Grade 2 Module 4: Addition Within 200 with Word Problems to 100

In Module 4, students develop place value strategies to fluently add within 100; they represent and solve one- and two-step word problems of varying types within 100; and they develop conceptual understanding of addition of multi-digit numbers within 200. Using a concrete to pictorial to abstract approach, students use manipulatives and math drawings to develop an understanding of the composition of units, and they relate these representations to the standard algorithm for addition.
