Addition using compensation is a strategy to make numbers easier to add. You adjust one number to a nearby "friendly" number, then compensate by adjusting the other number to keep the total the same.
This strategy uses mental math by rounding numbers to make addition faster and simpler.
To use compensation, change one number to a friendlier number (like a multiple of 10 or 100), then adjust the other number so the total does not change.
The total stays the same because you increased one number and decreased the other by the same amount.
Compensation makes addition easier by turning numbers into friendly numbers, which are simpler to work with mentally.
This method avoids regrouping and builds number sense by using place value and relationships between numbers.
You can also apply compensation to solve real-life problems that involve adding larger numbers.
Compensation is useful when one number is close to a multiple of 10 or 100.
