Images are:

- Top: adult frog
- Right-top: eggs
- Right-middle: cluster of developing tadpoles (still in egg mass?)
- Right-bottom: single tadpole
- Left-bottom: tadpole with back legs
- Left-middle: froglet (four legs, short tail)

So yes, 6 stages shown.

But standard biology teaches 5 stages. However, for this worksheet, since there are 6 blanks, we must fill all 6.

Perhaps the intended stages are:

1. Eggs
2. Embryo/Tadpole developing inside egg
3. Free-swimming tadpole
4. Tadpole with hind legs
5. Froglet
6. Adult frog

Yes, that fits.

So let’s assign:

Starting from eggs as #1:

→ Top right (eggs): 1 - Eggs

→ Middle right (tadpoles inside translucent sacs, eyes visible): 2 - Developing Tadpole or Hatching Tadpole

→ Bottom right (single tadpole swimming): 3 - Tadpole

→ Bottom left (tadpole with two back legs): 4 - Tadpole with Hind Legs

→ Middle left (frog with four legs and short tail): 5 - Froglet

→ Top left (full grown frog): 6 - Adult Frog

And the arrow from adult frog points to eggs, completing the cycle.

This matches the 6 labeled positions.

To confirm, let’s see if any stage is missing — no, this covers the full development.

Some curricula split “tadpole” into early and late, so having 6 stages is acceptable for this worksheet.

Final labeling:

- Top left (big frog): 6 - Adult Frog
- Top right (egg cluster): 1 - Eggs
- Middle right (tadpoles in jelly): 2 - Hatching Tadpole
- Bottom right (swimming tadpole): 3 - Tadpole
- Bottom left (tadpole with back legs): 4 - Tadpole with Hind Legs
- Middle left (small frog with tail): 5 - Froglet

Yes, this flows logically with the arrows.

Final Answer:
Top left (adult frog): 6 - Adult Frog
Top right (eggs): 1 - Eggs
Middle right (hatching tadpoles): 2 - Hatching Tadpole
Bottom right (swimming tadpole): 3 - Tadpole
Bottom left (tadpole with back legs): 4 - Tadpole with Hind Legs
Middle left (froglet): 5 - Froglet
