Read full description

This application is developed for children between 3 and 6 years old. They can practice preparatory reading, counting, calculating, number recognition, and much more. Many goals for primary school education can be practiced with this application. This application has been designed for children between 3 and 6 years old. Most children cannot read yet, so all explanations, questions and assignments are spoken out loud. So the children can work independently with this application. The clear, bright and beautifully designed application enables the children to practice the assignments faster and better, because they can play the game by themselves. By visiting the settings menu, the teacher or parents can disable or enable various parts of the application or change the settings of the games. For example, you can able practicing numbers until 5, 10, 15 or 20 and you can select how many assignments are to be done before the final score is shown. Kind regards, Teacher Dennis
