Problem Explanation:
The image shows a
Number Bonds Worksheet. Number bonds are a visual representation of how numbers can be split into parts. The goal is to fill in the missing parts of the number bonds so that the sum of the parts equals the total number at the top.
#### Left Side: Number Bonds with Numbers
- Each bond has a total (top number) and two parts (bottom numbers).
- The task is to find the missing part that, when added to the given part, equals the total.
#### Right Side: Number Bonds with Objects
- Each bond has a total represented by a set of objects (e.g., apples, oranges, bananas, strawberries).
- The task is to count the objects and determine how they can be split into two groups.

Solution:
####
Left Side: Number Bonds with Numbers
1.
First Row:
- Total = 10
- Part 1 = 4, Missing Part = \( 10 - 4 = 6 \)
- Part 2 = 2, Missing Part = \( 10 - 2 = 8 \)
- Part 3 = 5, Missing Part = \( 10 - 5 = 5 \)
2.
Second Row:
- Total = 10
- Part 1 = 6, Missing Part = \( 10 - 6 = 4 \)
- Part 2 = 3, Missing Part = \( 10 - 3 = 7 \)
- Part 3 = 8, Missing Part = \( 10 - 8 = 2 \)
3.
Third Row:
- Total = 10
- Part 1 = 7, Missing Part = \( 10 - 7 = 3 \)
- Part 2 = 9, Missing Part = \( 10 - 9 = 1 \)
- Part 3 = 1, Missing Part = \( 10 - 1 = 9 \)
#### Filled-in Answers for the Left Side:
- First Row: \( 6, 8, 5 \)
- Second Row: \( 4, 7, 2 \)
- Third Row: \( 3, 1, 9 \)

####
Right Side: Number Bonds with Objects
1.
First Column: Apples
- Total = 8 apples
- Split into two groups: 5 apples and 3 apples
2.
Second Column: Oranges
- Total = 7 oranges
- Split into two groups: 4 oranges and 3 oranges
3.
Third Column: Bananas
- Total = 9 bananas
- Split into two groups: 6 bananas and 3 bananas
4.
Fourth Column: Strawberries
- Total = 8 strawberries
- Split into two groups: 5 strawberries and 3 strawberries
#### Filled-in Answers for the Right Side:
- First Column: \( 5, 3 \)
- Second Column: \( 4, 3 \)
- Third Column: \( 6, 3 \)
- Fourth Column: \( 5, 3 \)
---
Final Answer:
\[
\boxed{
\text{Left Side: } 6, 8, 5; 4, 7, 2; 3, 1, 9 \\
\text{Right Side: } 5, 3; 4, 3; 6, 3; 5, 3
}
\]
