Students explore the concept of geometric symmetry. In this geometric symmetry lesson, students walk around their school and take pictures of objects that demonstrate symmetry. Students use Microsoft Paint to draw the lines of symmetry...

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Students identify basic geometric shapes using Geogebra. In this geometry lesson, students work on a laptop as they explore different geometric shapes. They calculate the area and perimeter of triangles.

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Learners explore geometric concepts using technology. They manipulate the TI to find important math topics. This activity requires a TI-84 or higher.

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

Use Native American tradition to create the context for making different cultural representations of pottery. Practice using geometrical shapes painted on the pottery, research different patterns found on Native American pottery, and...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

Acute angle, line of symmetry, and vertex are a few terms you'll find in a set of 90 flashcards designed to reinforce math vocabulary. Included in the set are two types of cards; a word card printed in bold font, and a...

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Middle and high schoolers identify and analyze fractals and research information using the Internet to locate information about them. They look at fractals in relation to nature and other real world situations. Pupils create several...

Students create double-exposed photographs, poetry, and multimedia presentations to celebrate their Open Court "City Wildlife" unit.

Students examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling to...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students investigate the geometrical concepts of translation, reflection, and rotation. They make different observations looking for the concepts that are displayed in classroom items like floor tiles, carpet designs, and visuals hung in...

Third graders participate in a game in order to review geometric concepts.

Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.

Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

Young scholars create traditional hats. In this visual arts lesson, students design and create traditional hats that highlight animal features, line design, and geometric shapes in the style of the Kwakiutl.

High schoolers perform dilation on various geometric shapes. They also discuss pros and cons of dilation and employ the Frayer Model to study the vocabulary words in this section.
