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.

Students study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...

Learners estimate the area of states using the formulas for the areas of rectangles, squares, and triangles. In this geometric shapes instructional activity, students divide irregular shaped states into shapes. They use the formulas for...

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

Young scholars explore the concept of area. In this area lesson plan, students find the area of irregular shapes with right angles. Young scholars break down each irregular shape into multiple regular shapes in order to find the area. ...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

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. 

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

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 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, students find the area of one irregular polygon.  Students find the area by dividing the irregular polygon into multiple regular polygons.

For this geometry worksheet, students find the area of squares, rectangles, and non traditional shapes. Students complete 5 problems on this worksheet. 

In this composite figures worksheet, students solve twelve short answer problems. Students find the area of figures composed of various polygons given a sketch of the figure with side lengths labeled.

In this area worksheet, learners find the area of ten figures that are drawn on a coordinate grid. Five of the shapes are triangles. Five shapes are irregular quadrilaterals.

Students engage in a study of the mathematical concept of calculating area in regular and irregularly shaped objects. The area is practiced by producing maps based upon the idea of creating a nature preserve for wild tigers. This makes...

Students explore measurements by analyzing geometric shapes. In this surface area instructional activity, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons....

Young geometers need a clear understanding of perimeter, volume, and area. This instructional activity provides a worksheet to help small groups of learners to calculate various measurements of objects and choose the proper units for...

In this finding area worksheet, learners solve the area of an irregular figure by reading and performing step by step operations. Students complete fourteen steps to solve and summarize finding the area.

In this math activity, students find the areas of a triangle, rectangular box, and the irregular shape. They take a portion of the area away from the source block.

In this math worksheet, middle schoolers find the area of the triangles, the perimeter of the irregular shape, and the diagonal of the cube.

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.

Fifth graders find the area and volume of buildings. In this architecture lesson, 5th graders look at the drawings of three historic Tennessee buildings. They use these to help find the area and volume of the building. 

Students graph polygons using the name and number of sides. In this geometry lesson, students identify the formula to calculate the area and perimeter of polygons. They relate the formula to different polygons and shapes.
