Complex Area Problems

Description:

This two-part lesson requires students to use a variety of math skills, including measuring distance, finding the area of complex polygons, and solving word problems involving rates. The first part has students find the area of a complex shape using formulas and the Google Earth ruler tool. The objects chosen for this lesson are several crop fields in Minnesota, but you can use what you want. The second part of the lesson has students use the house icon in Google Earth to focus on a problem or several problems that a farmer may want to solve, such as "how much money will my crop yield?" Students will need to be able to solve rate problems with a proportion for this section.

Geometry

Solve real-world and mathematical problems involving area, surface area, and volume.

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.
