Web Link: Geoboard by The Math Learning Center
Flexibility: This geoboard app has the following features:
There are 8 coloured elastic bands that can be stretch by pulling on any of the sides. The same colour can be used more than once in the geoboard.
There is a 4x4 square, 9x14 rectangle, and 12 point circular geoboard available. A grid and coordinate plane can be turned on so students can follow along or observe lengths.
All three geoboards can be used, the elastics are saved when flipping between them.
Shading can be turned on for each elastic which highlights the area contained by it.
There is a keypad, textpad, and pen for adding information to the canvas.
Each canvas can be saved and shared with students in the classroom using an 8 alpha-numeric code. These are saved for 18 months from last use. Great for making online practice for students.
And, most importantly, the elastic bands will never snap or be shot across the room with finger pistols.
User Interfaces: Mouse and touchpad friendly. Touch-friendly.
Browsers: Works with all major browsers.
Web Link: GeoBoard
Flexibility: This virtual geoboard allows for use of a 9x9 square or a 24 point circle with 4 outside posts. There are 5 colour bands to use, but each colour can be used more than once.
User Interfaces: Mouse and touchpad friendly. Touch works, although some touchpoints are smaller and harder to work with.
Browsers: Works with all major browsers.
Web Link: Geoboard | Free Virtual Manipulatives | Toy Theater
Flexibility: There are a number of features on this geoboard, some of which work well and some that should be avoided.
There are 6 colour bands that can be drawn. Once a band has been drawn it cannot be undrawn without clearing the entire geoboard.
The default is to include shading on the elastic band, this can be shut off.
Shapes can be rotated horizontally or vertically.
There are a number of geoboards to pick from including:
10x10 and 5x5 grids
24 and 12 point circles, including a concentric circle as well
Tangent, cosine, and sine boards
Isometric and triangles.
Several features should be avoided:
Rotation of the shapes results in them losing pin locations.
Zooming out or in on an elastic band does not scale by space between the pins. The new shape will not connect with any new pins.
User Interfaces: Mouse and touchpad friendly. Touch-friendly.
Browsers: Works with all major browsers.
Web Link: Geoboard Area and Perimeter | Math Playground
Flexibility: This geoboard is in an 8x13 rectangle. This rectangle can have a grid and coordinates enabled on it. There are 12 colours of bands of which any can be placed more than once. Selecting colours can be difficult as it requires you to first drag the band out and then select the colour you want it. The area of bands can also be highlighted. There is also a pen to write on the geoboard.
User Interfaces: Mouse and touchpad friendly. Touch-friendly, but requires slow and purposeful gestures.
Browsers: Works with all major browsers.
Web Link: Virtual Geoboard
Flexibility: This geoboard is a GeoGebra widget. It is based on an 11x11 grid. For bands to be added you have to click on each dot that is next in the shape. A shape's original points can be moved, but no more points can be added. There is a pen to write on the canvas. More geoboards can be found in GeoGebra's resource center here.
User Interfaces: Mouse and touchpad friendly. Touch-friendly.
Browsers: Works with all major browsers.

It is possible to change the line thickness and colour
Is it possible to draw lines with parallel and equal ticks on them.
You can change between a rectangular, isometric, or circular peg pattern.
It is possible to turn off the pegs and the grid.
The width and height of the grid can be changed from 2 to 50 and 2 to 25 respectively.
