# Curriculum for Grade 4

As students develop a more abstract understanding of numbers, we stretch their skills in both directions - with multi-digit whole numbers as well as decimals and fractions. Students learn traditional algorithms as well as other approaches that build math flexibility and fluency. In addition to performing operations with these numbers, students learn new ways to measure, convert units, round numbers, and compare numbers. A firm understanding of place value is the common thread running through all topics.
