How can we find the area of a parallelogram?

We have been working on this Essential Question all week and our kids our becoming experts on determining area for a given shape! Last week, we worked on area of triangles. This week we have been working on finding the area of parallelograms. A parallelogram has two pairs of parallel sides. I let students explore to see if they could determine the area of a parallelogram given their knowledge of the area of a rectangle. They were able to come up with this: they took one of the triangles on the left side and moved it to the right side to create a rectangle. They were then able to use the formula base x height. So, we determined to find the area of a parallelogram, we need to create a rectangle and then use the formula base x height.
