Remember my recent post on GeoGebra, the innovative and open source mathematics learning software that has attracted a global community of school teachers? GeoGebra is the best interactive software for explaining and teaching mathematic examples. And the best thing is that you can get and distribute GeoGebra for free.
Now the creators of GeoGebra started a Kickstarter pledge for porting this cool piece of software to the iPad platform.
We want to make GeoGebra available for the iPad. An html5 version of the software is already available and partly working on tablets without Java. But this is not enough, we want a real iPad Application. A GeoGebra app free to download for everybody from the Apple AppStore.
The reason why we want to keep the iPad application free is because GeoGebra itself is free and keeping it so we want it to be available for everyone. If we reach the desired 10,000 dollars, we can support the development.
I think the team around GeoGebra really deserves a huge crowd of backers for their enthusiasm to bring maths and MINT topics to children wordwide!
Before we leave the topic of Sierpinski Tetrahedra, with which many Math Mondays have been concerned, I wanted to highlight the story of one particularly impressive Sierpinski Tetrahedron which has indirectly inspired a host of young makers.
Namely, it’s this record-setting order-seven “Rainbow Tetrahedron,” built in Cleveland in 2002:
Math Mondays have so far featured a wide array of different items from which one can make a tremendous variety of geometric constructions, but there has not yet been one on hula hoops. This week and next we’ll remedy that oversight. Also, the postings so far have almost entirely shown the constructions as fait accompli, so this series will also try to give a bit of insight into the process of devising a new creation.
Total structural collapse, leading to hula chaos! What to do?
Some ideas have the power to change the way we are thinking about everyday technology and knowledge. For me GeoGebra is such an idea which has a really positive effect on how we are teaching basic and advanced mathematics to children and adults. The idea behind GeGebra is to provide a powerful open source software for visualizing mathematic topics in a very intuitive and understandable way. Over the last years hundreds of mathematic teachers worldwide created a GeoGebra community which shares mathematic examples and new ideas for the further development of this genious framework. The team that developed GeoGebra has already won several prices for their incredable work. GeoGebra offers interactive graphics, algebra and spreadsheet and a lot of free learning material from elementary school to university level.
