A small bilingual math poster that can be used in the bath.
Types and formulas of plane figures.
Waterproof, bath-use poster.
Main terms and shape words, etc., bilingual with English included as much as possible.
Includes a QR code to listen to English pronunciation.
Contains more information than elementary school + alpha in one sheet.
Summary of elementary school shapes.
In addition to basic shapes like triangles, quadrilaterals, and circles, it includes information on angles, sides, sum of interior angles, congruence and symmetry, area, and a list of formulas necessary for middle school entrance exams, packed with useful information.
Including word problems and applied problems, solving questions that require knowledge and sense, first of all, the basics are important.
Just sticking it in the bath allows young children to touch shapes from an early age.
Let's develop a math brain from an early age.
When solving problems with workbooks, math printouts, drills, or school homework, you can check anytime if it's in front of you.
Before word problems become more difficult, review the basics thoroughly while looking at the poster.
Even after graduating from elementary school, learning continues through middle and high school.
Let's confirm and reinforce learning each time with the poster.

Moreover, you can listen to English pronunciation via QR code.
The audio site is on the page.
Since it is not an app, no download is necessary.
You can hear not only shape names but also how to say units of area and volume.
Content useful even for middle and high school students.

Terms that are difficult to explain are also thoroughly explained.
There is also a list of formulas.
For children just starting elementary school, children who have not yet reached learning age, lower grades, or children who are not good at math, the white background parts are in hiragana, and the colored background parts are for upper grades.
Recommended way to use it is to quiz each other like a game, talking about the poster.
Have fun learning with dad and mom in the bath, and make them think "interesting."
An active learning that can be done at home.
It’s also good as a subject for individual study.
Even just copying it into a notebook makes for meaningful solo study.

Let's start poster learning.
Posters can be simply stuck up, allowing you to view a lot of information anytime you like, with the advantage of requiring fewer actions to learn.
There are many learning tools and materials for studying 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 definitely in "books."
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.
