The overarching design of this lesson plan and worksheets is to launch students on a brief and somewhat directed explore time on how to decompose and compose a parallelogram in order to discover an efficient way to find area. Lesson Objective: Students will be able to demonstrate that any parallelogram can be decomposed and recomposed into a rectangle, and as such to calculate the area of a parallelogram by multiplying the base times the height. Aligned with Common Core State Standard: 6.G.1

Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
The opportunities for students to verbalize their thinking will really help with understanding and retention.
