This Grade 5 worksheet challenges learners with multi-step word problems and reasonableness judgments. Multiple choice items require selecting the most reasonable estimate from four magnitudes, while fill-in problems involve four-digit operations and decimal products. Students refine number sense by rounding decimals to the nearest whole and applying compatible numbers in division. Grade 5 estimation extends into authentic problem-solving contexts here.
