Regular two-digit addition is easy—but what happens when you throw in a little rounding? In this worksheet, young addition whizzes get a run for their money as they complete multi-step addition problems that include addition with carrying, place value analysis, and rounding! For each problem, your child will solve two addition problems, round the answers to the nearest hundred, then add the rounded answers to arrive at the final answer.
