Description: Adding 3 digit numbers using compensation method. This resource helps students build mental math fluency by using the compensation method for adding 3-digit numbers. In this approach, students adjust one number to a nearby friendly number—such as rounding 198 to 200—making the addition easier to compute mentally. They then subtract the amount they added to compensate and arrive at the correct total. This strategy strengthens number sense, encourages flexible thinking, and supports efficient problem-solving when working with 3 digit numbers.
