Grade 5 Module 1: Place Value and Decimal Fractions

Grade 4 Module 1: Place Value, Rounding, and Algorithms for Addition and Subtraction

Grade 3 Module 1: Properties of Multiplication and Division and Solving Problems with Units of 2–5 and 10

This 25-day module begins the year by building on students’ fluency with addition and knowledge of arrays.

Grade 2 Module 2: Relate Addition and Subtraction to Length

In this 12-day Grade 2 module, students engage in activities designed to deepen their conceptual understanding of measurement and to relate addition and subtraction to length.  Their work in Module 2 is exclusively with metric units in order to support place value concepts.  Customary units will be introduced in Module 7.

Grade 2 Module 1: Sums and Differences to 20

Module 1 sets the foundation for students to master the sums and differences to 20 and to  subsequently apply these skills to fluently add one-digit to two-digit numbers at least through 100 using place value understandings, properties of operations and the relationship between addition and subtraction.

Grade 1 Module 1: Sums and Differences to 10

In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 as they are presented with opportunities intended to advance them from counting all to counting on which leads many students then to decomposing and composing addends and total amounts.
