We are looking for teachers who'd like to create and publish their own learning units tailored to their school's curriculum or to the needs of their classes and individual students. Creating learning units does not require programming skills and we can assist you. Please read our tutorial.

We also need help in translating the user interface and content (which is currently provided in English and German, only) to Spanish, Portuguese, French, Russian, and other languages.

Please contact Gerd Wagner ([email protected]) if you'd like to join our project by creating your own arithmetic learning units, or by helping us with a translation.
