What do students already know about geometry? What gaps do students have in their understanding? Students take the Unit 7 pretest in order to inform instruction.

Geometry concepts are briefly discussed at this site, including volume of a cylinder, parallelograms, circles, trapezoids, and triangles. Sample problems and applications are included for practice.

These interactive activities are designed to examine the mathematical concepts of area, perimeter, surface area and volume. These activities may be used to develop students' understanding of these mathematical concepts.

At the end of this lesson plan about formulas, students will be able to identify and apply the correct formula for a given situation, solve for any unknown component of the formulas for perimeter, circumference, and area of regular and...

This resource allows users to test their geometry knowledge.

This page brings you to a table of contents of three-dimensional figures. Selecting a figure will bring you to a page defining and illustrating the figure with applicable formulas listed.

This CoolMath resource provides an introduction to some Precalculus formulas.

WebMath will calculate the side length, diagonal length, perimeter, area, or volume, given the side, perimeter, diagonal, or area. This site also displays formulas for a square.

Gives basic info about a right triangle. Also students can substitute values for sides or angles in order to find missing values. The method for solving is then explained.

[Free Registration/Login Required] In this lesson students test their understanding of algebra and geometry problems with a series of engaging quiz questions.

This site contains an extensive list of various units of measurement known internationally and across several disciplines. Unit symbols are also included.

The resource consists of comprehensive learning tools such as class notes, video lectures, and templates through which students can review prealgebra topics.
