This is a simple math drill but with multiple reward animations. There is no sound, no reading requirement, no keyboard entry (only button clicks).
The app starts with addition of numbers 1 through 5, then progresses to numbers adding up to 10, subtraction, missing addend, sequences, and greater-than/less-than comparisons.
The child can view her number of correct answers, shown with an emoji for each one.
If the child enters an incorrect answer, a hint image appears. After 2 incorrect answers, incorrect answer buttons become disabled on each further incorrect answer until only one is left.
On a settings page (for adults but with no restrictions) children may be added by name and assigned a level 1 - 3. The name, level and the number of correct answers are stored on your device for future sessions.
The app is free, and there are no ads. No Wi-Fi or cell signal is required.
