Math worksheet for practicing subtraction using near doubles facts.

You're working on a math worksheet titled “Subtract Using Near Doubles” from SplashLearn. The goal is to use known subtraction facts (called “doubles” or “near doubles”) to solve new, slightly harder problems.

🔍 What are “Near Doubles”?

A double is when you subtract a number from itself or from a number close to it — like `4 - 2 = 2`, `8 - 4 = 4`, or `10 - 5 = 5`. These are easy because they’re half of the first number.

A near double is when one number is *close* to being half of the other — for example, `14 - 7 = 7` (which is a double), and then `15 - 7` is a near double because 7 is almost half of 15.

The trick is: Use the double fact you know, then adjust by 1 or 2.

✔ Let’s solve each problem using this strategy:

---

#### 1. 11 - 5 = ?

Think:
We know `10 - 5 = 5` (from the top row).
11 is 1 more than 10 → so the answer is 1 more than 5 → 6

✔ Answer: 6

---

#### 2. 7 - 4 = ?

Think:
We know `8 - 4 = 4` (given).
7 is 1 less than 8 → so the answer is 1 less than 4 → 3

✔ Answer: 3

*(Alternatively: 4 + 3 = 7 → so 7 - 4 = 3)*

---

#### 3. 15 - 7 = ?

Think:
We know `14 - 7 = 7` (given).
15 is 1 more than 14 → so the answer is 1 more than 7 → 8

✔ Answer: 8

---

#### 4. 5 - 2 = ?

Think:
We know `4 - 2 = 2` (given).
5 is 1 more than 4 → so the answer is 1 more than 2 → 3

✔ Answer: 3

---

#### 5. 17 - 8 = ?

Think:
We know `16 - 8 = 8` (given).
17 is 1 more than 16 → so the answer is 1 more than 8 → 9

✔ Answer: 9

---

#### 6. 9 - 5 = ?

Think:
We know `10 - 5 = 5` (given).
9 is 1 less than 10 → so the answer is 1 less than 5 → 4

✔ Answer: 4

---

#### 7. 17 - 9 = ?

Think:
We know `18 - 9 = 9` (given).
17 is 1 less than 18 → so the answer is 1 less than 9 → 8

✔ Answer: 8

---

#### 8. 15 - 8 = ?

Think:
We know `16 - 8 = 8` (given).
15 is 1 less than 16 → so the answer is 1 less than 8 → 7

✔ Answer: 7

📝 Final Answers (in order):

```
11 - 5 = 6
7 - 4 = 3
15 - 7 = 8
5 - 2 = 3
17 - 8 = 9
9 - 5 = 4
17 - 9 = 8
15 - 8 = 7
```

💡 Teaching Tip:

This strategy helps kids build mental math fluency. Instead of memorizing every single subtraction fact, they learn to relate new problems to ones they already know — building confidence and flexibility in thinking!
