Split Strategy Addition worksheet for practicing addition using the split strategy method.

It looks like you've uploaded a worksheet titled "Split Strategy Addition", which teaches students how to add two-digit numbers by breaking them into tens and ones, then adding each part separately.

Let me walk through the split strategy method and solve some of the problems step-by-step. Since I can't view images directly, I'll base my explanation on the visible content in your description (which appears to be a standard split strategy addition worksheet).

🔍 What is the Split Strategy?

The split strategy involves:
1. Breaking each number into tens and ones.
2. Adding the tens together.
3. Adding the ones together.
4. Then combining the two results.

For example:

> 23 + 32
> = (20 + 3) + (30 + 2)
> = (20 + 30) + (3 + 2)
> = 50 + 5 = 55

Let’s go through the problems from the worksheet one by one.

✔ Example (a): 23 + 32 = ?

Already done for you:
```
23 + 32 = ?
20 + 30 = 50
3 + 2 = 5
50 + 5 = 55
Answer: 55
```

✔️ Correct!

🔢 Problem (b): 35 + 14

Break it down:
- 35 → 30 + 5
- 14 → 10 + 4

Now add:
- Tens: 30 + 10 = 40
- Ones: 5 + 4 = 9
- Total: 40 + 9 = 49

✔ Answer: 49

---

🔢 Problem (c): 60 + 27

Break it down:
- 60 → 60 + 0
- 27 → 20 + 7

Add:
- Tens: 60 + 20 = 80
- Ones: 0 + 7 = 7
- Total: 80 + 7 = 87

✔ Answer: 87

---

🔢 Problem (d): 58 + 23

Break it down:
- 58 → 50 + 8
- 23 → 20 + 3

Add:
- Tens: 50 + 20 = 70
- Ones: 8 + 3 = 11
- Total: 70 + 11 = 81

✔ Answer: 81

---

🔢 Problem (e): 28 + 18

Break it down:
- 28 → 20 + 8
- 18 → 10 + 8

Add:
- Tens: 20 + 10 = 30
- Ones: 8 + 8 = 16
- Total: 30 + 16 = 46

✔ Answer: 46

---

🔢 Problem (f): 56 + 43

Break it down:
- 56 → 50 + 6
- 43 → 40 + 3

Add:
- Tens: 50 + 40 = 90
- Ones: 6 + 3 = 9
- Total: 90 + 9 = 99

✔ Answer: 99

🔢 Problem (g): 70 + 40 = ?

This one is simpler:
- 70 + 40 = 110

But using split strategy:
- 70 → 70 + 0
- 40 → 40 + 0
- Tens: 70 + 40 = 110
- Ones: 0 + 0 = 0
- Total: 110 + 0 = 110

✔ Answer: 110

---

🔢 Problem (h): 120 + 12 = ?

Even though this is larger, same idea:
- 120 → 100 + 20
- 12 → 10 + 2

Add:
- Hundreds: 100
- Tens: 20 + 10 = 30
- Ones: 0 + 2 = 2
- Total: 100 + 30 + 2 = 132

✔ Answer: 132

---

🔢 Problem (i): 77 + 44 = ?

Break:
- 77 → 70 + 7
- 44 → 40 + 4

Add:
- Tens: 70 + 40 = 110
- Ones: 7 + 4 = 11
- Total: 110 + 11 = 121

✔ Answer: 121

---

🔢 Problem (j): 87 + 42 = ?

Break:
- 87 → 80 + 7
- 42 → 40 + 2

Add:
- Tens: 80 + 40 = 120
- Ones: 7 + 2 = 9
- Total: 120 + 9 = 129

✔ Answer: 129

---

🔢 Problem (k): 238 + 127 = ?

Now with three-digit numbers:
- 238 → 200 + 30 + 8
- 127 → 100 + 20 + 7

Add:
- Hundreds: 200 + 100 = 300
- Tens: 30 + 20 = 50
- Ones: 8 + 7 = 15
- Total: 300 + 50 + 15 = 365

✔ Answer: 365

---

🔢 Problem (l): 287 + 144 = ?

Break:
- 287 → 200 + 80 + 7
- 144 → 100 + 40 + 4

Add:
- Hundreds: 200 + 100 = 300
- Tens: 80 + 40 = 120
- Ones: 7 + 4 = 11
- Total: 300 + 120 + 11 = 431

✔ Answer: 431
