Problems solved by technology

[0002] In mathematics teaching, there are many abstract mathematical theorems. These theorems are generally abstract and require students to understand. It is difficult to show students intuitively through theoretical teaching. For example, mathematical theorems such as the Pythagorean Theorem, teachers simply The effect of theoretical teaching is not ideal. If students can understand more intuitively with the help of auxiliary teaching aids, the teaching effect will be better

Embodiment 1

[0024] Such as figure 1 As shown, a teaching aid for improving mathematical thinking includes a right-angled triangular prism 1, a cuboid 2 is respectively fixed on three sides of the right-angled triangular prism 1, and the upper surfaces of the three cuboids are all square right-angled triangular prisms 1 and the top surface of cuboid 2 are made of transparent glass or plastics.

[0025] The length value of the side length of cuboid 2 is equal to the width value of its corresponding right-angled triangular prism 1 side respectively, and the height of cuboid 2 is equal to the height of right-angled triangular prism 1, and right-angled triangular prism 1 and cuboid 2 are hollow structures, three The rectangular parallelepiped 2 is connected with the right-angled triangular prism 1 respectively, and the wall thicknesses of the rectangular parallelepiped 1 and the rectangular parallelepiped 2 are equal. A fluid 3 is provided in the cuboid 2 and the right-angled triangular prism...

Embodiment 2

[0027] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that it also includes a fixed bracket 4, a rotating shaft 5 is fixed on the bottom surface of the right-angled triangular prism 1, and one end of the rotating shaft 5 is fixedly connected with the bottom surface of the right-angled triangular prism 1, and the rotating shaft 5 The other end of the rotatably connected with the fixed bracket 4. The fixed bracket 4 can make the right-angled triangular prism rotate around the rotating shaft 5, so that the fluid 3 flows from the cuboid corresponding to the hypotenuse of the right-angled triangle into the cuboid corresponding to the two right-angled sides, or flows from the cuboid corresponding to the two right-angled sides into the cuboid corresponding to the hypotenuse. inside the cuboid.

Embodiment 3

[0029] Such as image 3 , Figure 4 with Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the right-angled triangular prism 1 and the cuboid 2 corresponding to the hypotenuse of the right-angled triangular prism are in an integrated structure, and the right-angled triangular prism 1 and the two right angles of the right-angled triangular prism The cuboids 2 corresponding to the sides are detachably connected. The corresponding sides of two right-angled sides of right-angled triangular prism 1 are provided with chute 6, and the cuboid 2 corresponding with right-angled side is provided with the slide rail 7 that cooperates with chute 6, and cuboid 2 is by slide rail 7 and chute 6 and The right-angled triangular prism 1 is detachably connected. Connecting holes 8 are provided on the sides corresponding to the two right-angled sides of the right-angled triangular prism 1 , and detachable hole caps 9 are provided on the connecting holes 8 . Wh...

Abstract

The invention discloses a teaching aid for improving mathematical thinking. The teaching aid comprises a right-angled triangular prism, wherein the three side surfaces of the right-angled triangular prism are respectively and fixedly provided with a cuboid, and the upper surface of the cuboid is square, and the length value of the side length of the square is equal to the width value of the side surface of the corresponding right-angled triangular prism. The height of the three cuboids is equal to the height of the right-angled triangular prism, and the right-angled triangular prism and the cuboids are of hollow structures. The three cuboids are respectively communicated with the right-angled triangular prism, and fluid is arranged in the cuboids and the right-angled triangular prism, andthe volume of the fluid is equal to the volume of the cuboid corresponding to the bevel edge of the right-angled triangular prism. The teaching aid can vividly and visually represent the Pythagorean theorem in mathematics by adopting a simple structure, so that students can conveniently understand the Pythagorean theorem. The vividness of teaching is improved, and the inconvenience of teachers during teaching is relieved. The study idea of the students is facilitated, the ability of mathematical thinking is improved, and the thinking of students is opened.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an auxiliary teaching aid for improving mathematical thinking. Background technique [0002] In mathematics teaching, there are many abstract mathematical theorems. These theorems are generally abstract and require students to understand. It is difficult to show students intuitively through theoretical teaching. For example, mathematical theorems such as the Pythagorean Theorem, teachers simply The effect of theoretical teaching is not ideal. If students can understand more intuitively with the help of auxiliary teaching aids, the teaching effect will be better. Displaying theorems through the image display device can inspire students' learning ideas, improve the ability of mathematical thinking, and open students' thinking. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the object of the present invention is to provi...
