Are you looking for a very basic website that will explain the basic properties of a quadrilateral? Use this site to learn about the properties of a square, rhombus, rectangle, parallelogram, trapezoid, and kite. There are also some...

Students learn to derive the formula for the area of a circle. They learn to relate a circle to a parallelogram and rectangle while learning the concept of infinity as they imagine slicing an circle into infinitesimally small slices.

Given a shape, students select from four options the name of the shape. These include more than the basic shapes, such as hexagon, pentagon, parallelogram, and rhombus.

Given composite figures (combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles), students will be able to determine expressions for the area as well as calculate the area of the figure.

[Free Registration/Login Required] In this lesson, young scholars build geometric models of graduation caps using stiff paper. The activity requires the application of skills in finding surface area, understanding similarity, knowing the...

Find a quick, concise explanation of a rhombus. An example is given and clearly explained.

Math Forum provides a set of links to sites that are related to geoboard activities. There are several great links to lessons using geoboards. The links provide insight into how to use them, including how to perform various measurements...

This activity is a based on an activity I saw in Exploring Geometry with the Geometer's Sketchpad. Student will construct a trapeziod and then use rotation to create a parallelogram from the trapeziod. The follow up questions lead the...

In this activity, students can use the USA TODAY Infograph 'Thirsty for oil' to explore the area of a trapezoid and determine how to find area. Students will find the area of a parallelogram and use this to determine a formula for the...

Sixth graders take their knowledge about area of rectangles, squares and triangles and apply it to parallelograms, trapezoids, and composite shapes.

Brush up on your math skills relating to the area of trapezoids then try some practice problems to test your understanding.

This is a very brief look at the rhombus, which is a quadrilateral shape with four equal sides. Features include a JavaSketchpad that allows you to manipulate the shape.
