 Objective: Represent equal groups with tape diagrams, and relate to repeated addition.

 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 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 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...

 Module 4 culminates with Topic F, in which students think about and discuss the multiple strategies they have learned to represent and solve addition and subtraction problems. They share their...

 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...

 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...

 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...

 Objective: Use rectangular arrays to investigate odd and 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: Pair objects and skipcount to relate to even numbers.

 Objective: Relate doubles to even numbers, and write number sentences to express the sums.

 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.

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

 Objective: Create arrays using square tiles with gaps.

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

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

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

 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: Use manipulatives to create equal groups.

 Objective: Solve twostep word problems within 100.
