Grade 1 Mathematics Module 6, Topic A

children at school

Topic A of Module 6 opens with students exploring one of the most challenging problem types for their grade level, comparison word problems (1.OA.1). Students were informally introduced to the problem type in Module 3 as they analyzed data and compared measurements. During Module 5, students worked with comparison contexts through Application Problems. It is with this background that teachers can make informed choices during Module 6 to support students in recognizing and solving comparison word problems. In Lesson 1, students work with compare with difference unknown problem types using double tape diagrams. They then carry their understanding of double tape diagrams into Lesson 2 to tackle compare with bigger or smaller unknown problem types. Throughout the module, students continue to practice these problem types as they solve Application Problems in the topics that follow.
