This worksheet involves solving number bonds, where the sum is given on the leaf, and one of the addends is provided. The task is to find the missing addend that completes the equation. Let's solve each problem step by step.
---
Problem 1:
-
Sum (Leaf): 7
-
Given Addend: 3
-
Missing Addend: ?
We need to find a number that, when added to 3, equals 7.
\[
3 + ? = 7
\]
To find the missing addend, subtract 3 from 7:
\[
? = 7 - 3 = 4
\]
So, the missing addend is
4.
---
Problem 2:
-
Sum (Leaf): 8
-
Given Addend: 4
-
Missing Addend: ?
We need to find a number that, when added to 4, equals 8.
\[
4 + ? = 8
\]
To find the missing addend, subtract 4 from 8:
\[
? = 8 - 4 = 4
\]
So, the missing addend is
4.

Problem 3:
-
Sum (Leaf): 9
-
Given Addend: 7
-
Missing Addend: ?
We need to find a number that, when added to 7, equals 9.
\[
? + 7 = 9
\]
To find the missing addend, subtract 7 from 9:
\[
? = 9 - 7 = 2
\]
So, the missing addend is
2.
---
Problem 4:
-
Sum (Leaf): 11
-
Given Addend: 2
-
Missing Addend: ?
We need to find a number that, when added to 2, equals 11.
\[
? + 2 = 11
\]
To find the missing addend, subtract 2 from 11:
\[
? = 11 - 2 = 9
\]
So, the missing addend is
9.

Final Answers:
1. Missing addend for the first problem:
4
2. Missing addend for the second problem:
4
3. Missing addend for the third problem:
2
4. Missing addend for the fourth problem:
9
Thus, the answers are:
\[
\boxed{4, 4, 2, 9}
\]
