This Grade 5 worksheet uses multi-step real-world problems where students estimate before solving to test reasonableness. Multiple-choice items focus on order-of-magnitude reasoning for shopping totals, mileage, and recipe scaling. Fill-in problems mix decimal multiplication and division with friendly numbers. Grade 5 learners practice rounding prices, weights, and counts to confirm whether a calculated answer makes sense in everyday cooking, travel, and shopping contexts.
