1. The technical scheme of the utility model is a math learning toolbox for the sixth grade of primary school, which is provided with a box with a box cover. Different from the prior art, the box body is provided with a cube frame assembly, a cube block, a surface area auxiliary learner, a circular parameter manipulator and a multi-purpose ruler.

The cuboid frame components contained in the box body of the utility model are divided into cuboid frame components and cube frame components; Each frame component consists of 8 3D joints and 12 plastic rods respectively; The cross section of the plastic rod is a regular hexagon. Of course, other suitable structural forms can also be adopted.

The utility model has two sets of cuboid frame components, one of which has square sides. Of course, other suitable numbers and structures can also be used.

2. The cubic block in this utility model adopts centimeter cubic block. Of course, other suitable cubes can also be used.

The surface area auxiliary learner of the utility model comprises a long cube surface area device and a cube surface area device, both of which are composed of the plane development diagram of the corresponding cube. Of course, other suitable structural forms can also be adopted.

The circular parameter manipulator of the utility model comprises a circular plane parameter manipulator and a circular three-dimensional parameter manipulator. Of course, other suitable structural forms can also be adopted.

3. The circular plane parameter manipulator of this utility model is divided into circular perimeter manipulator and circular area manipulator; The manipulator with circular perimeter is a transparent plastic sheet, and the manipulator with circular area is a circular hard paper divided into 16 equal parts. Of course, other suitable structural forms can also be adopted.

The circular solid parameter manipulator in the utility model is divided into a cylindrical surface area device and a conical volume device; They are all made up of the corresponding flat development diagrams of cylinders and cones. Of course, other suitable structural forms can also be adopted.

The utility model relates to a multi-purpose ruler, which is a rectangular transparent plastic template ruler, one side is a centimeter ruler, and the other side is respectively provided with geometric holes. Of course, other suitable shapes and structures can also be adopted.

The geometric holes mentioned in the utility model include circular holes, elliptical holes, rectangular holes, square holes, trapezoidal holes and triangular holes.

The utility model has the advantages of being closer to the content of teaching materials, improving the use efficiency, summing up the experience of previous learning kits and absorbing the valuable opinions of mathematics and teaching and research personnel. According to the deepening of the reform of mathematics teaching in primary schools, the adjustment opinions of People's Education Institute on the textbooks of nine-year compulsory education published by People's Education Publishing House and the existing textbooks for primary and secondary schools, as well as the difficulties and practical teaching needs in the textbooks published by People's Education Publishing House. It can cultivate students' interest in learning, develop students' intelligence, cultivate students' ability to analyze and solve problems, improve classroom teaching efficiency, and help to improve the quality of mathematics teaching in a large area. Easy to use and carry.
