The standard
Solve problems involving addition and subtraction of decimal numbers to the hundredths place using a variety of strategies.
Element 5.NR.4.4 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Numerical Reasoning strand. It sits under standard 5.NR.4: Read, write, and compare decimal numbers to the thousandths place, and round and perform operations with decimal numbers to the hundredths place to solve relevant, mathematical problems.
What students practice
Students combine and remove marked hundredths, align decimal places, use compensation and counting up, and explain their methods. Seven one-operation stories connect money and measurement to the calculations. Mistake critiques and inverse checks make the reasoning explicit, with a complete worked key for every practice page. Common Core crosswalk: written to Georgia's standards, these pages also practice 5.NBT.B.7 (addition and subtraction to hundredths).
