1st Grade Mixed Practice Math Worksheet with Addition and Subtraction Problems

Let's solve the math problems on this 1st Grade Math Worksheet step by step. The worksheet has two sections:

---

🔹 Section 1: Find the Sum (Addition)

We’ll add each pair of numbers.

#### First Row:
- 3 + 2 = 5
- 3 + 4 = 7
- 3 + 5 = 8
- 3 + 6 = 9
- 3 + 7 = 10
- 4 + 1 = 5
- 4 + 2 = 6

#### Second Row:
- 4 + 3 = 7
- 4 + 4 = 8
- 4 + 5 = 9
- 4 + 6 = 10
- 5 + 1 = 6
- 5 + 2 = 7
- 5 + 3 = 8

#### Third Row:
- 5 + 4 = 9
- 5 + 5 = 10
- 6 + 1 = 7
- 6 + 2 = 8
- 6 + 3 = 9
- 6 + 4 = 10
- 7 + 1 = 8

🔹 Section 2: Find the Difference (Subtraction)

Now we subtract the bottom number from the top number.

#### First Row:
- 4 - 1 = 3
- 4 - 2 = 2
- 4 - 3 = 1
- 4 - 4 = 0
- 5 - 1 = 4
- 5 - 2 = 3
- 5 - 3 = 2

#### Second Row:
- 5 - 4 = 1
- 5 - 5 = 0
- 6 - 1 = 5
- 6 - 2 = 4
- 6 - 3 = 3
- 6 - 4 = 2
- 6 - 5 = 1

#### Third Row:
- 6 - 6 = 0
- 7 - 1 = 6
- 7 - 2 = 5
- 8 - 1 = 7
- 8 - 2 = 6
- 9 - 0 = 9
- 9 - 1 = 8

📝 Explanation:

This worksheet helps first graders practice basic addition and subtraction facts within 10. It reinforces number sense and mental math skills using simple, structured problems.

- Addition: Students combine two numbers to find the total.
- Subtraction: Students take away a smaller number from a larger one to find how many are left.

The number line at the top (1–10) can be used as a visual aid for counting forward (for addition) or backward (for subtraction).
