Grade 5 students apply estimation strategies across all four operations in this challenging worksheet. Problems include rounding products, using compatible numbers for division, and estimating decimal sums and differences. The matching task challenges students to pair operations with the most reasonable estimate among choices. Money and measurement contexts reinforce why estimation matters in Grade 5 real-world problem solving, mental math practice, and answer reasonableness checks.
