You can master multiplication fun!

Ninety-nine starts from the second grade of elementary school, but it takes time to memorize.
It is important to remember it over and over again.

This application, in order from 1st stage to 5th stage
It is a quiz format to solve.
If you get used to it, please challenge the mix problem as well.

At the beginning, let’s say the problem aloud.
If it is correct, it will sound “bu ~” if incorrect answer “Ping Pong”.
Since the numbers of answers and how to read it are written, while checking
Let’s move on to the next.

Operation is simple, so even one child is fine.
The sound of this “Ping Pong” becomes the child’s distortion
It will lead to the feeling of “I want to do it again!”

The multiplication kettle 's [6 to 9 ladder] is also outgoing free application.
Please use together.

Although it is irregular, I am planning to add problems as well.
