Middle schoolers examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Third graders measure time and length. Through the use of video and technology, they explore key elements of measurement, such as units and conversion between units. They explore alternate units of measurement and apply measurement to...

Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.

What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...

Fourth graders complete a variety of activities as they study the European exploration of the Midwest, focusing on Indiana. They map the path explorers took, comparing the British with the French. They research why the explorers stopped...

Learners construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Learners use K'NEX materials sets to...

Students are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...

Students make their own seine net to catch fish in the water. In this seine let lesson plan, students follow directions to make the net and then use it in the water.

In this geometry worksheet, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

Pupils define properties of rectangular prisms. In this geometry instructional activity, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Fourth graders explore obtuse triangles. In this geometry lesson, 4th graders make obtuse triangles with paper and scissors. They determine how to find the center of their triangle.

Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.

Young scholars use Geometer's Sketchpad to examine the scale factor when in is applied to the length of a figure's sides. They look at how the scale factor affects the side lengths, perimeter, and area of the figure that result. They...

In this Euclidean geometry worksheet, students determine if planes are parallel or perpendicular to each other. They identify the vector position. This two-page worksheet contains definitions, examples and explanations of how to do the...

Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...

Fourth graders examine the concepts of, draw, and label points, lines, segments, and angles, They draw, label, and identify horizontal, vertical, intersecting, parallel, and perpendicular lines. They complete an associated worksheet that...

Students define slope, and practice finding the slope of lines through given points. They determine the angle of inclination. Students find the relationship between the slope and the tangent of the lines. Students determine special...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Young scholars are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to...

Students play umpire in a baseball game. They video the umpire's calls and then examine the accuracy of a "line call" when compared to a taped record of a ball's exact impact location. They create a transcript of a fictional court case...

Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
