Problem Explanation:
The task involves solving "Number Bonds" for the number 10. A number bond is a pair of numbers that add up to a given total (in this case, 10). The goal is to fill in the missing numbers in each bond so that the sum of the two numbers equals 10.
Solution Approach:
For each problem, we need to determine the missing number that, when added to the given number, results in 10. This can be done using the formula:
\[
\text{Missing Number} = 10 - \text{Given Number}
\]
Step-by-Step Solution:
1.
Problem 1:
\[
10 = 4 + \_\_
\]
\[
\text{Missing Number} = 10 - 4 = 6
\]
Answer: 6
2.
Problem 2:
\[
10 = 2 + \_\_
\]
\[
\text{Missing Number} = 10 - 2 = 8
\]
Answer: 8
3.
Problem 3:
\[
10 = 1 + \_\_
\]
\[
\text{Missing Number} = 10 - 1 = 9
\]
Answer: 9
4.
Problem 4:
\[
10 = 4 + \_\_
\]
\[
\text{Missing Number} = 10 - 4 = 6
\]
Answer: 6
5.
Problem 5:
\[
10 = \_\_ + 3
\]
\[
\text{Missing Number} = 10 - 3 = 7
\]
Answer: 7
6.
Problem 6:
\[
10 = \_\_ + 9
\]
\[
\text{Missing Number} = 10 - 9 = 1
\]
Answer: 1
7.
Problem 7:
\[
10 = \_\_ + 0
\]
\[
\text{Missing Number} = 10 - 0 = 10
\]
Answer: 10
8.
Problem 8:
\[
10 = 9 + \_\_
\]
\[
\text{Missing Number} = 10 - 9 = 1
\]
Answer: 1
9.
Problem 9:
\[
10 = 0 + \_\_
\]
\[
\text{Missing Number} = 10 - 0 = 10
\]
Answer: 10
10.
Problem 10:
\[
10 = \_\_ + 1
\]
\[
\text{Missing Number} = 10 - 1 = 9
\]
Answer: 9
11.
Problem 11:
\[
10 = \_\_ + 7
\]
\[
\text{Missing Number} = 10 - 7 = 3
\]
Answer: 3
12.
Problem 12:
\[
10 = \_\_ + 3
\]
\[
\text{Missing Number} = 10 - 3 = 7
\]
Answer: 7
Final Answers:
\[
\boxed{
\begin{array}{ll}
1) & 6 \\
2) & 8 \\
3) & 9 \\
4) & 6 \\
5) & 7 \\
6) & 1 \\
7) & 10 \\
8) & 1 \\
9) & 10 \\
10) & 9 \\
11) & 3 \\
12) & 7 \\
\end{array}
}
