Module 1: Sums and Differences to 20 
Here is a video which helps explain what we are doing in 2nd grade in Module 1. 
Module 1 sets the foundation for students to master the sums and differences to 20 and to subsequently apply these skills to fluently add onedigit to twodigit numbers at least through 100 using place value understandings, properties of operations and the relationship between addition and subtraction.
Topic A: 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 three essential skills: 1) knowing number bonds of ten, 2) adding ten and some ones, and 3) the number bonds (pairs) of numbers through ten.

Lesson 2: Make number bonds through ten with a subtraction focus and apply to onestep word problems.

Topic B: 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.

Topic C: In Topic C, students revisit their addition and subtraction skills, practicing with larger numbers up to 100. Throughout this topic, students use tenframes and number bonds to add and subtract using the structure of ten.
Lesson 6: Add and subtract within multiples of ten based on understanding place value and basic facts.
