Ultimate Shapes

Developing geometrical thinking where students under 12 can improve spatial awareness


Why Focus on Shapes?

Raise globally competitive children

In Japan's widespread collective curriculum, “shape” or “geometry” is taught in schools only during a certain period of time. This is why children can’t develop geometrical thinking which is a sense to work out problems regarding shapes. The subject "shape" frequently appears in the entrance examination both to junior high and high schools. Therefore, "Tamanishiki Ultimate Shapes" was developed to improve geometrical thinking among children. This material is internationally gaining attention and has been used in national schools and prestigious private schools in India.

The Most Required Ability to Solve Shape Problems

Having "a creative mind" helps to visualize shapes in a head

When studying regular math classes or for entrance exams either for junior high school or high school, students often struggle with "shape" problems. What's common among those who feel that they are not good at shapes is that they can't visualize shapes in their head. The ability most needed to solve problems in shape is the "creative mind". Without it, students have difficulty visualizing a three-dimensional image of a shape by looking at a plane surface figure or net. Visualizing the shape in their mind makes the shape problems significantly easier to solve.


テキスト×映像 Text × Video develops “geometrical thinking” utilizing both text and video

“Ultimate Shapes” focuses on developing the brain to visualize shapes. Practicing to visualize shapes in the head will foster “geometrical thinking” so that students can solve problems without formulas. When the structure of the solid shape, revolving shape, and net can't be fully demonstrated with blackboard or text, “Ultimate Shapes” provides video materials that explain the contents, and educate students with confidence in the subject of shape. There are a lot of fun elements included in videos to make students enjoy learning!

Four Features
that Make it so Attractive to Children


Easy to understand because it moves! Solid shapes are animated in our video materials

Students will start to intuitively tell the answers by learning with our videos where the solid shape, revolving shape, and net are animated. Creative Minds are developed from watching videos of a plane shape transforming into a solid or blocks being stacked on each other in the animations.


Visualizing shapes repeatedly helps to solve shape problems. Graded textbooks are optimized according to proficiency

The best suitable level according to the student's proficiency will be chosen among the 10 grades of our textbooks. The spiral method is adopted where contents get more difficult as students progress, so they can build up their skills naturally and they will like to learn the subject in the end. A deep understanding of shapes problems is an advantage when shape problems are a hard subject for entrance exams.


Hint videos are made for each grade. You will see a lot of amazing animations in the video and be able to visualize shapes each time watching it

Suitable hints for each level are provided in the video. They are designed for students to develop their confidence. As such, students will be able to visualize the shapes in their heads and solve problems without hints in future studies.


KIWAMI KIDS from all over the world participating! "KIWAMI Challenge" allows students to check their proficiency on a worldwide level

Our global standardized exam “Kiwami Challenge” is held monthly. As its contents are based on “KIWAMI AAA+”, it is the best opportunity for students to assess their proficiency. Explanations will be added to incorrect answers, so it is a great way for reviewing and further study.

Training for visualizing figures

It is not difficult to visualize a figure. Because the world we live in is all made of 3D. If students consciously visualize figures from a young age, they will naturally develop geometric cognition. Even if they haven't learned it in school, you can encourage your child to become interested in 3D shapes at home. For example, a box of Toblerone chocolates. You can easily show this to your child and say, "This shape is called a triangular prism. See how the bottom is triangle" It's also a good way to train their geometric cognition to imagine how the chocolate fits in the box.


Let the children have an interest in the shapes with familiar objects around them that leads to developing their geometric cognition from a young age.

Developed geometrical thinking can lead to better spatial awareness, which will be essential for coexisting with AI in the future.

While your child's “Geometric Thinking” is being developed, spatial awareness also improves at the same time. Spatial awareness is one of the abilities to imagine things from scratch and visualize the invisible. This is heavily related to the concept of time and creativity and could result in better management skills and creativity. For example, children will begin to think like "I can do this within thirty minutes," or "I can put a chair of this size in this room". All are related and thus, this knowledge can be applied in settings outside of school. "KIWAMI AAA+" focuses not only on teaching knowledge required for entrance examinations but also nurtures spatial awareness, an essential skill for the real world and their future.

A better sense of time and space leads to having a better spatial awareness that is required in social life.

About Tamaishiki Ultimate Shapes


Can I watch the video on a device other than PC?

Yes. You can watch the video materials on a PC or tablet devices like iPad and smartphones. You can access them from home. See the System Requirements.


The contents that are taught seem fairly hard. Can children understand the contents without being left behind?

The curriculum is designed for selecting the grade according to the children's proficiency; not grades at school. They can study at their own pace and build their knowledge and ability comfortably.
