Introduces how to set up and solve simple geometric-figure word problems. Includes advice regarding formulas to memorize.

[Free Registration/Login Required] This flipchart will help students to solve the area for various rectangles on graph paper. It asks the students to define and solve for area using the appropriate formula.

[Free Registration/Login Required] In this lesson students will understand area measured in square centimeters. They will understand and use the formula in words for the area of a rectangle.

The geometry tutorial examines the area, length, and vertices of a trapezoid. Topics include Heron's formula. The activity has several examples with detailed solutions.

[Free Registration/Login Required] This flipchart explores the formula for finding the area of a triangle. Examples and hints are given to help students. A video clip is included, showing how to find the height of a triangle, given the...

In this exercise, students practice volume word problems with cones, cylinders, and spheres. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

This is the second version of a task asking students to find the areas of triangles that have the same base and height. This presentation is more abstract as students are not using physical models. They still determine the area of each...

Mini-lesson takes a look at the definition and shape of a cylinder, cylinder formula, cylinder volume, and cylinder surface area. Try your hand at the cylinder surface area calculator and interactive questions for better understanding.

MathWorld provides a huge mathematics encyclopedia detailing the concepts of geometry, algebra, calculus, discrete math, number theory, and other math topics--complete with formulas, diagrams, examples, and references for thorough...

What is a cone? Find a definition, example images, and formulas for determining volume and surface area.

What is a prism? Find a good definition and several example images, as well as formulas for finding the volume and surface area of a prism given measurements of its base and height.

What is a cylinder? Find a definition, example images, and formulas for determining the volume and surface area of a cylinder if given the radius of the base and the height.

What is a sphere? Find a definition, example images, and formulas to help you determine volume and surface area given the radius.

What is a pyramid? Find a definition, example images, and formulas for finding the volume and surface area of a pyramid if given base and height measurements. Includes a very brief look at a pyramid in Egypt and its measurements.

Students learn about the properties of a square-based pyramid and the formulas for surface area and volume. The learning resource consists of facts and an interactive spinning square pyramid. Includes several multiple-choice questions.

The resource investigates the cylinder. Students learn about surface area, volume, and different types of cylinders. Definitions, animations, formulas, and practice questions are included.
