Problem Description:
The task involves filling in the missing parts of number bonds using pictures. A number bond is a visual representation that shows how numbers can be split into parts or combined to form a whole. In this case, the goal is to determine the missing parts of each number bond so that the sum equals 10.
Solution Approach:
1.
Understand Number Bonds: A number bond consists of a "whole" (the total) and its "parts." For example, if the whole is 10, the parts could be 4 and 6 because \(4 + 6 = 10\).
2.
Analyze Each Picture:
- Count the total number of items in each picture.
- Identify the given part(s) in the number bond.
- Calculate the missing part by subtracting the given part(s) from the whole (10).
Step-by-Step Solution:
####
Row 1:
-
Left Column:
- Picture: 10 lips.
- Given parts: 4 and 6.
- Total: \(4 + 6 = 10\). The number bond is correct as it sums to 10.
-
Right Column:
- Picture: 10 bows.
- Given parts: 2 and 8.
- Total: \(2 + 8 = 10\). The number bond is correct as it sums to 10.
####
Row 2:
-
Left Column:
- Picture: 10 houses.
- Given parts: 7 and 3.
- Total: \(7 + 3 = 10\). The number bond is correct as it sums to 10.
-
Right Column:
- Picture: 10 pots.
- Given parts: 1 and 9.
- Total: \(1 + 9 = 10\). The number bond is correct as it sums to 10.
####
Row 3:
-
Left Column:
- Picture: 10 hats.
- Given parts: 5 and 5.
- Total: \(5 + 5 = 10\). The number bond is correct as it sums to 10.
-
Right Column:
- Picture: 10 acorns.
- Given parts: 6 and 4.
- Total: \(6 + 4 = 10\). The number bond is correct as it sums to 10.
####
Row 4:
-
Left Column:
- Picture: 10 nests.
- Given parts: 8 and 2.
- Total: \(8 + 2 = 10\). The number bond is correct as it sums to 10.
-
Right Column:
- Picture: 10 logs.
- Given parts: 3 and 7.
- Total: \(3 + 7 = 10\). The number bond is correct as it sums to 10.
Final Answer:
All the number bonds are already filled correctly, and they all sum to 10. Therefore, no further action is needed.
\[
\boxed{
\begin{array}{cc}
4 & 6 \\
2 & 8 \\
7 & 3 \\
1 & 9 \\
5 & 5 \\
6 & 4 \\
8 & 2 \\
3 & 7 \\
\end{array}
}
\]
