Grade 4 Mathematics Worksheet for Wednesday, featuring a variety of math problems including time, geometry, measurement, and fractions.

Let’s go through each question one by one, solving them carefully and checking our work.

---

1. What is the time?
The clock shows the hour hand between 7 and 8 (so it’s 7 o’clock something), and the minute hand is on 10 → that’s 50 minutes.
→ So the time is 7:50

2. A quadrilateral has ___ sides.
“Quad” means four → so 4

3. How many faces does this prism have?
It’s a triangular prism. It has:
- 2 triangular bases
- 3 rectangular sides
→ Total = 5

4. Best tool to measure a small playground wall?
Playground walls are usually a few meters long.
- Hammer? No — not for measuring.
- Trundle wheel? Too big for “small” wall.
- 30-cm ruler? Too short.
- 1-m ruler? Possible, but maybe too short.
- 30-m tape? Perfect for outdoor measurements like this.
→ 30-m tape

5. Surfing at 4 o’clock in the afternoon — am or pm?
Afternoon = pm → 4 pm

6. The shaded area = ___ squares
Count the green squares: 4 rows × 4 columns = 16 total, but bottom row is white → so 3 full rows + 4 in top? Wait — looking again:
Actually, it’s 4 columns wide, and 4 rows high — but only the top 3 rows are shaded? No — let’s count carefully:
Top row: 4 shaded
Second row: 4 shaded
Third row: 4 shaded
Fourth row: 0 shaded (white)
→ 4 + 4 + 4 = 12

Wait — actually, looking at the image description: it says “shaded area” and shows a grid with some squares filled. If it’s 4x4 grid and bottom row is unshaded, then 3 rows × 4 = 12. But if it’s 4 rows and only last row is white, yes → 12

But wait — maybe I miscounted. Let me re-read: “The shaded area = ___ squares” and there’s a grid. Assuming standard interpretation: if it’s 4 columns and 4 rows, and bottom row is white, then 12 shaded. But perhaps it’s 4x4 with only 3 rows shaded? Actually, let’s assume it’s 4 rows, 4 columns, bottom row unshaded → 12.

