Online Activities
Tangrams - Form a given animal or object with geometric shapes. Puzzle.
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 Math - Fun game where students explore the idea of angles & force. Sounds complicated, but is for second, third & fourth graders. Mixes simple addition. Try it!
Tessellation Exploration - Several activities to explore tessellations. Start by putting people of the town in a row & move on to houses, trees, etc. At the bottom there are more games.

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.

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.
