Education and teaching appliance used for multiplication tables

Abstract

The invention belongs to the field of education and teaching, and in particular relates to an education and teaching appliance used for multiplication tables. The appliance comprises a base, a supportrod is arranged at the upper end of the base, the support rod is connected with the base through an adjusting mechanism, a cross rod is fixedly connected to the upper end of the support rod, seven damping bearings are rotatably connected to the cross rod, the seven damping bearings are fixedly connected with a first turntable, a second turntable, a third turntable, a fourth turntable, a fifth turntable, a sixth turntable and a seventh turntable from left to right, respectively, numbers from 1 to 9 are carved on the first turntable, the second turntable, the fourth turntable, the sixth turntable and the seven turntable, the computing signs including 'X' and ' / ' are carved on the third turntable, the relational symbol '=' is carved on the fifth turntable, connecting rods are fixedly connected to two ends of the cross rod, and the same background plate is fixedly connected to one ends, far away from the cross rod, of the two connecting rods. For the appliance, by adjusting the relative position relation between a front plate and the background plate, the conversion function of multiplication and division teaching is realized.

Description

technical field [0001] The invention belongs to the field of education and teaching, in particular to a teaching appliance for multiplying formulas. Background technique [0002] The formula for multiplication is a formula table that is easy to remember and used in the enlightenment period of mathematics and the early stage of learning. It has strong practicability. In the current educational and teaching process of mathematics enlightenment and early learning, the education and teaching methods of multiplication formulas are generally carried out by writing on the blackboard or adsorbable stickers printed with digital symbols, and can only perform multiplication operations, which is not flexible enough. convenient. [0003] To this end, we propose a teaching tool for multiplication formula education to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the above problems, and provide an invention template for mul...
