Understanding meanings of operations and how they relate to one another is an important mathematical goal for students in fourth grade (National Council of Teachers of Mathematics, 2000). Using pictures, diagrams, or concrete materials to model multiplication helps students learn about factors and how their products represent various contexts. The foundation of understanding how operations of multiplication and division relate to one another deepens the understanding of the composition of numbers. Discussing different types of problems that can be solved using multiplication and division is important, along with the ability to decompose numbers. When students can work among these relationships with flexibility, conceptual understanding strengthens. With this said, a group of fourth grade students were introduced to conceptual previews as a new approach of making sense out of multiplication and division so to develop strong images of what happens when numbers are multiplied and divided in small five-minute mini-lessons before the specified unit on multiplication and division.
