Number bonds of 16 addition worksheet for practicing basic math skills.

Problem Description:

The task is to fill in the missing numbers in each equation so that the sum equals 16. This involves basic addition skills and understanding number bonds.

Solution Approach:

For each equation of the form \( a + \_ = 16 \), we need to determine the missing number by subtracting \( a \) from 16. Mathematically, this can be expressed as:
\[
\text{Missing number} = 16 - a
\]

We will solve each equation step by step.

Step-by-Step Solution:

#### First Row:
1. \( 2 + \_ = 16 \)
\[
16 - 2 = 14 \quad \Rightarrow \quad 2 + 14 = 16
\]

2. \( 9 + \_ = 16 \)
\[
16 - 9 = 7 \quad \Rightarrow \quad 9 + 7 = 16
\]

3. \( 5 + \_ = 16 \)
\[
16 - 5 = 11 \quad \Rightarrow \quad 5 + 11 = 16
\]

4. \( 7 + \_ = 16 \)
\[
16 - 7 = 9 \quad \Rightarrow \quad 7 + 9 = 16
\]

#### Second Row:
5. \( 1 + \_ = 16 \)
\[
16 - 1 = 15 \quad \Rightarrow \quad 1 + 15 = 16
\]

6. \( 6 + \_ = 16 \)
\[
16 - 6 = 10 \quad \Rightarrow \quad 6 + 10 = 16
\]

7. \( 4 + \_ = 16 \)
\[
16 - 4 = 12 \quad \Rightarrow \quad 4 + 12 = 16
\]

8. \( 3 + \_ = 16 \)
\[
16 - 3 = 13 \quad \Rightarrow \quad 3 + 13 = 16
\]

#### Third Row:
9. \( 8 + \_ = 16 \)
\[
16 - 8 = 8 \quad \Rightarrow \quad 8 + 8 = 16
\]

10. \( 0 + \_ = 16 \)
\[
16 - 0 = 16 \quad \Rightarrow \quad 0 + 16 = 16
\]

11. \( 2 + \_ = 16 \)
\[
16 - 2 = 14 \quad \Rightarrow \quad 2 + 14 = 16
\]
