 Grade 2 Module 1: Sums and Differences to 100 Module 1 sets the foundation for students to master sums and differences to 20. Students subsequently apply these skills to fluently add onedigit to two...

 Grade 2 Module 6: Foundations of Multiplication and Division Module 6 lays the conceptual foundation for multiplication and division in Grade 3 and for the idea that numbers other than 1, 10, and 100...

 Grade 2 Module 4: Addition and Subtraction Within 200 with Word Problems to 100 In Module 4, students develop place value strategies to fluently add and subtract within 100; they represent and solve...

 Grade 2 Module 3: Place Value, Counting, and Comparison of Numbers to 1,000 In this 25day Grade 2 module, students expand their skill with and understanding of units by bundling ones, tens, and...

 Topic B focuses on spatial relationships and structuring as students organize equal groups (from Topic A) into rectangular arrays. They build small arrays (up to 5 by 5) and use repeated addition of...

 Topic C naturally follows Topic B, where students composed and manipulated the rows and columns of an array. This topic is designed to deepen students’ understanding of spatial structuring as they...

 Topic A begins at the concrete level as students use objects to create equal groups, providing a foundation for the construction of arrays in Topic B. In Lesson 1, for example, students are given 12...

 Topic C parallels Topic B, as students apply their understanding of place value strategies to the subtraction algorithm, moving from concrete to pictorial to abstract. It is important to note that...

 In Topic A, students build upon their understanding of the base ten system and their prior knowledge of place value strategies presented in Module 3. In Lesson 1, students relate 10 more and 10 less...

 In this first module of Grade 2, students make significant progress towards fluency with sums and differences within 20 (2.OA.2). Fluency, coupled with a fundamental grasp of place value, rests on...

 Now that students have practiced their kindergarten and Grade 1 skills, they are ready to become more ﬂuent with addition problems, such as 8 + 7 and 5 + 9, where they must cross the ten. In Lesson 3...

 Objective: Pair objects and skipcount to relate to even numbers.

 Objective: Investigate the pattern of even numbers: 0, 2, 4, 6, and 8 in the ones place, and relate to odd numbers.

 Objective: Use rectangular arrays to investigate odd and even numbers.

 Objective: Use math drawings to represent equal groups, and relate to repeated addition.

 Objective: Use math drawings to represent equal groups, and relate to repeated addition.

 Objective: Compose arrays from rows and columns, and count to find the total using objects.

 Objective: Decompose arrays into rows and columns, and relate to repeated addition.

 Objective: Represent arrays and distinguish rows and columns using math drawings.

 Objective: Create arrays using square tiles with gaps.

 Objective: Solve word problems involving addition of equal groups in rows and columns.

 Objective: Use square tiles to compose a rectangle, and relate to the array model.

 Objective: Use square tiles to compose a rectangle, and relate to the array model.
