Division as an Unknown Factor Problem

EngageNY
Supporting grades: 3

Description: Students continue to use a variety of factors in this topic as the emphasis in these lessons rests on conceptually understanding division and learning to interpret problems by writing division equations. Students understand division as an unknown factor problem, and in Lessons 4 and 5, they relate the meaning of the unknown in division to the size of groups and the number of groups, respectively. They work through word problems that help give meaning through context and then analyze more abstract drawings. In Lesson 6, students explore division in the context of the array model, interpreting arrays by writing division equations.
