Let’s go through each problem one by one, carefully and step by step.
---
1. 40 + 2 = ?
Just add: 40 plus 2 is 42.
2. Which number is the greatest? (40, 14)
Compare 40 and 14. 40 is bigger than 14 → so 40 is the greatest.
3. What is the next number after 35, 36, 37?
This is counting up by 1s. After 37 comes 38.
4. 100 + ___ + 4 = 134
First, add what we know: 100 + 4 = 104.
Now, 104 + ? = 134 → subtract 104 from 134: 134 - 104 = 30.
So the missing number is 30.
5. A square has 3 equal sides? True/False
A square has
4 equal sides — not 3. So this is
False.
6. Subtract 50 from 100.
That means: 100 - 50 = 50.
7. What fraction is shaded?
The circle is divided into 4 equal parts. One part is shaded green.
So, 1 out of 4 → that’s
1/4.
8. In a garden, 12 butterflies were sitting on the flowers. 9 flew away. How many are left?
Start with 12, take away 9: 12 - 9 = 3.
Answer:
3 butterflies left.
9. How many vertices does this shape have?
The shape shown is a triangle. A triangle has 3 corners → those are called vertices.
So,
3 vertices.
10. Subtract 4 from 28.
That means: 28 - 4 = 24.
11. How many faces does a cube have?
Think of a dice or a box — it has front, back, top, bottom, left, right → that’s 6 faces.
Answer:
6
12. How many sides does a hexagon have?
“Hexa” means six — like hexagon = 6-sided shape.
Answer:
6
13. What time is it?
Look at the clock:
- The short hand (hour) points to 3 → so it’s 3 o’clock.
- The long hand (minute) points to 12 → that means exactly on the hour.
So, the time is
3:00.
