The standard
Solve multi-step problems using addition, subtraction, multiplication, and division involving whole numbers. Use mental computation and estimation strategies to justify the reasonableness of solutions.
Element 4.NR.2.5 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Numerical Reasoning strand. It sits under standard 4.NR.2: Using part-whole strategies, solve problems involving addition and subtraction through the hundred-thousands place, as well as multiplication and division of multi-digit whole numbers presented in real-life, mathematical situations.
What students practice
Every review story combines at least two different operations with a letter for the unknown and an estimate. Test critiques ask students to judge a proposed solution.
