Symmetry Worksheet for 3rd - 4th Grade | Lesson Planet - Free Printable

Let’s go through each object one by one and check if it is symmetrical.

Symmetry means you can draw a line (usually down the middle) so that both sides are mirror images of each other — like folding paper and having both halves match perfectly.

1. Yellow book
- If we draw a vertical line down the center, the left side matches the right side. The bookmark on the bottom left breaks symmetry? Wait — actually, in most simple drawings like this, unless specified, we ignore small details like bookmarks for basic symmetry checks at Grade 3 level. But let’s be precise: the bookmark is only on the left side → not symmetric.
→ Actually, looking again: the rectangle shape is symmetric, but the bookmark sticks out only on the left. So strictly speaking, it’s NOT symmetrical.
BUT — many worksheets consider the main shape and ignore tiny asymmetries like bookmarks or handles unless they’re part of the design. Let’s think like a 3rd grader: the book looks balanced. Hmm… better to be accurate.
→ Final decision: The bookmark makes it不对称 (not symmetrical). So answer = No.

Wait — let me double-check common worksheet standards. In many Grade 3 symmetry worksheets, objects like books with spines or bookmarks are often considered symmetrical if the main body is symmetric and the detail is minor. But here, the bookmark is clearly sticking out on one side. To avoid confusion, let’s look at the others first.

Actually, let’s re-evaluate all carefully:

---

✔ Green lollipop
- Round candy on top, straight stick below.
- Vertical line down the middle: left and right sides match.
→ Symmetrical → Yes

✔ Red shopping bag
- Trapezoid shape with handle on top.
- Handle is centered. Left and right sides mirror each other.
→ Symmetrical → Yes

✔ Red bow tie
- Classic bow tie shape — two loops, centered knot.
- Vertical line down middle: perfect mirror image.
→ Symmetrical → Yes

✔ Winking emoji
- One eye open, one winking (closed), mouth curved.
- Left side ≠ right side because eyes are different.
→ Not symmetrical → No

✔ Brown megaphone
- Cone shape with handle on bottom.
- If you draw vertical line: left and right are NOT same — cone tapers to one side, handle is off-center? Actually, in this drawing, the handle is under the wide end, but the whole thing is angled? Wait — no, it’s drawn horizontally.
Looking at the image: it’s a cone pointing right, with a handle underneath near the wide end.
If you try to fold vertically — left side has narrow tip, right side has wide opening + handle. Not mirror images.
Even if you try horizontal line — top and bottom don’t match.
→ Not symmetrical → No

Now back to the book:
It’s a yellow rectangle with a smaller rectangle (label) on front, and a black bookmark hanging from bottom left corner.
The label is centered? Looks like it is. But the bookmark is ONLY on the left.
So if you fold vertically, the bookmark would have nothing to match on the right.
→ Therefore, NOT symmetrical → No

But wait — some might argue the bookmark is decorative and ignored. However, since the question says “look at the objects”, and the bookmark is drawn, we should include it.

Let’s confirm with standard answers for similar worksheets: Usually, if there’s an obvious asymmetry like a single-sided feature, it’s marked “No”.

So final decisions:

1. Book → No (bookmark breaks symmetry)
2. Lollipop → Yes
3. Shopping bag → Yes
4. Bow tie → Yes
5. Emoji → No (wink breaks symmetry)
6. Megaphone → No (shape and handle break symmetry)

Let me write them in order as shown in the worksheet:

Top row: Book, Lollipop
Middle row: Bag, Bow tie
Bottom row: Emoji, Megaphone

So answers:

Book: No
Lollipop: Yes
Bag: Yes
Bow tie: Yes
Emoji: No
Megaphone: No

Final Answer:
No, Yes, Yes, Yes, No, No
