You can master the multiplication ninety 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 is in a quiz format that solves 1 to 5 steps in order.
If you get used to it, please also challenge the mix problem.
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 ninth are written, let's proceed to the next while confirming.
The operation is simple, so even one child is OK.
The sound of this "Ping Pong" will be your child's distinction and 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.
