With this app, children are led to playfully learn the correct spelling of the numbers. This app is suitable in the school environment as well as at home. Your child will be supported by individual visual feedback in the app in the learning progress. The design of the app is child-friendly and encourages learning in a fun way. For each number, the corresponding number is shown by means of a dice image to illustrate the meaning of the number. This allows the child to early associate the symbolic notation with the iconic representation. Thus, the written numbers are not purely abstract and meaningless for the child but are linked from the beginning with the appropriate quantity. This is essential for the creation of number concepts. The writing flow of the child is supported by small flying bees. If a child tries out their own writing path, it receives individual feedback and insight into their own learning progress. Based on the results stored in the app, the child can see their own progression. No personal data is stored outside the device. The app recognizes the country code of the device and uses the correct glyphs for the country.
