Polygon
Playground  Explore symmetry, tessellations, and
much more by dragging polygons to create what ever you want:
houses, animals, boats, etc. 
Shape
Creator  An exploration of the concept of shapes,
rotate & flip. Create your own design using the geometric
shapes in the tool. 
Pattern
Blocks  Geometric shapes. Familiarize oneself
with the different shapes, their relations & proportions.
Rotate them, understand symmetry. A tool to learn & practice
fractions. 
Buzzing
with Shapes  2 player game (Practice with 1).
Be the first to fill a row, column or diagonal. Click spinner
& it will tell you what sided figure you need to find. 
Cannon

Pentominoes
 A pentomino is a geometric shape formed by adjoining five
squares with one another edge to edge. There are twelve unique
ways to do this (not counting rotations and reflections).
Those twelve pieces are pictured here and make up the "classic"
set of pentominoes. Traditionally each piece is named using
the letter of the alphabet which most closely resembles its
shape. More

Perimeter
Activity  Computers shows a shape on grid paper
& will ask you what the perimeter of the shape is. It
does it by units only. 
Area
Activity  Computer shows a shape on grid paper
& will ask you what the area of the shape is. It does
it by units only. 
Shape
Space Measures  Upper elementary& middle
school geometry activities. Angles, Grids, shapes & transformation.

Geometry
Workshop  Shape recognition, features of polygons,
slides, flips, turns, angles, triangles, perimeter & area. 
Feed
the Bug  Great practice for understanding coordinates.
Computer gives you coordinates like (3, 5) & you have
to find them.
