Composing and Decomposing Numbers Interactive Worksheet - Edform - Free Printable

Problem Explanation:

The task involves solving "Number Bonds" for the number 15. A number bond is a visual representation of how numbers can be split into parts. In this case, each problem shows a total (15) and one part, and the goal is to find the missing part that completes the bond.

General Formula:

For any number bond where the total is \( T \), and one part is \( P_1 \), the missing part \( P_2 \) can be found using the formula:
\[
P_2 = T - P_1
\]
Here, \( T = 15 \).

Solution for Each Problem:

#### 1)
- Total: 15
- Given part: 6
- Missing part: \( 15 - 6 = 9 \)
- Answer: \( 9 \)

#### 2)
- Total: 15
- Given part: 13
- Missing part: \( 15 - 13 = 2 \)
- Answer: \( 2 \)

#### 3)
- Total: 15
- Given part: 12
- Missing part: \( 15 - 12 = 3 \)
- Answer: \( 3 \)

#### 4)
- Total: 15
- Given part: 15
- Missing part: \( 15 - 15 = 0 \)
- Answer: \( 0 \)

#### 5)
- Total: 15
- Given part: 0
- Missing part: \( 15 - 0 = 15 \)
- Answer: \( 15 \)

#### 6)
- Total: 15
- Given part: 1
- Missing part: \( 15 - 1 = 14 \)
- Answer: \( 14 \)

#### 7)

- Missing part: \( 15 - 11 = 4 \)
- Answer: \( 4 \)

#### 9)
- Total: 15
- Given part: 11
- Missing part: \( 15 - 11 = 4 \)
- Answer: \( 4 \)

#### 10)
- Total: 15
- Given part: 2
- Missing part: \( 15 - 2 = 13 \)
- Answer: \( 13 \)

#### 11)
