Pythagoras was created from educational materials that math teachers used to teach figures and solids in an easy-to-understand way. By repeatedly building and breaking things down, you'll naturally develop an understanding of how to create 3D shapes from 2D ones. Includes a step-up "New Curriculum Guidelines-compliant drill" in cooperation with the Japan Mathematics Certification Foundation. You can use Pythagoras to create and understand "congruence" and "polygons and prisms," which appear in upper-grade classes. Target age: 6 years and older Information cited from the internet.
