Footprints: Take a Step into Estimation
Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; learners use grids to make and explain estimates within low and high ranges.
Students explore the concept of area. In 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.
Perimeter and Area of Irregular Shapes
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.
Irregular Shape Area-Polygons
Students find the area of irregular shaped polygons. In this geometry instructional activity, 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.
Areas of Irregular Shapes
In this geometry activity, students practice estimating the area of irregular shapes. There are 5 questions on this activity in which they must estimate areas.
Area of Irregular Shapes
In this irregular shapes worksheet, 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.
Area Of Irregular Shapes
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.
Areas of Irregular Shapes
In this geometry learning exercise, 10th graders determine the area of irregularly shaped figures composed of rectangles, circles, and triangles. The one page learning exercise contains five multiple choice questions and is self checking.
Gotcha Covered, Pardner!
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.
Exploring Areas of Irregular Polygons
Students solve for the area of different polygons. In this geometry lesson, students identify and differentiate between regular and irregular polygons. They use properties of irregular polygons to solve problems.
Introduction to the Concept of Probability
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.
Estimating the Area of a Reservation
Fifth graders estimate the area of an Indian Reservation. For this area lesson students find the approximate area in square miles of Flathead Reservation. The students work with irregular shapes of areas.
Here is a measurement worksheet in which learners measure lengths in inches, and complete multiplication, division, decimal, and conversion problems. They complete 27 problems total.
Probability and Geometry
Young scholars practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.
The Good, The Bad, The Ugly
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.
Landforms and Mass of Objects
Fourth and fifth graders put different landforms from shortest to longest and solve math word problems related to the land forms. They also solve 19 problems where they complete the mass of objects.
"Picking" Your Way Through Area Problems ID: 8270
Tenth graders explore area of polygons. In this geometry lesson plan, 10th graders use a geometry utility and a geoboard application to investigate the area of irregularly shaped polygons.
Lesson Plan: Pythagorean Theorem
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.
Calculating the Area of Complex Shapes
Students calculate the area of different polygons. In this geometry lesson plan, students use their knowledge of normal shapes, to find the area of complex shapes. They create their own formulas to find their answers.
