Area of Irregular Shapes Teacher Resources

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...

In this irregular shapes instructional 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...

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.

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, learners apply this new knowledge to...

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...

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.

Use the formula for the area of a rectangle for more than just rectangles! Scholars see that they can use common area formulas to find the area of irregular shapes. 

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...

Before your scholars know how to multiply side lengths to find an area, give them some practice in simply counting units. They examine shapes that have already been segmented into units, counting them to get the area. There are three...

In this area of polygons worksheet, students 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.

For this area worksheet, high schoolers find the area of one irregular polygon.  Students find the area by dividing the irregular polygon into multiple regular polygons.

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. 

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson plan series supports children with learning how to measure the area of squares, rectangles, and...

What kind of tree does a math teacher climb? A geometry! Here is a lesson that includes all the geometry resources you could ever wish for in one comprehensive workbook. Class members demonstrate what they have learned by...

Students make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

Explore the concept of multiplication by using arrays. Classmates use arrays to gain a better understanding of multiplication. They break arrays apart to model the distributive property of multiplication over addition. The relationship...

Sixth graders examine the causes of the stock market crash of 1929.  For 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...

High schoolers 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.

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...

Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Learners 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.

Students follow written directions to construct their own tangram. In this tangram lesson, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery rhyme. Students also...

Fifth graders use the activities provided on a web site to calculate the area of an object.

The geometry resource investigates the area of irregular shapes. Detailed examples and practice exercises are included.
