Students discover building plans and practice reading measurements.  In this architectural design lesson, students investigate the areas of the specific World Trade Center locations that need to be rebuilt and determine the cost....

In this line and angles worksheet, students explore basic geometry vocabulary.  They classify polygons.  Students determine the area and perimeter of given shapes.  They examine the parts of a circle, find volume and...

Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Learners identify the different properties of Euler's Characteristics. In this geometry lesson plan, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.

Students relate topology to polygons. In this geometry lesson, students make the connection between different shapes and topologically equivalent relationships. They use Mobius strips to create and move shapes around.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Studens collect and graph data. In this algebra lesson, young scholars use a CBL and CBR with a TI Calcualtor to observe linear graphs. They use the correct vocabualry as they discuss the collected data.

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

Students measure the angles of wings and tails of various aircraft using a protractor. They estimate and check their measurements. They investigate aircraft being developed and tested at NASA Dryden.

In this rounding money activity, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.

Second graders use a number line to practice subtraction.  In this subtraction lesson, 2nd graders use a number line to count backwards.  Students participate in mad math activities and solve problems.

Students construct a three-dimensional model of the Pantheon.

Students receive a copy of a "Spaghetti Measure" task sheet along with the scoring rubric. Students preview the task and the rubric prior to starting the task. tudeThey determine the circumference of a circle of spaghetti that will...

Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...

Students study the tradional Native American methods of making pottery. They examine the patterns used and design their own pattern that they will use as they make their own pottery utilizing the clay from the surrounding environment.

Fourth graders investigate congruent shapes. In this congruency lesson, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

Students use felt board in the shape of fractions to discover common denominators. They practice adding two fractions together after determining the denominator.

Students conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.

Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

This site gives a description of the geometric mean with a graphical representation. Be sure to use the links to related terms, everyday examples, interactive check point, more information, and challenges involving located in the...

This resource details the geometric mean, giving workable examples for the reader to attempt.

A complete definition of geometric mean in the statistical concept of the word. The discussion includes several examples of how geometric means are calculated and how/where they are useful. Written by Dr. Hossein Arsham.
