Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.
Students explore the concept of area. For this area lesson, students find the area of irregular shapes with right angles. Students break down each irregular shape into multiple regular shapes in order to find the area. Students challenge themselves by coming up with multiple ways to solve each area problem.
In this perimeter and area of irregular shapes worksheet, students use unconventional methods such as using string, dot points, percentages, and more to find the perimeter and area of irregular shapes. Students complete 14 problems total.
Students find the area of irregular shaped polygons. In this geometry lesson, students identify the different shapes of a polygon and use the best method to find the area on a coordinate plane.
Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks found along the Mississippi River.
In this geometry worksheet, students practice estimating the area of irregular shapes. There are 5 questions on this worksheet in which they must estimate areas.
In this irregular shapes activity, 10th graders solve 10 different problems that include determining the area of various irregular shapes as shown in each. First, they divide each figure into familiar shapes. Then, students determine the area of each of those shapes. Finally, they find the sum of the areas.
In this math worksheet, students complete 13 problems where they find the area of irregular shapes where some of the measurements are given. Examples are given in this well-designed worksheet.
In this geometry worksheet, 10th graders determine the area of irregularly shaped figures composed of rectangles, circles, and triangles.  The one page worksheet contains five multiple choice questions and is self checking. 
Students solve for the area of different polygons. In this geometry lesson plan, students identify and differentiate between regular and irregular polygons. They use properties of irregular polygons to solve problems.
Acquaint mathematicians to the concept of probability with a discussion about the results of a game. Then have them play a dice, card, spinner, or coin game and recording the number of wins vs. the number of tries on an interactive web page. Discussion notes and graphics are provided to guide your lecture. At the bottom of the page, there are alternate suggestions and links to related lessons by the same publisher. If you have access to a computer lab, this will add variety to your curriculum.
Young geometers use the interactive website Cyberchase to practice calculating both area and perimeter. Real world problems encourage learners to discover that we use math each and every day. 
Fifth graders estimate the area of an Indian Reservation. In this area lesson students find the approximate area in square miles of Flathead Reservation. The students work with irregular shapes of areas.
Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.
Sixth graders examine the causes of the stock market crash of 1929.  In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the finished product. Lesson is written specifically to South Carolina resources, but can be easily adapted.
Tenth graders explore area of polygons. In this geometry lesson, 10th graders use a geometry utility and a geoboard application to investigate the area of irregularly shaped polygons.
Young geometers use technology (Geometer’s Sketchpad) to explore the Pythagorean Theorem and analyze different proofs. Students work in small groups to gain insight into the relationships of the sides of right triangles by constructing and measuring a variety of right triangles, using GSP to prove the theorem, and solving a number of different problems. 
Students calculate the area of different polygons. For this geometry lesson, students use their knowledge of normal shapes, to find the area of complex shapes. They create their own formulas to find their answers.
Young scholars calculate the area of different polygons. In this geometry instructional activity, students calculate the are given a formula for regular polygons. They create a formula for complex shapes using previous knowledge.
Students explore the area of rectangles. They practice finding area by playing an onliine computer activity where they calculate the area of a rectangle to solve a problem.
