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...

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, students apply this new knowledge to...

Get third graders excited to work find area and perimeter of unit squares, rectangles, and irregular shapes. A 36-page packet comes with task cards, graphic organizers, practice worksheets, printables with squares, exit tickets, and word...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

Examine the surface area of composite figures using an exploratory approach. As a continuation of the previous lesson plan of the 29-part series, young scholars develop plans for finding the surface area of composite figures. Examples...

High schoolers 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.

High schoolers 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.

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...

Pupils 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 measure the perimeter and area of their polygons. In this geometry activity, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

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...

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.

Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.

Students identify nonstandard units of measurement and investigate area of objects. In this geometry lesson, students trace their hands and glue cereal pieces to the print to find the area.

Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.

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

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. 

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...

Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.

Students use Geometers SketchPad to find the area and perimeter of several shapes. For this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

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.
