The standard
Fluently add and subtract multi-digit numbers to solve practical, mathematical problems using place value understanding, properties of operations, and relationships between operations.
Element 4.NR.2.1 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
Students choose a place-value strategy for five-digit sums and differences and find a missing addend. Each sum or minuend is above 10,000.
