★★★ 3-year-old child...★★★
In early childhood, the ability to discriminate between colors and shapes develops, so it is important to train children to have correct understanding and recognition during this period.
In this app, you will improve your abilities such as "observation", "judgment", "thinking", and "reasoning" through exercises such as "drawing", "meiro", and "connecting lines".
★★★ Features of the app ★★★
[Point 1] With a variety of contents that children will be absorbed in, you can continue for a long time without getting bored.
Includes all 57 questions such as "drawing", "meiro", "connecting lines", "big Sakurabe", "searching for the same thing", "friendship", and "searching for mistakes".

[Point 2] Learn steadily while stepping up little by little
It starts with simple and easy problems, and little by little, elements such as colors and shapes become more complicated.
While stepping up little by little, you will learn repeatedly, so you will acquire it firmly.

[Point 3] Audio narration included for all questions
All questions have audio narration, so there is no need for an adult to read the questions out loud.
Even a child who cannot read letters can use it with confidence.

[Point 4] "Good luck sticker" and "reward medal" function
If you can practice well, you will receive a "Ganbari Sticker". Stickers accumulate in the sticker book and can be checked at any time.
You can also present a "reward medal" to your child who is doing his best.
The “reward medal” is pasted on the top page of the app, motivating the child every time the app is launched.
Encourage your child's motivation and ability with lots of praise.
