Problem Description:
The task involves completing a "Number Bonds" worksheet. Number bonds are pairs of numbers that add up to a given total. The goal is to fill in the missing numbers in each bond so that the sum of the two numbers below equals the number at the top.
Worksheet Layout:
The worksheet has several number bonds, each consisting of:
- A top box (the total sum)
- Two bottom boxes (the parts that add up to the total)
We need to determine the missing numbers in the top boxes for each bond.
Step-by-Step Solution:
#### First Row:
1.
Bond 1:
- Bottom numbers: 6 and 3
- Top number: \( 6 + 3 = 9 \)
- Fill in the top box with
9.
2.
Bond 2:
- Bottom numbers: 9 and 1
- Top number: \( 9 + 1 = 10 \)
- Fill in the top box with
10.
3.
Bond 3:
- Bottom numbers: 4 and 5
- Top number: \( 4 + 5 = 9 \)
- Fill in the top box with
9.
#### Second Row:
4.
Bond 4:
- Bottom numbers: 2 and 8
- Top number: \( 2 + 8 = 10 \)
- Fill in the top box with
10.
5.
Bond 5:
- Bottom numbers: 4 and 1
- Top number: \( 4 + 1 = 5 \)
- Fill in the top box with
5.
6.
Bond 6:
- Bottom numbers: 7 and 2
- Top number: \( 7 + 2 = 9 \)
- Fill in the top box with
9.
#### Third Row:
7.
Bond 7:
- Bottom numbers: 3 and 4
- Top number: \( 3 + 4 = 7 \)
- Fill in the top box with
7.
8.
Bond 8:
- Bottom numbers: 2 and 6
- Top number: \( 2 + 6 = 8 \)
- Fill in the top box with
8.
9.
Bond 9:
- Bottom numbers: 4 and 3
- Top number: \( 4 + 3 = 7 \)
- Fill in the top box with
7.
Final Answer:
The completed number bonds are as follows:
```
9 10 9
/ \ / \ / \
6 3 9 1 4 5
10 5 9
/ \ / \ / \
2 8 4 1 7 2
7 8 7
/ \ / \ / \
3 4 2 6 4 3
```
Boxed Final Answer:
\[
\boxed{9, 10, 9, 10, 5, 9, 7, 8, 7}
\]