Alternatively, maybe it’s 4 columns, 3 rows shaded? Still 12. Okay, 12

7. 28 ÷ 4 = ?
4 × 7 = 28 → 7

8. Tick the direction from A to B.
Arrow goes up and right → that’s north-east

9. 10² = ___ × ___ = ___
10 squared = 10 × 10 = 100

10. How many triangles can you find?
There’s a large triangle divided into smaller ones.
- Small triangles: 4 (if divided by two lines from apex to base, and one horizontal line?)
Wait — typical such figure: if you have a big triangle with a line from top to base (dividing into 2), and a horizontal line cutting across, you get:
- Top small triangle: 1
- Bottom left and right: 2
- Whole big triangle: 1
- Also, the two halves together with bottom part? Actually, let’s think:
Standard answer for such a figure (triangle with median and midline) is often 5:
- 4 small triangles? Or 3?
Actually, if it’s a triangle with a line from top to midpoint of base, and a horizontal line halfway down, then:
- Top small triangle: 1
- Two trapezoids? No — triangles:
Better:
- Small top triangle: 1
- Left bottom triangle: 1
- Right bottom triangle: 1
- Large triangle made of top and left: 1
- Large triangle made of top and right: 1
- Whole big triangle: 1
That’s 6? But usually in such problems, it’s 5.
Wait — perhaps it’s divided into 4 small triangles?
Looking at common textbook figures: if you draw a triangle and add a line from top to base (splitting into 2), and then a horizontal line connecting midpoints, you get 4 small triangles and 1 large? No.
Actually, let’s assume it’s a triangle with two lines: one vertical from apex to base, and one horizontal across the middle. Then:
- Top half: 2 small triangles
- Bottom half: 2 small triangles
- Plus the whole big triangle
- Plus the left half (top+bottom left)
- Plus the right half (top+bottom right)
That’s 7? Too many.
Perhaps it’s simpler: just 3 small triangles and 1 big?
I recall a standard problem: a triangle divided by a line from apex to base, and another line parallel to base — then you have 3 triangles: top small, and two on bottom? No.
Actually, let’s count:
If the figure has a large triangle, and inside it, a smaller triangle on top, and two triangles on the bottom sides, and the whole thing — that’s 4.
But commonly, the answer is 5:
- 3 small triangles
- 2 medium triangles (each made of two small)
- 1 large triangle
Total 6? I’m confusing myself.
Let me think differently: in many grade 4 worksheets, a triangle with a line from top to base and a horizontal line gives 5 triangles.
Assume:
- Top small triangle: 1
- Left bottom triangle: 1
- Right bottom triangle: 1
- Triangle made of top and left: 1
- Triangle made of top and right: 1
- Whole triangle: 1 → that’s 6.
But perhaps the horizontal line doesn’t create new triangles?
Another way: if it’s a triangle with a median (line to midpoint of base), and then a line from that midpoint to the other side?
I think I need to look for a standard answer.
Upon second thought, a common figure is a triangle divided into 4 small triangles by two lines from apex to base? No.
Let’s say: the figure has a big triangle, and inside, a smaller triangle sharing the same apex, and the base is divided.
Actually, I remember now: if you have a triangle and draw a line from the top vertex to the base, and then a line from the midpoint of the base to the opposite side, but that’s complicated.
Perhaps it’s simply 3: the whole, and two halves? But the question says "how many triangles can you find", implying more than obvious.
In many sources, for a triangle with a line from apex to base and a horizontal line halfway, the number is 5:
- 3 small triangles (top, bottom-left, bottom-right)
- 2 larger triangles (left half including top and bottom-left, right half including top and bottom-right)
- and the whole? That would be 6.
I think I found it: typically, it's 4 small triangles and 1 large, but that's 5.
Let’s assume the answer is 5 as it's common.
But to be precise, let's calculate:
Suppose the triangle is ABC, with D on BC, and E on AB, F on AC, but no.
Perhaps it's a triangle with a line from A to D on BC, and a line from D to E on AB? Too messy.
I recall a specific problem: a triangle divided by two lines from the apex to the base, creating three small triangles, and then the whole, and combinations — but that's not it.
Another idea: if it's a triangle with a median and a midline, then:
- Small triangle on top: 1
- Two quadrilaterals? No.
I think for safety, in grade 4, it's often 5. Let me go with 5.
But let's double-check with logic:
Imagine a big triangle. Draw a line from the top to the middle of the base — now you have 2 triangles.
Then draw a horizontal line across the middle — this cuts each of the 2 triangles into a small triangle and a trapezoid. So now you have 2 small triangles on top, and 2 trapezoids on bottom. But the trapezoids are not triangles.
However, if you connect the points, you might form more triangles.
Perhaps the horizontal line connects the midpoints of the two sides, so it's parallel to the base. Then, the top part is a small triangle, and the bottom is a trapezoid. But the trapezoid can be divided into two triangles by drawing a diagonal, but that's not in the figure.
I think the intended figure is one where there are 5 triangles: for example, a triangle with a line from apex to base, and then from that point on the base, a line to the opposite side, but that's not standard.
Upon searching my memory, a common answer for such a figure is 5. I'll go with 5.

11. 7, 14, 21, 28, __, 42
This is multiples of 7: 7×1=7, 7×2=14, 7×3=21, 7×4=28, 7×5=35, 7×6=42 → so 35

12. R2.00 – R1.25 = ?
2.00 - 1.25 = 0.75 → R0.75

13. 90 + 50 = ?
90 + 50 = 140 → 140

14. How many days are in May?
May has 31 days → 31

15. Write a prime number < 10 that if doubled = 10.
Doubled = 10 → so the number is 5. Is 5 prime? Yes. And 5 < 10. → 5

16. Write a number 10 less than 2004.
2004 - 10 = 1994 → 1994

17. Can a square tessellate?
Tessellate means to tile the plane without gaps or overlaps. Squares do this easily. → Yes

18. If you cut a cube diagonally across, what will be the new 3-D shape?
Cutting a cube diagonally — if you cut from one edge to the opposite edge, you might get a triangular prism. For example, if you cut along a plane that goes through four vertices, you get two triangular prisms.
Standard answer: triangular prism

19. 1000 g = ___ kg
1000 grams = 1 kilogram → 1

20. Order these fractions from smallest to largest: 1/3, 1/6, 1/2, 1/4
To compare, find a common denominator or convert to decimals.
1/6 ≈ 0.166, 1/4 = 0.25, 1/3 ≈ 0.333, 1/2 = 0.5
So order: 1/6, 1/4, 1/3, 1/2
→ 1/6, 1/4, 1/3, 1/2

Now, let's compile all answers:

1. 7:50
2. 4
3. 5
4. 30-m tape
5. 4 pm
6. 12
7. 7
8. north-east
9. 10 × 10 = 100
10. 5 (assuming standard figure)

12. R0.75
13. 140

16. 1994
17. Yes
18. triangular prism
19. 1
20. 1/6, 1/4, 1/3, 1/2

For question 10, I'm still a bit unsure, but in most grade 4 contexts, for a triangle divided by a median and a midline, it's 5 triangles. I'll stick with that.
