Match the stages of the human life cycle with the correct labels in this educational activity.

Let’s match each picture to the correct life stage name.

1. First image: A small child sitting, holding a bottle and a drawing — this is a toddler (a young child who just started walking).
2. Second image: A boy with a backpack, looks like he’s going to school — this is a child (older than toddler, maybe 6–12 years old).
3. Third image: A baby in a diaper, laughing — this is clearly a baby.
4. Fourth image: A boy waving, wearing a yellow shirt — still young, but not a baby or toddler — this is also a child? Wait — let’s check again. Actually, looking at the options, we have “teenager” too. But this boy doesn’t look like a teenager. He looks like a young child. Hmm — maybe I need to reassign.

Wait — let’s list all images and labels clearly:

Images (top to bottom):
- Image 1: Toddler (small kid with bottle)
- Image 2: School-age boy — likely “child”
- Image 3: Baby in diaper — “baby”
- Image 4: Boy waving — could be “child” or “teenager”? He looks too young for teenager.
- Image 5: Old man with cane — “old age”
- Image 6: Man in suit — “adult”

Labels on right:
- teenager
- toddler
- child
- baby
- adult
- old age

So let’s match one by one:

✔ Image 1 (toddler with bottle) → toddler

✔ Image 2 (school boy) → child (since he’s not a teen yet)

✔ Image 3 (baby in diaper) → baby

✔ Image 4 (waving boy) — if Image 2 is “child”, then this might be... wait, maybe Image 4 is meant to be “teenager”? But he doesn’t look like one. Let’s think differently.

Actually, looking again — Image 4 is a boy who looks about 8–10 years old — still a child. But we only have one “child” label. So perhaps Image 2 is “teenager”? No — he has a backpack and looks younger.

Wait — maybe I miscounted. Let’s count the images: there are 6 images and 6 labels. Perfect.

Let’s assign logically:

- Smallest, in diaper → baby (Image 3)
- Just walking, holding bottle → toddler (Image 1)
- Boy with backpack → probably child (Image 2)
- Waving boy — maybe this is also child, but we can’t use it twice. Unless... perhaps the waving boy is meant to be teenager? But he doesn’t look like one.

Wait — look at Image 4 again: he’s wearing a yellow shirt and blue shorts, waving — he looks like a young boy, maybe 7–9. Still a child.

But we have a “teenager” label. Who is the teenager? Maybe Image 2 is the teenager? He’s wearing a red shirt and gray pants, carrying books — could be a middle schooler, which is early teen? But usually “teenager” starts at 13.

Alternatively, perhaps Image 4 is the teenager? He looks too young.

Wait — let’s look at the last two:

- Image 5: old man with cane → old age
- Image 6: man in suit → adult

That leaves Images 1,2,3,4 for: toddler, child, baby, teenager.

We know:
- Image 3 = baby
- Image 1 = toddler

Left: Image 2 and Image 4 for “child” and “teenager”

Image 2: boy with backpack — looks like elementary school, so “child”

Image 4: boy waving — same age? Or older? Actually, in many worksheets, the waving boy is often used for “child”, and the backpack boy might be intended as “teenager” — but that doesn’t fit.

Wait — perhaps I have it backwards. Let me check standard life cycle:

Typical order: baby → toddler → child → teenager → adult → old age

So:

- Baby: Image 3
- Toddler: Image 1
- Child: Image 4 (waving boy — young child)
- Teenager: Image 2 (backpack boy — maybe he’s meant to be older, like high school?)
- Adult: Image 6
- Old age: Image 5

Yes, that makes sense. In many educational materials, the boy with the backpack is sometimes used for “teenager” even if he looks young, because he’s carrying books and looks more independent.

So final matching:

1. Toddler (bottle kid) → toddler
2. Backpack boy → teenager (even if he looks young, it’s the best fit)
3. Baby in diaper → baby
4. Waving boy → child
5. Old man → old age
6. Man in suit → adult

But wait — the labels are listed as:

- teenager
- toddler
- child
- baby
- adult
- old age

And images are in order top to bottom.

So:

Image 1 → toddler
Image 2 → teenager
Image 3 → baby
Image 4 → child
Image 5 → old age
Image 6 → adult

Yes, that works.

Final Answer:
toddler, teenager, baby, child, old age, adult
