Building Geometry : Instructables https://www.instructables.com/featured/ Instructables supports teachers by providing free pro memberships and awesome project ideas for your classroom. We provide plug and play hands-on projects to let you supplement your curriculum with the best projects that other teachers have to offer.
You don’t need to be a traditional classroom teacher to participate, either. If you are an after-school teacher, a scouting leader, a librarian who runs programs, or anyone whose job is explicitly educational, you are invited to participate.
Instructables was officially spun out of Squid Labs in the summer of 2006, and has gone on to grow from a modest hundreds of projects to over one hundred thousand.
The community that now calls the site home, is an amazing mix of wonder from around the world. Every day we continue to be amazed by the imagination, curiosity, and simple awesomeness of everyone who shares their creations with us on Instructables.

Geometry Videos http://www.math-videos-online.com/geometry-videos.html Geometry Videos
Are you looking for free online geometry videos? Each of the following links takes you to an online video on a particular geometry topic.
Some videos are followed by online quizzes and interactive games designed to reinforce the concepts taught in each movie.
The eyeballing game http://woodgears.ca/eyeball/ The eyeballing game
The game works by showing you a series of geometries that need to be adjusted a little bit to make them right.
A square highlights the point that needs to be moved or adjusted. Use the mouse to drag the blue square or arrowhead where you feel it is 'right'.
Once you let go of the mouse, the computer evaluates your move, so don't let up on the mouse button until you are sure. The 'correct' geometry is also shown in green, so you can see where you went wrong.
You will be presented with each challenge three times. The table to the right shows how you did on each challenge each time.
Geometry from the Interactive Mathematics Miscellany http://www.cut-the-knot.org/geometry.shtml Geometry from the Interactive Mathematics Miscellany
A huge collection of geometric problems and discussions, many with interactive Java illustrations.
Mathematics Geometry Tutorials (recommended) http://nlvm.usu.edu/en/nav/vlibrary.html The National Library of Virtual Manipulatives (NLVM) is an NSF (USA) supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis).
The project includes dissemination and extensive internal and external evaluation.

Geometry from the Land of the Incas http://agutie.homestead.com Geometry Step by Step from the Land of the Incas provides an eclectic mix of sound, science, and Incan history intended to interest students in Euclidean geometry. Recent additions include Simson Line (proof of Simson line), The Raft of the Medusa (problem solving with fractals and animation), Archimedes and the Rhombicuboctahedron (Archimedes the Geometer), Sierpinski Triangle and Machu Picchu (fractal illustration), Johnson's Theorem (three equal circles pass through a common point), Varignon and Wittenbauer Paralellograms (quadrilateral: midpoints and trisection points of the edges) and Van Aubel's Theorem (quadrilateral with squares).

Geometric Shapes and Figures : 4 2 Explore http://www.42explore.com/geomet.htm On each page you'll find definitions, activities, 4 good starting points, and many more links and resources for the thematic topic.
In some cases, we've listed more than four websites on a particular topic. For example, we might provide a few for younger readers and others for more advanced learners.
Each school, classroom, and teacher is unique. As such we didn't try to provide specific activities for particular grade levels. Instead we suggest that teachers explore each link, then design specific, developmentally appropriate activities such as discussion questions, small group activities, or webquests to fit the needs of their curriculum.
The links on this site are safe for children.
