Let’s solve each fact family step by step. A fact family uses the same three numbers to make addition and subtraction sentences that are true.

Top Left Barn (Numbers: 10, 7, 3)
We know:
- 7 + 3 = 10
- 3 + 7 = 10
- 10 - 7 = 3
- 10 - 3 = 7
So fill in:
□ + 3 = □ →
7 + 3 = 10
□ + 7 = □ →
3 + 7 = 10
□ - 3 = □ →
10 - 3 = 7
10 - □ = □ →
10 - 7 = 3

Top Right Barn (Numbers: 9, 5, 4)
We know:
- 5 + 4 = 9
- 4 + 5 = 9
- 9 - 5 = 4
- 9 - 4 = 5
So fill in:
□ + □ = 9 →
5 + 4 = 9
□ + 5 = □ →
4 + 5 = 9
9 - □ = □ →
9 - 5 = 4
9 - 4 = □ →
9 - 4 = 5
---
Bottom Left Barn (Numbers: 13, 8, 5)
We know:
- 8 + 5 = 13
- 5 + 8 = 13
- 13 - 8 = 5
- 13 - 5 = 8
So fill in:
5 + □ = □ →
5 + 8 = 13
□ + □ = 13 →
8 + 5 = 13
□ - 8 = □ →
13 - 8 = 5
13 - □ = □ →
13 - 5 = 8
---
Bottom Right Barn (Numbers: 11, 6, 5)
We know:
- 6 + 5 = 11
- 5 + 6 = 11
- 11 - 6 = 5
- 11 - 5 = 6
So fill in:
□ + □ = □ →
6 + 5 = 11
□ + □ = □ →
5 + 6 = 11
□ - □ = □ →
11 - 6 = 5
□ - □ = □ →
11 - 5 = 6

Final Answer:
Top Left Barn:
7 + 3 = 10
3 + 7 = 10
10 - 3 = 7
10 - 7 = 3
Top Right Barn:
5 + 4 = 9
4 + 5 = 9
9 - 5 = 4
9 - 4 = 5
Bottom Left Barn:
5 + 8 = 13
8 + 5 = 13
13 - 8 = 5
13 - 5 = 8
Bottom Right Barn:
6 + 5 = 11
5 + 6 = 11
11 - 6 = 5
11 - 5 = 6
