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...

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

In this geometry worksheet, 10th graders determine the area of regular polygons.  The two page worksheet contains eight problems.  Answers provided. 

Students calculate the area of different polygons. In this geometry lesson plan, students find the area for trapezoids, rhombuses and kites.

Using just the measurements of ten rectangles, scholars match them to their calculated areas. Each of these is measured in feet, so the areas are labeled with square feet. The lengths and widths here are double and triple-digit whole...

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

Intended for beginners to geometry, an area of a rectangle problem has scholars draw out the units within the shape. They segment it into four rows and six columns to determine how many squares the rectangle is made of and, eventually,...

Each of these rectangles and squares has the length and width given with units. Can scholars solve for the area? Designed for beginners to this skill, all of these are whole-number single-digit measurements. There is a detailed example...

In this area of polygons worksheet, high schoolers solve 7 short answer and multiple choice questions about area.  Students find the area of triangles given base and height, or points in the coordinate plane.

Tenth graders are provided instructions, including a video, on calculating the surface area of a prism. The one-page interactive instructional activity contains two worked questions. Answers are included. 

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

In this area worksheet, students read and problem solve the area of 8 triangles. Students show their work on each problem on the worksheet.

Use the area of polygons to calculate the area between curves. Pupils calculate areas under income and expense curves by filling the space with squares and right triangles. Using that information, they determine the profit related to the...

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

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

In this surface area and volume worksheet, 10th graders identify and complete 3 different problems that include determining the surface area and volume of cubes. First, they use their ruler to find the width and height of each cube....

Students calculate the area of a parallelogram. In this geometry activity, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

What is the area? Although there are no units involved, beginning geometers will get some good practice as they calculate the area for three rectangles and two squares. They match the answers to a list, however you can easily increase...

Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Here's how to calculate the areas of polygonal figures. In this measuring area lesson plan, upper graders use hash marks to create and count square units. They also problem solve a cyberchase activity watching Quicktime videos.

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...
