The Medium 4 worksheet introduces Grade 2 students to rounding three-digit numbers to the nearest 10 and the nearest 100 as an early taste of estimation. Second graders fill in rounded values for numbers like 47, 156, 263, and 580, then match four rounding problems to their four unique rounded answers. Helpful hints remind second graders that 5 or more rounds up and anything less than 5 rounds down for quick, accurate estimating.
