Algebra vs. the Cockroaches 
It's you against the cockroaches crawling on your graph paper! 

MathDoku 
At MathDoku you can play this highly addicting logic and math puzzle game. It is available in both online and printable formats for free. Are you up for the challenge? 

Conic Flyer 
This game allows the user to create graphs of conic sections. Using slider bars, one can manipulate the function to change the constant values and view the effects of those changes. 

Adjustable Spinner 
Create a game spinner with variable sized sectors to look at experimental and theoretical probabilities. Parameters: Sizes of sectors, number of sectors, number of trials. 

Data Flyer 
Enter a set of data points, then derive a function to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.


Interactive Quadrilaterals

See all the different kinds of quadrilateral "in action". You can drag the corners, see how the angles change, and observe what properties do not change.


Geometric Solids 
This tool allows you to learn about various geometric solids and their properties. You can manipulate and color each shape to explore the number of faces, edges, and vertices. 

Three Dimensions 
Manipulate solid objects in ways you never could in "real life". These pages on solid 3D geometry collect together interactive resources on the Platonic solids, pyramids, prisms, polyhedra, impossible objects, constructing 3dimensional shapes, isometric views and much more... 

Area of a Circle 
An activity where you measure a circle and the resulting figure when you cut it into wedges and tape them together to form a crude parallelogram. 

3D Transmographer

Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, revolving around any line (which yields a 3D image), rotations about any point, and translations in any direction.
