Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around the pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more.
This virtual version of the manipulative is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPod Touches, iPhones, or iPads.


• Create line segments and polygons by stretching bands around the Geoboard’s pegs.

• Choose from 5 different band colors; 8 band colors on the iPad.

• Fill individual shapes with a transparent color, or use the Fill All button to toggle all the bands between filled and unfilled.

iPad only:

• Switch between the standard 25-peg square board, a rectangular board with 150 pegs, or a circular board with 13 pegs. The circular board enables explorations with angles, fractions, and time measurement.

• Duplicate shapes then move, rotate, or flip them to explore symmetry and congruency.

• Change the color of selected bands.

• Display grid lines with or without numbering to more easily calculate area and identify shape locations.

• Use the drawing tools to annotate work and show understanding

• Write equations and expressions with the text tool.

Great app with one serious lack

This app is great for modeling the use of geoboards for a class. It’s fast, flexible, and realistic—my students can set up the same shapes on their physical geoboards that I do in the app. HOWEVER, it really needs the ability to save shapes so that I don’t lose class time building the models for teaching every time.

So, as a 2nd grader, my Spanish class is working on shapes. She said we had to download this app and practice shapes. She said t’s REALLY fun, too! And guess what? It was! Whoever hates this app, never tried making shapes at least. I just want some updates to the app so it can be more fun.
1. Custom colors! Kids love using different colors and like making small drawings with shapes, so they might need a lot of colors.
2. Saving Projects. I know, some people try it for the first time and their like: “Oh, cool!” And then the next day, they go on the second time and their project isn’t saved. That’s when people get mad. So, please add that.

This app is great, but these were some opinions and suggestions. Have a good day!
