This document is a conceptual multiplication lesson plan that teaches students how to use arrays to solve multiplication problems. In the lesson, the students worked with concrete manipulatives, repeated addition, and skip counting to begin to understand how multiplication arrays work. The variety of ways I built out their concept of multiplication allowed for multiple points of entry into the content--making it more likely that each student would find a strategy that worked for him or her. Additionally, the lesson highlights my use of formative assessments to make data-based plans for future teaching. In my own classroom, I will continue to teach math in a conceptual way that demonstrates many different strategies, because I believe such instruction helps kids truly understand the principles behind the math, instead of just memorizing a procedure.
