This document outlines a math lesson on finding the area of parallelograms. The lesson begins with naming different shapes and asking how to find the area of a rectangle. It then explains that the area of a parallelogram can be found by decomposing it into rectangles based on its base and height. Students work through examples calculating areas of various parallelograms. The lesson emphasizes that the area formula is the same for parallelograms and rectangles. It concludes by having students complete an exit ticket question on why the area formulas are the same.
