"Order by Size" worksheet for preschoolers, featuring six groups of objects to be arranged from smallest to largest.

To solve this worksheet, we need to look at each group of three pictures and decide how to order them by size. Usually, "order by size" means putting them in a line from smallest to largest (or sometimes largest to smallest). Let’s check the pattern in each row.

We’ll go row by row, left to right, top to bottom.

---

Row 1, Left: Fish
- There are three fish: one big, one medium, one small.
- From left to right in the picture: Big → Medium → Small
- But we want to order them by size — let’s assume smallest to largest unless told otherwise.
- So correct order should be: Small → Medium → Big
- That means the boxes under them should get numbers:
- First box (under big fish) = 3 (largest)
- Second box (under medium fish) = 2
- Third box (under small fish) = 1 (smallest)
→ Wait — actually, maybe we’re supposed to write 1, 2, 3 in the boxes to show the order? Yes! Typically in these worksheets, you write “1” under the smallest, “2” under the next, “3” under the largest.

Let me confirm with another row.

Row 1, Right: Rabbits
- Three rabbits: small, medium, large (left to right in image: small → medium → large)
- If we number them 1, 2, 3 for smallest to largest:
- Left rabbit (small) = 1
- Middle rabbit (medium) = 2
- Right rabbit (large) = 3
That makes sense.

So rule: In each set of 3, write 1 under the smallest, 2 under the middle-sized, 3 under the largest.

Now apply that to all rows.

Row 2, Left: Apples
Image shows: Medium apple, Small apple, Large apple (left to right)
So:
- Left (medium) → should be 2
- Middle (small) → should be 1
- Right (large) → should be 3

Boxes: [2] [1] [3]

Row 2, Right: Lollipops
Image: Medium lollipop, Small lollipop, Large lollipop (left to right)
Wait — let’s look carefully:
Actually, from left to right:
- First: medium-sized round top
- Second: smaller round top
- Third: largest round top

So:
- Left = medium → 2
- Middle = small → 1
- Right = large → 3

Boxes: [2] [1] [3]

But wait — is the stick length part of size? Probably not — we go by the head/candy part. The third one has the biggest circle on top.

Yes.

Row 3, Left: Dogs
Image: Small dog, Large dog, Medium dog (left to right)
So:
- Left (small) → 1
- Middle (large) → 3
- Right (medium) → 2

Boxes: [1] [3] [2]

---

Row 3, Right: Leaves
Image: Medium leaf, Large leaf, Small leaf (left to right)
Check sizes:
- Left: medium
- Middle: largest
- Right: smallest

So:
- Left → 2
- Middle → 3
- Right → 1

Boxes: [2] [3] [1]

---

Now let’s compile all answers row by row, left column then right column.

The worksheet has 6 sections:

Top-left: Fish → [3] [2] [1] ? Wait no — earlier I said for fish: left is big, middle medium, right small → so to order smallest to largest, we assign:
- Under big fish (left): 3
- Under medium fish (middle): 2
- Under small fish (right): 1

But that would mean writing 3, 2, 1 in the boxes — which is ordering from largest to smallest? Hmm.

Wait — maybe the instruction is to order them *as they appear*? No, the title is “Order by Size”, and typically you re-order mentally and label positions.

Standard practice: You look at the three items, find which is smallest, put “1” under it; next smallest “2”; largest “3”.

So regardless of their position in the row, you label based on size.

For Fish:
Positions: Left=Big, Middle=Medium, Right=Small
So:
- Smallest is Right → put 1 under right
- Middle is Middle → put 2 under middle
- Largest is Left → put 3 under left

So boxes: Left=3, Middle=2, Right=1 → [3] [2] [1]

Similarly, Rabbits:
Left=Small → 1
Middle=Medium → 2
Right=Large → 3 → [1] [2] [3]

Apples:
Left=Medium → 2
Middle=Small → 1
Right=Large → 3 → [2] [1] [3]

Lollipops:
Left=Medium → 2
Middle=Small → 1
Right=Large → 3 → [2] [1] [3]

Dogs:
Left=Small → 1
Middle=Large → 3
Right=Medium → 2 → [1] [3] [2]

Leaves:
Left=Medium → 2
Middle=Large → 3
Right=Small → 1 → [2] [3] [1]

Now, to present final answer clearly.

Since the worksheet has 6 groups, and each has 3 boxes, we can list the numbers to write in each box, going row by row, left to right within each row.

Final Answer:

Fish: 3, 2, 1
Rabbits: 1, 2, 3
Apples: 2, 1, 3
Lollipops: 2, 1, 3
Dogs: 1, 3, 2
Leaves: 2, 3, 1

But since the user just wants the final answer filled in, and there's no specific format requested beyond "final correct answer", I'll write it as the sequence of numbers for each group in order.

Alternatively, perhaps list them as pairs per section.

But simplest: Provide the numbers to write in the boxes, in the order they appear on the page (top to bottom, left to right sections).

Section 1 (Fish): boxes left to right → 3, 2, 1
Section 2 (Rabbits): 1, 2, 3
Section 3 (Apples): 2, 1, 3
Section 4 (Lollipops): 2, 1, 3
Section 5 (Dogs): 1, 3, 2
Section 6 (Leaves): 2, 3, 1

I think that’s accurate.

Double-check Leaves:
Image: first leaf (left) is medium size → should be 2
Second leaf (middle) is largest → 3
Third leaf (right) is smallest → 1
Yes → [2, 3, 1]

All good.

Final Answer:
Fish: 3, 2, 1
Rabbits: 1, 2, 3
Apples: 2, 1, 3
Lollipops: 2, 1, 3
Dogs: 1, 3, 2
Leaves: 2, 3, 1
