● 100万ユーザーの知育アプリ開発陣が手がけた中学入試対策の決定版シリーズ第二弾!
● 10年分の有名校過去問を分析し、100問を厳選!
● 中学入試の頻出分野「展開図」をマスター!

◆究極の立体<展開>ってどんな教材?

中学入試算数の頻出分野「展開図」の問題を100題収録し、展開図が組み上がるアニメーションや、わかりやすい解説イラストを通して学ぶ教材アプリです。
100万ユーザーの思考力育成アプリ「シンクシンク」を開発する「花まるラボ」のアプリ教材へのノウハウと、有名学習塾「花まる学習会」の中学受験指導の知見を凝縮し、「展開図から立体をイメージする」感覚を育みます。
過去10年間の中学入試算数で実際に出題された展開図の問題を分析し、パターンを網羅した100問を収録しています。


◆「展開図」はなぜ大事?

ー 明確な解法がない分野。イメージ力が攻略の鍵!
立体の展開図は、明確な解法がなく、イメージ力がモノを言います。実際の中学入試では、大問(*)として出題されることも多く、立体をイメージできないと、大問を全て落としてしまうケースも少なくありません。この分野では、いかにスムーズに展開図から組み上がる立体を思い浮かべられるかが、攻略の鍵を握ります。
(*) 中学入試算数は4-7程度の大問で構成されることが多く、それぞれの大問に通常3-5程度の小問がある。

ー 黒板や紙ではイメージが湧きづらい!
高度な空間認識力、イメージ操作力が求められるため、立体切断同様、身につけるのが難しい分野です。黒板や紙の上では、展開図から組み上がる立体を想像するのは至難の業で、多くの受験生にとって悩みの種となっています。イメージするためには、実際に組み上げてみることが何よりのトレーニングとなりますが、紙に展開図を描いて毎回組み上げていては、それだけで膨大な労力と時間を消費してしまいます。

ー 時間をかけずに、大きな効果!
アニメーションやイラストを通して、イメージトレーニングを短い時間で繰り返し、さらに、立体問題全てに共通する面積・体積計算の考え方もマスターできます。いたずらに問題数を増やすのではなく、マスターするために必要な100問を厳選して収録しているため、中学受験直前の時期でも取り組め、受験生にとって強力な味方となるアプリです。後半の問題では、中学入試レベルを超えたチャレンジ問題も用意しているので、楽しく解き進めるだけで高度な空間認識力やイメージ操作力が身につきます。



◆立体を構成する「6つの基本形」

複雑な立体でも、6つの基本形(三角柱、三角錐、四角柱、四角錐、円柱、円錐)に分けて考えると、たちまち解きやすくなります。
また、この方法は、展開図以外の立体図形問題にも応用できるので、このアプリ一つで、立体図形分野の求積問題にも対応可能です。  


◆本教材の目的
弊社代表・川島の中学受験の指導経験から、頻出にもかかわらず、黒板や一対一のアナログな指導では特に、子どもがイメージしづらく、躍動を感じにくかった立体図形の分野をテーマにしています。
「究極の立体」シリーズでは、アプリの特性を活かし、立体を手に取るように再現しています。そのため、ドリルや問題集などの紙上で、大量の類題をこなしても身につくとは限らない、本質的な考え方を身につけることができます。このアプリを一問一問楽しみながら解き進めていけば、自然と空間認識力が育まれていきます。

◆使い方
・問題選択画面から、プレイしたい問題を選択します。
・プレイ画面右にある6つのボタン(6つの基本形)から、画面下のマスに当てはまるものを選択します。
・全てのマスが埋まったら、GOボタンを押します。
・1問解き終わる毎に、次の1問がプレイできるようになります。

-The second edition of the definitive edition series of junior high school entrance examination measures handled by the educational application development team of 1 million users!
● Analyze the past questions of famous schools for 10 years and carefully select 100 questions!
● Master the “development diagram” of frequent fields in junior high school entrance examinations!

◆ What kind of teaching material is the ultimate 3D?

This is a learning material app that contains 100 questions of "development drawings" in the field of frequent calculations of junior high school entrance exams and learns through animations that assemble development drawings and easy-to-understand illustrations.
Hanamaru Lab, which develops the Think Think app, which develops a thinking ability development application for 1 million users, and know-how on application teaching materials for Hanamaru Lab. Fosters the sensation of “three-dimensional imagery”
Analyzing the problems of the development plan that was actually given in the junior high school trial calculation for the past 10 years, it contains 100 questions covering the patterns.


◆ Why is "development" important?

ー Fields without a clear solution. Image power is the key to capture!
The three-dimensional development does not have a clear solution, and the image power speaks for itself. In actual junior high school entrance examinations, the question is often asked as a large question (*), and in many cases the entire question is dropped if the three-dimensional image cannot be imagined. In this field, the key to capture is how smoothly you can imagine a solid that is assembled from a developed view.
(*) The entry into junior high school often consists of about 4-7 large questions, each of which usually has about 3-5 small questions.

ー It is hard to see images on blackboard or paper!
As it requires advanced spatial recognition and image manipulation skills, it is a field that is difficult to wear as well as three-dimensional cutting. On blackboards and papers, it is extremely difficult to imagine the solids that are assembled from the developments, and this is a problem for many students. In order to imagine, it is the best training to actually assemble, but if you develop the drawing on paper every time and assemble it every time, it will consume a great deal of labor and time.

-Great effect without spending time!
Through animations and illustrations, you can repeat image training in a short time, and also master the concept of area and volume calculation common to all three-dimensional problems. Rather than unnecessarily increasing the number of questions, the app has carefully selected and recorded the 100 questions required to master it, so it can be tackled even before junior high school exams, making it a powerful ally for students. In the second half of the exam, there are also challenge questions that go beyond the junior high school entrance examination level, so you can acquire advanced spatial recognition and image manipulation skills just by happily solving them.



◆ "Six basic forms" that compose a solid

Even a complex solid can be easily solved if it is divided into six basic shapes (triangular prism, triangular pyramid, quadrangular prism, quadrangular pyramid, cylinder, and cone).
In addition, since this method can be applied to solid figure problems other than development drawings, this application alone can be used to solve quadrature problems in the field of solid figures.


◆ Purpose of the materials
Despite the frequent use of our representative, Kawashima's junior high school exams, despite the frequent use of blackboards and one-on-one analog instruction, the theme is particularly in the field of solid figures, which are difficult for children to image and are less dynamic.
In the "Ultimate 3D" series, we make use of the characteristics of the app and reproduce it as if you were picking up a 3D object. Therefore, on a paper such as a drill or a collection of questions, you can acquire essential ideas that you do not necessarily acquire even if you do a lot of themes. If you solve this app while enjoying each and every question, nature and spatial cognition will be nurtured.

◆ How to use
・ From the question selection screen, select the question you want to play.
-From the six buttons (six basic types) on the right of the play screen, select the one that applies to the square at the bottom of the screen.
・ When all cells are filled, press GO button.
・ Every time you finish one question, you will be able to play the next one.
