How I Use It
We use this app to support our Bridges Math curriculum. Along with their iOS app, there's also a website that contains the same activity (http://www.mathlearningcenter.org/web-apps/geoboard/). I use this app to support and extend Bridges Math.
Having the same Geoboard available for both tablets and desktop computers makes this app an valuable part of our Math curriculum. I like how the tablet version and website version are the same, so students can easily transfer their knowledge between mobile devices and computers with little or no reteaching required.
