Math worksheet for practicing addition with regrouping.

To solve the problems in the table, we need to break down each addition problem into its tens and ones components, determine if regrouping is necessary, and then write the final sum. Let's go through each problem step by step.

---

Problem 3: \( 76 + 4 \)

1. Add the ones:
- Ones in 76: 6
- Add 4: \( 6 + 4 = 10 \)
- This results in 10 ones, which means we need to regroup 10 ones as 1 ten.

2. Add the tens:
- Tens in 76: 7
- After regrouping, add 1 ten: \( 7 + 1 = 8 \)

3. Do you regroup?: Yes

4. Write the sum:
- 8 tens and 0 ones: \( 80 \)

Answer for Problem 3:
- Tens: 8, Ones: 0
- Regroup: Yes
- Sum: 80

---

Problem 4: \( 17 + 7 \)

1. Add the ones:
- Ones in 17: 7
- Add 7: \( 7 + 7 = 14 \)
- This results in 14 ones, which means we need to regroup 10 ones as 1 ten.

2. Add the tens:
- Tens in 17: 1
- After regrouping, add 1 ten: \( 1 + 1 = 2 \)

3. Do you regroup?: Yes

4. Write the sum:
- 2 tens and 4 ones: \( 24 \)

Answer for Problem 4:
- Tens: 2, Ones: 4
- Regroup: Yes
- Sum: 24

---

Problem 5: \( 32 + 6 \)

1. Add the ones:
- Ones in 32: 2
- Add 6: \( 2 + 6 = 8 \)
- This results in 8 ones, which does not require regrouping.

2. Add the tens:
- Tens in 32: 3
- No regrouping needed: \( 3 + 0 = 3 \)

3. Do you regroup?: No

4. Write the sum:
- 3 tens and 8 ones: \( 38 \)

Answer for Problem 5:
- Tens: 3, Ones: 8
- Regroup: No
- Sum: 38

---

Problem 6: \( 59 + 5 \)

1. Add the ones:
- Ones in 59: 9
- Add 5: \( 9 + 5 = 14 \)
- This results in 14 ones, which means we need to regroup 10 ones as 1 ten.

2. Add the tens:
- Tens in 59: 5
- After regrouping, add 1 ten: \( 5 + 1 = 6 \)

3. Do you regroup?: Yes

4. Write the sum:
- 6 tens and 4 ones: \( 64 \)

Answer for Problem 6:
- Tens: 6, Ones: 4
- Regroup: Yes
- Sum: 64

---

Problem 7: \( 13 + 9 \)

1. Add the ones:
- Ones in 13: 3
- Add 9: \( 3 + 9 = 12 \)
- This results in 12 ones, which means we need to regroup 10 ones as 1 ten.

2. Add the tens:
- Tens in 13: 1
- After regrouping, add 1 ten: \( 1 + 1 = 2 \)

3. Do you regroup?: Yes

4. Write the sum:
- 2 tens and 2 ones: \( 22 \)

Answer for Problem 7:
- Tens: 2, Ones: 2
- Regroup: Yes
- Sum: 22

---

Problem 8: \( 31 + 8 \)

1. Add the ones:
- Ones in 31: 1
- Add 8: \( 1 + 8 = 9 \)
- This results in 9 ones, which does not require regrouping.

2. Add the tens:
- Tens in 31: 3
- No regrouping needed: \( 3 + 0 = 3 \)

3. Do you regroup?: No

4. Write the sum:
- 3 tens and 9 ones: \( 39 \)

Answer for Problem 8:
- Tens: 3, Ones: 9
- Regroup: No
- Sum: 39

---

Problem 9: \( 25 + 6 \)

1. Add the ones:
- Ones in 25: 5
- Add 6: \( 5 + 6 = 11 \)
- This results in 11 ones, which means we need to regroup 10 ones as 1 ten.

2. Add the tens:
- Tens in 25: 2
- After regrouping, add 1 ten: \( 2 + 1 = 3 \)

3. Do you regroup?: Yes

4. Write the sum:
- 3 tens and 1 one: \( 31 \)

Answer for Problem 9:
- Tens: 3, Ones: 1
- Regroup: Yes
- Sum: 31

---

Problem 10: \( 62 + 7 \)

1. Add the ones:
- Ones in 62: 2
- Add 7: \( 2 + 7 = 9 \)
- This results in 9 ones, which does not require regrouping.

2. Add the tens:
- Tens in 62: 6
- No regrouping needed: \( 6 + 0 = 6 \)

3. Do you regroup?: No

4. Write the sum:
- 6 tens and 9 ones: \( 69 \)

Answer for Problem 10:
- Tens: 6, Ones: 9
- Regroup: No
- Sum: 69
