Worksheet: Subtraction for 1st Grade
We are given a series of subtraction equations with animals representing unknown numbers. We need to find the missing number (the animal) in each equation.
---
####
Step 1: Understand the format
Each problem is of the form:
>
Animal – Number = Result
We need to find the value of the
animal, which is the
missing minuend.
So, we rearrange:
>
Animal = Result + Number
---
Now, solve each problem:
1.
Turtle – 8 = 10
→ Turtle = 10 + 8 =
18
✔ Turtle =
18
2.
6 – Fox = 1
→ Fox = 6 – 1 =
5
✔ Fox =
5
3.
Dolphin – 9 = 6
→ Dolphin = 6 + 9 =
15
✔ Dolphin =
15
4.
3 – Squirrel = 2
→ Squirrel = 3 – 2 =
1
✔ Squirrel =
1
5.
Octopus – 7 = 5
→ Octopus = 5 + 7 =
12
✔ Octopus =
12
6.
8 – Bear = 2
→ Bear = 8 – 2 =
6
✔ Bear =
6

Final Answers:
| Animal | Value |
|------------|-------|
| Turtle | 18 |
| Fox | 5 |
| Dolphin | 15 |
| Squirrel | 1 |
| Octopus | 12 |
| Bear | 6 |

✔ Fill in the blanks on the right side:
- Turtle =
18
- Fox =
5
- Dolphin =
15
- Squirrel =
1
- Octopus =
12
- Bear =
6

✔ Explanation Summary:
For each problem, we used basic subtraction facts and algebraic reasoning:
- If A – B = C, then A = B + C
- If A – B = C, then B = A – C
This helps students understand inverse operations and build number sense.
