Number Bonds Worksheets Printable, Domino Number Bond Math ... - Free Printable

To solve these "Domino Number Bonds," we need to understand how the diagram works.

1. Look at the domino: Count the dots on the top half and the dots on the bottom half.
2. Find the total: Add the top number and the bottom number together. This total goes in the middle circle (the one connected to both other circles).
3. Fill in the parts: The two outer circles are just the individual numbers from the domino. One gets the top number, and the other gets the bottom number. It doesn't matter which outer circle gets which number, as long as the middle one is the sum.

Let's go through each problem step-by-step:

Problem 1:
* Top dots: 6
* Bottom dots: 3
* Middle (Sum): $6 + 3 = 9$
* Outer circles: 6 and 3

Problem 2:
* Top dots: 2
* Bottom dots: 5
* Middle (Sum): $2 + 5 = 7$
* Outer circles: 2 and 5

Problem 3:
* Top dots: 4
* Bottom dots: 4
* Middle (Sum): $4 + 4 = 8$
* Outer circles: 4 and 4

Problem 4:
* Top dots: 6
* Bottom dots: 4
* Middle (Sum): $6 + 4 = 10$
* Outer circles: 6 and 4

Problem 5:
* Top dots: 5
* Bottom dots: 3
* Middle (Sum): $5 + 3 = 8$
* Outer circles: 5 and 3

Problem 6:
* Top dots: 1
* Bottom dots: 5
* Middle (Sum): $1 + 5 = 6$
* Outer circles: 1 and 5

Problem 7:
* Top dots: 2
* Bottom dots: 4
* Middle (Sum): $2 + 4 = 6$
* Outer circles: 2 and 4

Problem 8:
* Top dots: 4
* Bottom dots: 5
* Middle (Sum): $4 + 5 = 9$
* Outer circles: 4 and 5

Final Answer:
1. Middle: 9, Outers: 6, 3
2. Middle: 7, Outers: 2, 5
3. Middle: 8, Outers: 4, 4
4. Middle: 10, Outers: 6, 4
5. Middle: 8, Outers: 5, 3
6. Middle: 6, Outers: 1, 5
7. Middle: 6, Outers: 2, 4
8. Middle: 9, Outers: 4, 5
