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.
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.
In this irregular shapes learning exercise, 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 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.
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.
Young scholars 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.
For 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 math learning exercise, 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 learning exercise.
For 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.
What a fantastic resource! The class practices finding the area and perimeter of various regular and irregular shape by first counting the grid squares inside each shape, and then by using the traditional formula. The process is fully explained along with multiple examples and problems to do as a class. Six related worksheets are included. Note: While this is a PowerPoint, the worksheets can be printed.
Young scholars investigate surface area. In this Algebra I/Geometry instructional activity, students analyze and collect data to find the surface area of an irregularly shaped object by relating area to mass. Young scholars use technology to create a scatter plot of the data and determine the line of best fit.
A wonderful resource just waiting to be used. Provide learners with a complete explanation on how to calculate the area of a rectangle. After this process is covered, they will see how they can use rectangles to calculate the area of various irregular shapes. A very important skill.
Wow, that's a big pencil box! Scholars measure the area of a 15-foot pencil box among other measurement word problems. For each, they evaluate the information given to figure the area, which is sometimes not the end-all answer they are seeking. Two problems simply give an image of an irregular shape, asking learners to find the total area. There is a list of answers they match to, however none included the units. If you show these answer options, be sure kids add units to make them complete.
In this area of polygons worksheet, learners find the area of 12 polygons. Each shape is drawn on a grid. The area of each square on the grid is given. Problems are all multiple choice.
Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
In this area worksheet, students find the area of one irregular polygon. Students find the area by dividing the irregular polygon into multiple regular polygons.
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.
