It is safer for children if the ball cannot be taken down, and the number is actually blocked when moving to the number. is it better for children with effective understanding to look at the number

I would like to ask, how did you start this video? Want to learn

Why do you like to design with a round bead now?
There is a sense of design, but it is easy to lose the ball ~ ~ What do children know? It is lucky not to swallow it. Except for the small ball, it seems to be a calculator, which is useless and not convincing enough.
The alarm clock must be protected by lenses, and the hands will be rotten for you without seconds.

The feeling is essentially that addition, subtraction, multiplication and division are not associated with his behavior. It is a calculator with different operation behaviors, and it is only single digits. There is no way to inspire children. It's no different from the nature of a calculator. I just think "slightly" is fun and cute.

This is so similar to Sato's stereo that it can pass the trial?

How to use the alarm clock can say no

This design is great! There are two questions: will the beads run over by themselves and have magnetic attraction? Will children not catch them and swallow them?
