It was created with the assumption that it would be used in individual learning at special needs schools. This is an app that helps you gradually move from counting balls to visual and mental arithmetic. We hope that by doing this repeatedly, you will be able to count the number of balls visually instead of pointing. Even if you make a mistake, the × will not be displayed and you will return to your original location. When you press the hint key, the hint will be displayed dimly. If the answer exceeds 10, the color is changed, and the color changes when the number of balls added becomes 10.
I hope that my children will be able to learn the idea of adding up to 10 and be able to do mental arithmetic.
Finally, in order to increase the children's motivation, I made it display as 100 points.
