Tokyo Shoseki's Mathematics for Elementary School (Grades 1 to 6)

Topics covered

Note: Formal schooling in Japan begins with grade 1.

See sample geometry pages across grade levels

The contents for each grade can be divided into three areas: fundamental geometric figures, the components of shapes, and the viewpoint of analyzing geometric figures (from p. 32 of the Elementary School Teaching Guide).

Note: The links in the table below take you to the pages in the books corresponding to the particular topic.

Grade	Fundamental Geometric Figures	Components of shapes	Viewpoint of analyzing geometric figures
1	Shapes encountered in everyday life of children		Concrete activities such as observation, composition, decomposition, manipulation of geometric figures Position (1D)
2	Triangle, quadrilateral Rectangle, square, right triangle Shape of a box	Line, right angle Side, vertex Face	Component of shapes Equality of sides, right angle
3	Isosceles triangle Equilateral triangle Circle, sphere	Angle Radius, diameter, center	Equality of angles
4	Trapezoid, parallelogram, rhombus Rectangular prism, cube	Plane Diagonal line	Parallel Perpendicular Position (2D, 3D) Nets, sketch
5	Regular polygon Sector	Circumference	Congruence, determining figures Position (2D, 3D) Ratio of circumference of a circle to its diameter (Π)
6	Prism, cylinder Pyramid, cone	Base, side face Axis of symmetry, point of symmetry	Line symmetry, point symmetry Dilation (enlargement, reduction) Front and top view of solids
