Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

In this math worksheet, middle schoolers find the area and perimeter of the regular and irregular polygons. They pay attention to use the proper measurements for calculation.

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 Pick's Theorem learning exercise, students solve and graph 6 different problems that include using Pick's Theorem to solve. First, they use Pick's Theorem to determine the area of the shapes given as well as their own shapes...

Activate your geometer's minds with area calculations, some of which are tricky. First, they solve five word problems dealing only with rectangular shapes. The next five use irregular shapes with side measurements given. Scholars solve...

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.

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Shape one's understanding of geometry using the resource. The sixth of seven chapters in 6th Grade Math focuses on geometry principles. Future mathematicians learn to find the area of parallelograms, trapezoids, triangles, and other...

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...

In this perimeter learning exercise, students find the perimeter of given regular and irregular polygons. This four-page learning exercise contains 20 problems. This interactive learning exercise may be completed online or printed for...

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

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...

Introduces the concept of regular polygons along with regular polygon examples, not regular polygons, irregular polygons, and area of a regular polygon. Check-out the solved examples for better understanding and try your hand at solving...

Learn how to use coordinates to calculate the area of an irregular polygon.

Get the definition and properties of a polygon. Then explore such topics as: 1) types of polygon 2) area 3) Perimeter 4) angles associated with polygons and 5) names of polygons.

Find a definition of regular polygon, and learn how to calculate the internal angle, external angle, and number of diagonals of a regular polygon. Also, learn how to find the area of regular polygons.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students to calculate the area and perimeter of regular polygons. Students examine guided notes, review guided practice, watch instructional...

Practice finding the areas of complex shapes that are composed of smaller shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This site provides the user with a useful reference to different geometric forms, their elements, formulas, and areas. Entirely in Spanish.

This lesson focuses on quadrilaterals which can fall into multiple categories based on the number of sides and the angles.
