Is it better to by block ice or crushed ice? Use your logical reasoning and measurement skills to solve this challenge that compares surface area of block ice and the same block cut into three cubes. A one page activity from the NCTM...

Do people with big hands have larger angles between their fingers? See if you can find the answer this question when you try this math challenge on estimating and measuring angles. Discover how understanding angles and geometric shapes...

Here are two lesson plans that apply geometric concepts to design objects. The first involves students as a group following step by step instructions on making a kite. After the review of geometry vocabulary, in cooperative groups the...

What lowercase letters read the same both upside down and right side up? If you have the answer, then you can handle this geometric symmetry math challenge. A one-page activity from the NTCM Math Challenge for Families collection....

In this activity, students use the CellSheet Application to determine geometric ratios of areas. Students determine the position of the vertices of a square that has all four vertices on the sides of a larger square and has a specified...

A paper clip is just over 4 cm long. How many paper clips like this may be made from a straight piece of wire 10 meters long? This high level task is an example of applying geometric methods to solve design problems and satisfy physical...

This activity is a tutorial on using the Cabri Geometry application. Students' perform geometric constructions which range from simple triangles to complex conics.

For this task, students investigate why total solar eclipses are rare. They will learn that, in addition to requiring the positioning of the Sun, Moon, and Earth, the Moon can only completely block out the Sun when it is closest to the...

Students must show that they can calculate basic distances, areas and volumes for simple geometric shapes.

In this task, students investigate how many coins will fit around a central coin when they are all of the same denomination, and if there is room left over. The teacher is given a chart of four coin denominations and their diameters, but...

From the San Francisco 49er's Museum Education Program which promotes STEAM concepts, students construct a three dimensional (3-D) artifact stand that is the exact replica of "The Catch" which is 70 inches high. Emphasis is placed on...

Explores derivatives and the idea of infinity using a geometric interpretation of slope.

Mathematicians in ancient Greece were amazed by mathematical patterns, and wanted to explore and explain them. They began to study mathematics just "for fun" without a specific application in mind. One of these mathematicians, Thales of...

Explore different polygons and find their perimeter with this interactive lesson from T.V.411. Students see examples of polygons in everyday life and have immediate feedback to your responses to lesson questions.

Dozens of statistical terms are defined and illustrated in this glossary.

Use this activity to teach students to represent numbers in scientific notation, and use geometry to solve problems related to three-dimensional figures. Explore distance and capacity problems about planets in the solar system. The...

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

Online activities are given to explore space and shape in geometry.

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

This site from the Richland Community College provides the detailed lecture notes to a college algebra course, complete with equations and definitions. Content ranges from "functions and their graphs" to "conics and parametric equations."

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This part...

This interactive worksheet covers such topics as geometry, measurement, number sense, and math in the real world.

Students learn about trigonometry, geometry and measurements while participating in a hands-on interaction with LEGO MINDSTORMS NXT technology. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the...
