Grade 3 Mathematics Module 3, Topic E, Overview In Topic E, students begin by working with facts using units of 0 and 1.  From a procedural standpoint, these are simple facts that require little time for students to master; however, understanding the concept of nothing (zero) is among the more complex, particularly as it relates to division.  This unique combination of simple and complex explains the late introduction of 0 and 1 in the sequence of factors.  Students study the results of multiplying and dividing with those units to identify relationships and patterns (3.OA.7, 3.OA.9).  The topic closes with a lesson devoted to two-step problems involving all four operations (3.OA.8).  In this lesson, students work with equations involving unknown quantities and apply the rounding skills learned in Module 2 to make estimations that help them assess the reasonableness of their solutions (3.OA.8).
