Adding using the “Compensation” method ‼️We can’t change one addend in a problem without “compensating” and changing the other addend. 🤔 I’ve been thinking about what makes this different from “making ten”, and I THINK it is that this strategy is more general. For example 12 18 = (12 3) (18 - 3) = 15 15 = 30 🌟 We weren’t “making ten” because we weren’t aiming for 10 or 20 (but that also would have worked!) #addition #mathtricks #homeschoolers
