Students build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Students describe the reflection of rotational symmetry...

Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

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

Students complete worksheets involving rotational symmetry. In this geometry lesson, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine the relationship...

Students create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...

Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle instructional activity, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...

Learners study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Scientists have been studying exothermic reactions before they were cool. The lesson plan begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed...

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

Students are introduced to the topic of congruence and proportions in Geometry. Using technology, they construct and validate the properties of various geometric figures and identify whether it is congruent or proportion to the objects...

Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.

Students investigate triangles. In this shapes geometry lesson plan, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections...

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Students examine geologic time to scale. In this geologic time lesson, students create a time-scale metaphor that shows some of the Earth's important events. Students present their metaphor to the class.

Fourth graders explore polygons. For this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Second graders, using a minimum of four space figures, create a mobile. They use a "Draw" program to first plan out their figure.

Second graders create a Geo-Folder based on geometric terms and concepts. They make a Table of Contents that guides them through the process of assembling a folder of completed activities.

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

In this area instructional activity, 6th graders take a pre-test about what they may already know pertaining to geometric area.   Students respond to 10 multiple choice questions.

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.

Students recognize that quilts are created by geometric components. They examine how quilts are an artistic art form that show the cultural heritage of the people who make them.

Pupils listen to a poem that includes directions to use geometric figures to complete a creative task.
