Is the Integer Answer Reasonable? - Use estimation to decide whether each answer is reasonable

Uploaded by Grenda

Integer addition and subtraction problems require students to use estimation to judge whether each computed result is reasonable. The worksheet lists multiple equations with positive and negative integers, such as combining signed numbers and subtracting negative values. A separate answer key indicates for each item whether the final answer is yes (reasonable) or no (not reasonable), reinforcing estimation-based verification rather than exact calculation.
