Practice adding numbers in a fun way. Since there are no menus, you do not have to read to use this app. I developed the app together with our 5 year old girl. She knew exactly what she wanted:
When you launch the app, an exercise with two small numbers will appear on top of the screen, f.ex. 2+1=?. Underneath the exercise, a picture of an animal is hidden behind answer cards. When you select the right card, the animal makes its characteristic sound and the card disappears. When you have answered one question for each card, the animal makes its sound three times. Then, a new animal appears with different numbers. After five exercises, the game mode switches to questions of type 2+?=3 and ?+3=5. In this manner you are introduced to solving equations.
After a total of 15 exercises (and animals), the level of difficulty is increased, resulting in higher numbers.
The app is provided free of charge.
