Foundations of Multiplication and Division

EngageNY
Supporting grades: 2

Description: Grade 2 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 can serve as units. In Topic A, students begin by making equal groups using concrete materials, learning to manipulate a given number of objects to create equal groups, and progress to pictorial representations where they may begin by circling a group of 5 stars, adding 5 more, then adding 5 more. By the end of Topic A, students draw abstract tape diagrams to represent the total and to show the number in each group as a new unit. Hence, they begin their experience toward understanding that any unit may be counted. This is the bridge between Grades 2 and 3. Grade 2 focuses on the manipulation of place value units, whereas Grade 3 focuses on the manipulation of numbers 1 through 10 as units.
