Kali For younger kids: Even the youngest children create symmetrical artwork based on the 17 tiling groups. Any child who can use a mouse can use Kali. No reading required. Every work is a masterpiece! For older kids: Diving deeper, high school and college geometry students may systematically explore the wallpaper, frieze and rosette groups. Kali’s Show Singularities command along with its Conway and IUC notation provide support for a theoretical analysis.

SpeedCrunch Portable keyboard-oriented scientific calculator SpeedCrunch Portable is a keyboard-oriented scientific/algebraic calculator packaged as a portable app so you add up some quick sums or process advanced calculations wherever you go. You can place it on your USB flash drive, iPod, portable hard drive or a CD and use it on any computer, without leaving any personal information behind. Version 0.12 for Windows, Multilingual 9MB download / 27MB installed (Details) - Support's development and hosting SpeedCrunch Portable works best with the Platform

Relational Relational an educational tool to provide a workspace for experimenting with relational algebra, an offshoot of first-order logic. It provides GUI that can be used for executing relational queries, and also provides a command line interface. Provides a standalone Python module that can be used for executing relational queries, parsing relational expressions and optimizing them. The UI now implements sessions and remembers where you left off the previous time. It was also redesigned to be able to fit smaller screens. The release also fixes some bugs in the parser and in the outher join functions.

Plane developments of geometric bodies (1): Nets of prisms A right prism is a polyhedron that has two congruents pararel polygonal faces (bases of the prism) and with all remaining faces are rectangles. The main interest of this page is to see how a right prism can be developed into a plane net. There is a platonic solid that is a prism, the cube. This is a cube net: The lateral surface area of a prism is the sum of the areas of the rectangles that form the faces that are not bases of the prism. We can calculate the lateral surface area of a right prism (p is the perimeter of a base and h is the height of the prism):

Massive open online course Poster, entitled "MOOC, every letter is negotiable", exploring the meaning of the words "Massive Open Online Course" A massive open online course (MOOC /muːk/) is an online course aimed at unlimited participation and open access via the web. In addition to traditional course materials such as filmed lectures, readings, and problem sets, many MOOCs provide interactive user forums to support community interactions among students, professors, and teaching assistants (TAs). MOOCs are a recent and widely researched development in distance education[1] which were first introduced in 2008 and emerged as a popular mode of learning in 2012.[2][3] Early MOOCs often emphasized open-access features, such as open licensing of content, structure and learning goals, to promote the reuse and remixing of resources.

C.a.R. - News Compass and Ruler - Construct and Rule C.a.R. simulates constructions with a pair of compasses and a ruler on a computer. By moving basic points, students can experience changes in the construction, check the construction for correctness. Moreover, tracks of points or polar sets of lines can be generated to establish new conjectures and gain geometrical insights. Algebrus Algebrus software along with the specially developed XPascal scientific programming language is rich on computational capabilities and has plenty of features that make any kind of calculations fast and easy. It could be as powerful as an expensive software for mathematical calculations or as simple as small "evaluate-while-type" expression calculator (in the compact console mode). And now it is FREE! Important: under Windows 8 or higher the software needs to be launched "as administrator". XPascal programming language

GNU Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Waterman Polyhedra Play with the controls! Use the "Sequence" slider to step through the series of polyhedra. Click the "Colors" button. If you have red-blue 3D glasses, change the "Stereo Mode" to "Anaglyph".

Future of Education: Breaking The Connection Between Learning and Assessment - Epic 2020 It is the best of times. It is the worst of times. Let's find out. Sal Khan The road to 2020 began in 2009. Kig Description Kig is a program for exploring geometric constructions. It is meant as a better replacement for such free programs as KGeo, KSeg and Dr. Geo and commercial programs like Cabri. Kig is free software, as in "free speech". This basically means that you do not have to ask my permission to use it, to improve it, to distribute or even to sell it.

Gmsh: a three-dimensional finite element mesh generator with built-in pre- and post-processing facilities Christophe Geuzaine and Jean-François Remacle Gmsh is a 3D finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh's own scripting language.

Multiples and Factors In this activity, students identify multiples and factors and solve problems that involve finding highest common factors and lowest common multiples. Students will need a good recall of multiplication basic facts in order to be able to do these activities. Activity One and Game
