Various levels of difficulty http://www.amblesideprimary.com/ambleweb/mentalmaths/protractor.html Ruler & Compass Simulation This application allows you to simulate ruler and compass constructions on the net, either freehand, or for predefined goals going from basic operations to sophisticated ones such as the regular polygon of 17 sides. In most of the cases, there is a solution which you can follow step by step, and/or a hint which explains the idea. http://wims.unice.fr/wims/wims.cgi?session=1V77FB9E9B.5&+lang=en&+cmd=intro& +module=tool%2Fgeometry%2Frulecomp.en&+special_parm=1 National Library of Virtual Manipulatives The NLVM is a resource from which teachers may freely draw to enrich their mathematics classrooms.

Instead of simply supplying definitions and asking the student to engage in mindless practice, our idea is to have the student work through several activities to discover the applications of the Golden Ratio and Fibonacci Sequence. http://www.geom.uiuc.edu/~demo5337/s97b/ Constructing the Golden Rectangle with respect to the Golden Ratio http://jwilson.coe.uga.edu/EMT669/Student.Folders/May.Leanne/Leanne's%20Page/Gold en.Ratio/Golden.Ratio.html Miss K's Geometry Scavenger Hunt This scavenger hunt will send you on an Internet adventure to find a wide variety of geometry topics and information. http://its.guilford.k12.nc.us/webquests/geometry/geometry.htm A Stitch in Time! A Webquest on Quilting Traditions Creating a quilt based on hypothetical instructions that Betsy Ross left behind in her journal guides students through this creative and interactive avenue for exploring geometry standards. By following this WebQuest, students will explore geometric shapes, patterns, and symmetry while creating a unique project that encourages them to integrate all three of these elements. http://chalk.richmond.edu/education/projects/webquests/patterns/ Geometry games and resources online This webpage lists lots of geometry resources. They have been grouped by the subtopics in geometry. Each topic has resources that fit many grade levels. http://www.homeschoolmath.net/online/geometry.php#middle
