Module 1  Place Value and Decimal Fractions
In Module 1, students’ understanding of the patterns in the base ten system are extended from Grade 4’s work with place value of multidigit whole numbers and decimals to hundredths to the thousandths place. In Grade 5, students deepen their knowledge through a more generalized understanding of the relationships between and among adjacent places on the place value chart, e.g., 1 tenth times any digit on the place value chart moves it one place value to the right. Toward the module’s end students apply these new understandings as they reason about and perform decimal operations through the hundredths place.
