Let’s go through each question one by one and solve them carefully.
---
Question 1: What is the value of the 6 in the number 68?
- The number 68 has two digits: 6 and 8.
- The 6 is in the “tens” place.
- That means it represents 6 tens, or 60.
✔ So, the value is
60.
---
Question 2: Write down the next three numbers in this list: 8, 10, 12, 14
- Look at the pattern:
8 → +2 = 10
10 → +2 = 12
12 → +2 = 14
- So we keep adding 2.
- Next: 14 + 2 =
16
Then: 16 + 2 =
18
Then: 18 + 2 =
20
✔ Next three numbers:
16, 18, 20

**Question 3: You know that 13 + 4 = 17.
What is 17 - 13?
What is 17 - 4?**
- If 13 + 4 = 17, then subtraction undoes addition.
- 17 - 13 should give us back the other addend:
4
- And 17 - 4 should give us
13
✔ Answers:
4 and
13

Question 4: What is 3 + 6?

Question 5: Which three numbers could have a sum of 15?
- We need any three numbers that add up to 15.
- There are many correct answers! Let’s pick easy ones.
- Example: 5 + 5 + 5 = 15
✔
- Or: 4 + 5 + 6 = 15
✔
- Or: 1 + 2 + 12 = 15
✔
Since the question says “could”, any valid set works.
✔ One possible answer:
5, 5, 5 (or you can write 4, 5, 6 — both work)
---
Question 6: 3 + 3 + 3 + 3 is the same as □ × 3. What number is □?
- We’re adding 3 four times.
- That’s the same as multiplying 3 by 4.
- So: 3 + 3 + 3 + 3 = 4 × 3
✔ Therefore, □ =
4
---
Question 7: What is half of 12?
- Half means divide by 2.
- 12 ÷ 2 =
6
✔ Answer:
6
---
Question 8: What are eight 10s?
- This means: 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10
- Or: 8 × 10 =
80
✔ Answer:
80

Final Answer:
1. 60
2. 16, 18, 20
3. 4; 13
4. 9
5. 5, 5, 5 (or any three numbers that sum to 15)
