This Grade 5 worksheet introduces compatible numbers for estimating quotients and applies rounding to multi-addend sums. Nine fill-in problems progress from single operations to mixed contexts including money and decimals. A matching activity links estimation prompts to their best approximations. Students learn to recognize friendly numbers that simplify division and to balance rounding directions for accurate Grade 5 estimation results.
