Math worksheet titled "Number Sentences - Practice the Skill" featuring word problems for students to solve and write number sentences.

You’ve uploaded a worksheet titled “Number Sentences – Practice the Skill”. This is a math practice sheet for early elementary students (likely 1st or 2nd grade) focusing on writing and solving simple addition and subtraction number sentences based on word problems.

✔ Here’s how to solve each problem:

We’ll go one by one, interpret the story, write the correct number sentence, and solve it.

---

#### Problem 1:
> There are 3 tea chests. One of the 3 chests has 5 teabags. How many teabags are there in total?

- Interpretation: Only ONE chest has 5 teabags. The other two chests have 0 (not mentioned, so assume empty).
- Number Sentence: `5 + 0 + 0 = 5`
- Answer: 5

✔ Fill in: `5 + 0 + 0 = 5`

---

#### Problem 2:
> There are 8 cans of soup. 4 of them are spicy. How many are not spicy?

- Interpretation: Total cans = 8. Spicy = 4. So non-spicy = 8 - 4.
- Number Sentence: `8 - 4 = 4`
- Answer: 4

✔ Fill in: `8 - 4 = 4`

---

#### Problem 3:
> There are 9 eggs in a basket. Mary 3 of them are rotten. How many are there that are good?

- Interpretation: Total eggs = 9. Rotten = 3. Good = 9 - 3.
- Number Sentence: `9 - 3 = 6`
- Answer: 6

✔ Fill in: `9 - 3 = 6`

---

#### Problem 4:
> There are 5 books. 2 were placed on shelf 2. How many are on shelf 1?

- Interpretation: Total books = 5. Shelf 2 has 2 → Shelf 1 has 5 - 2.
- Number Sentence: `5 - 2 = 3`
- Answer: 3

✔ Fill in: `5 - 2 = 3`

---

#### Problem 5:
> Number line: 3 steps right, then 2 steps left. Where do you end up?

- Interpretation: Start at 0. Go right 3 → +3. Then left 2 → -2.
- Number Sentence: `3 - 2 = 1` OR `0 + 3 - 2 = 1`
- Answer: 1

✔ Fill in: `3 - 2 = 1`

*(Note: The worksheet says “Number line 3 steps right, then 2 steps left.” It implies starting from 0.)*

---

#### Problem 6:
> Sam has 6 cookies. He ate 3. How many does he have now?

- Interpretation: Start with 6, eat 3 → subtract.
- Number Sentence: `6 - 3 = 3`
- Answer: 3

✔ Fill in: `6 - 3 = 3`

---

#### Problem 7:
> There are 4 children in a room. Mary put 3 more in. How many are there now?

- Interpretation: Start with 4, add 3 more.
- Number Sentence: `4 + 3 = 7`
- Answer: 7

✔ Fill in: `4 + 3 = 7`

---

#### Problem 8:
> Johnny has 7 tickets and gets 3 more. How many does he have now?

- Interpretation: 7 + 3.
- Number Sentence: `7 + 3 = 10`
- Answer: 10

✔ Fill in: `7 + 3 = 10`

---

#### Problem 9:
> He has 5 pair of shoes. One of his 5 pairs takes 2 pairs. How many does he have now?

⚠️ This problem has a typo!
It says: *“One of his 5 pairs takes 2 pairs.”* — That doesn’t make sense.

Likely meant: “He gives away 2 pairs.” or “He loses 2 pairs.”

Assuming it means he removes or gives away 2 pairs from 5:

- Number Sentence: `5 - 2 = 3`
- Answer: 3

✔ Fill in: `5 - 2 = 3`

*(If the original wording was intentional, it’s confusing — but in context of the worksheet, subtraction is expected.)*

---

#### Problem 10:
> There are 9 bikes. 3 of them are red. How many are blue?

- Interpretation: Total = 9. Red = 3. Blue = 9 - 3.
- Number Sentence: `9 - 3 = 6`
- Answer: 6

✔ Fill in: `9 - 3 = 6`

## 🎯 Final Answer Key:

| Problem | Number Sentence | Answer |
|---------|----------------------|--------|
| 1 | 5 + 0 + 0 = 5 | 5 |
| 2 | 8 - 4 = 4 | 4 |
| 3 | 9 - 3 = 6 | 6 |
| 4 | 5 - 2 = 3 | 3 |
| 5 | 3 - 2 = 1 | 1 |
| 6 | 6 - 3 = 3 | 3 |
| 7 | 4 + 3 = 7 | 7 |
| 8 | 7 + 3 = 10 | 10 |
| 9 | 5 - 2 = 3 | 3 |
| 10 | 9 - 3 = 6 | 6 |

## 💡 Teaching Tip:
This worksheet teaches translating word problems into number sentences — a foundational skill for algebra. Emphasize:
- Identifying total vs. parts
- When to add (combine) vs. subtract (take away)
- Reading carefully (especially for tricky wording like #9)
