For children just starting elementary school, children who haven't reached learning age yet, lower grades, and children who are not good at math, the white background parts are in hiragana, and the colored background parts are aimed at higher grades.
Recommended use is to quiz each other like a game, talking about the poster.
Enjoy learning with dad and mom in the bath, and make them think "It's interesting."

Let's start poster learning.
Just sticking the poster up allows you to view a lot of information anytime you like, with minimal actions needed for learning, which is a big advantage.
There are many educational tools and materials for learning shapes.
Shape puzzles, shape rulers, shape encyclopedias, and various reference books.
Tools like puzzles and rulers are good because you can actually hold them.
However, the information obtained from them is limited.
If you want to learn formulas, the basics are still "books," right?
Shape encyclopedias and reference books contain a lot of information, and many interesting ones are published.
But books require actions like "picking up" and "opening".
In contrast, posters can be simply stuck up and studied anytime you want.
