Two students are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of polygons....

In this surface area and volume worksheet, students solve 4 short answer and multiple choice problems.  Students find the volume and surface area of cylinders and prisms.

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

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

For this angles of polygons worksheet, 10th graders solve and complete 18 different problems that include determining various interior and exterior angles. First, they determine the measure of various angles described in the first half...

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...

Here you will find a model of a linear relationship between two quantities, the water depth of a channel and the distance across the channel at water level. The cross section of the channel is the shape of an isosceles trapezoid. The...

Upper graders measure the area and perimeter of several items. In this area and perimeter lesson, learners engage in measuring area and perimeter in several scenarios. Full-group instruction requires students to listen to instruction and...

In this area and perimeter worksheet, students compare area and perimeter of pairs of figures, determining which has either the greatest area or perimeter. A reference web site is given for additional activities. 

Third graders create polygons with perimeters of 30 centimeters, use the centimeter grid paper to determine the area of each shape, and organize the shapes to make generalizations from the patterns they see.

Pupils explore the relationship between area and perimeter of polygons.They measure the area and perimeter of regular polygons inscribed in a circle. Learners then discuss how as the number of sides of a regular polygon increase, the...

The interactive lesson featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

In this area and perimeter worksheet, students find the length or area of seventeen figures.  The figures examined are triangles, trapezoids, parallelograms, rectangles, and hexagons.  Some examples and solutions are...

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.

Young mathematicians find the surface area and volume of a square pyramid and a cone. In what looks like a typical activity out of a textbook, you'll find an activity where learners find an unknown measurement of a pyramid or...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

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.

Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by...

Students investigate the concepts of area and perimeter with the use of chocolate bars. They calculate the perimeter and area of different size rectangle chocolate bars and record the statistics. Then students make a visual comparison...

How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...
