Geocadabra can help the child to understand difficult objects. Especially 3D objects can be rotated, unfolded, and calculations can be done. Geocadabra is also dynamical: points, lines and circles can be dragged with the mouse. While dragging a point, the status of the object keeps the same: a midpoint will be a midpoint, also after dragging an endpoint of an edge.

Geocadabra is used nowadays in Holland and Belgium, but it is also available in English, it runs at schools in South Africa and Texas (Houston).

I am searching for more schools and pupils in English speaking countries, where Geocadabra can help understanding mathematics. Using the internet, I will support the school from distance.

Geocadabra can simply be downloaded from its website. After installing it, it will behave as a demo. But on the website you can request an autorisation, by entering your email adress (after clicking "register"). Then immediately the autorisation is emailed to you.

Of course teacher and pupil can ask me questions. Simply by emailing me the question. Together we can approve the software, when you email me your suggestions to change Geocadabra.

Geocadabra can be downloaded from

On this site also several documents can be downloaded to help the child and teacher to use and understand the software.

On my Dutch privat website, http://home.planet.nl/~leclu012, more materials can be found for Geocadabra.
