Embodiment 1

[0023] The present invention provides such Figure 1-2 The arithmetic training teaching aid shown includes a base 10 and a demonstration board 20 arranged on the base 10 .

[0024] A pair of brackets 11 are fixedly installed on the base 10, the brackets 11 are vertically arranged, and a plurality of mounting holes 12 are provided on the brackets 11, and support rods 21 are provided on both sides of the demonstration board 20 close to the brackets 11 , the mounting holes 111 are interspersed with positioning pins 13 , and the demonstration board 20 is moved up and down to be positioned through different mounting holes 12 . The height-adjustable demonstration board 20 meets the operation needs of children of different heights, and has strong practicability.

[0025] The lower end of the base 10 is equipped with a rotating wheel 30, the base 10 on the outside of the support 11 is provided with a fixed block 40, the base 10 is provided with a counterweight 50, and the fixed block...

Embodiment 2

[0029] This embodiment is mostly the same as Embodiment 1, so the same parts will not be described in detail. The difference between this embodiment and Embodiment 1 is that the number block groups 70 or character block groups 80 of each group are distributed in a circle, and are all connected by connecting rods 130. Fixedly connected on the rotating shaft 100, the end of the rotating shaft 100 away from the connecting rod 130 passes through the demonstration board 20 and is connected with a rotating handle 110, by turning the rotating handle 110 to drive the digital block group 70 or the character block group 80 to rotate, so that different digital blocks Or the character block is aligned with the groove 21 places.

[0030] Working principle of the present invention is:

[0031] First, the L-shaped connecting rod is separated from the fixed block, so that the counterweight is fixed on the ground under the action of gravity, and then the rotating handle is adjusted to combine ...

Abstract

The invention discloses an arithmetic training teaching aid which comprises a base, a support is fixedly installed on the base, a demonstration board of a hollow structure is movably installed on the support, a plurality of grooves are formed in the front end face of the demonstration board, and a plurality of digital block sets and a plurality of different character block sets are rotationally arranged in the demonstration board. Each digital block set comprises a plurality of different digital blocks, each character block set comprises a plurality of different characters, and the digital blocks and the character blocks are rotated to be respectively aligned with different grooves, so that different mathematical operation teaching training is realized. According to the arithmetic training teaching aid, the rotating shaft is matched with rotation of the number block sets and the character block sets, different arithmetic operation questions are formed, meanwhile, operability and interactivity are high, and the arithmetic training teaching aid is convenient to carry and easy to position.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, in particular to an arithmetic training teaching aid. Background technique [0002] In the process of children's teaching, the training of mathematical thinking is essential. In the existing teaching process, teaching is carried out through the teacher's blackboard writing, which lacks interactivity and fun, often gets twice the result with half the effort, and the teaching effect is not obvious; combined with children's understanding of new things Curiosity, combining teaching with hands-on practice, often using teaching aids to train mathematical thinking; the existing teaching aids for teaching thinking training are simply card recognition, which is no different in essence from blackboard writing, lacks flexibility and interactivity, The teaching guidance effect is poor. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the prese...
