Problem Description:
The task involves completing number bonds using addition and subtraction skills. Number bonds are pairs of numbers that add up to a given total. The image provides a set of number bonds with some missing values, and the numbers on the side can be used to fill in the blanks.
Solution Approach:
1.
Understand Number Bonds: A number bond is a visual representation of part-whole relationships. For example, if the total is 5, possible number bonds could be \(2 + 3\), \(1 + 4\), or \(0 + 5\).
2.
Use the Given Numbers: The numbers on the right side of the image (1, 2, 3, 4, 5) can be used to fill in the missing parts of the number bonds.
3.
Complete Each Number Bond:
- For each number bond, determine the missing part by either adding or subtracting the given numbers.
- Ensure that the sum of the two parts equals the total at the top of the bond.
Step-by-Step Solution:
#### Top Row:
1.
Bond: 3
- Given: 2
- Missing: \(3 - 2 = 1\)
- Completed: \(3 = 2 + 1\)
2.
Bond: 5
- Given: 5
- Missing: \(5 - 5 = 0\)
- Completed: \(5 = 5 + 0\)
3.
Bond: 4
- Given: 2, 2
- Both parts are already provided.
- Completed: \(4 = 2 + 2\)
#### Second Row:
4.
Bond: 5
- Given: 4
- Missing: \(5 - 4 = 1\)
- Completed: \(5 = 4 + 1\)
5.
Bond: 5
- Given: 1
- Missing: \(5 - 1 = 4\)
- Completed: \(5 = 1 + 4\)
