Halves, Thirds, and Fourths Worksheets - Free Printable

Let’s go through each shape one by one to see if it shows halves — that means the shape is split into two equal parts.

---

✔ Circle with a straight line across the middle (horizontal)
→ Yes, this is split into two equal halves. Color it.

✔ Rectangle with a horizontal line across the middle
→ Yes, top and bottom are equal. Color it.

✘ Star
→ No lines at all — not split into any parts. Don’t color.

✔ Square with a diagonal line from corner to corner
→ This makes two triangles. Are they equal? YES — same size and shape. Color it.

✘ Hexagon with a small triangle cut off on one side
→ The two parts are NOT equal. One is tiny, one is big. Don’t color.

✔ Pentagon with a vertical line down the middle
→ Looks like it’s split evenly left and right. Yes — equal halves. Color it.

✔ Heart with a vertical line down the middle
→ Left and right sides match perfectly. Equal halves. Color it.

✔ Triangle with a vertical line from top to base
→ If it’s an isosceles or equilateral triangle, and the line goes straight down the middle, then yes — two equal halves. Color it.

✘ Oval with a slanted line
→ The line doesn’t go through the center — the two pieces are different sizes. Don’t color.

✔ Diamond (rhombus) with a vertical line
→ Split into two identical triangles. Equal halves. Color it.

Now let’s list which ones to color:

1. Circle (top center) → ✔
2. Rectangle (left column, second row) → ✔
3. Square with diagonal (center) → ✔
4. Pentagon (right column, third row) → ✔
5. Heart (bottom left) → ✔
6. Triangle (center bottom) → ✔
7. Diamond (very bottom center) → ✔

Wait — let me double-check the pentagon. Is it really split equally? Looking again — yes, the line goes from top point straight down to the middle of the base. So left and right are mirror images → equal.

And the oval — the line is tilted and not through the center → unequal → skip.

The hexagon — only a small piece cut off → definitely not half → skip.

The star — no division → skip.

So total shapes to color: 7

But wait — let’s count how many shapes there are total to make sure we didn’t miss any.

There are 10 shapes:

Row 1: circle, rectangle, star → 3
Row 2: hexagon, square, pentagon → 3
Row 3: heart, triangle, oval → 3
Row 4: diamond → 1
Total = 10

We said “don’t color”: star, hexagon, oval → 3 skipped
So 10 - 3 = 7 to color → matches.

Final check: All 7 colored shapes are truly split into two EQUAL parts.

Final Answer:
Color these 7 shapes:
- The circle (with horizontal line)
- The rectangle (with horizontal line)
- The square (with diagonal line)
- The pentagon (with vertical line)
- The heart (with vertical line)
- The triangle (with vertical line)
- The diamond (with vertical line)
