## Reflection: Diverse Entry Points Area of Irregular Polygons, Method 2 - Section 1: Do Now

I noticed that some of my students still struggled with the concept of separating the irregular polygon into regular polygons and finding the missing sides.  If they couldn't find the missing sides, they just used the given sides as the dimensions of the rectangles.  I offered these students geoboards so they could move from the abstract measurement of an irregular polygon to a concrete application.  Not only did the geoboards provide a visual understanding of finding the area of an irregular polygon, but they also generated students excitement.

Note: There are several great websites that provide online geoboards for students to work with at home.
