# Curriculum for Grade 5

Grade Description: Students dig more deeply into place value patterns and operations. Their understanding grows to include decimals in the hundredths and thousandths, operations with fractions and decimals, multi-digit multiplication and division with remainders, area models, properties of multiplication and division, estimation, and measuring volume.
