Problems solved by technology

[0003] In order to overcome the shortcomings that ordinary teachers write numbers directly on the blackboard, and some schools cannot see them, resulting in poor teaching quality, and repeating this, students will feel boring and not interested in learning. Technical problem: provide a method that can be randomly given The multiplication of two numbers enables all-round students to see and interact with students, so that students' learning is not boring, and the teaching quality of mathematics teaching is improved.

Abstract

The invention relates to a questioning device, in particular to a primary multiplication questioning device for mathematics teaching. Technical problem: To provide a primary multiplication problem-generating device for mathematics teaching that can randomly give two numbers so that comprehensive students can see the multiplication, and can interact with students, so that students' learning is not boring, and the quality of teaching is improved. The technical solution is as follows: a primary multiplication problem-setting device for mathematics teaching, including a bottom plate, a support rod, a blackboard, a mounting block, a bump, a cover plate, a turning block, a turning rod, etc.; The left and right sides are symmetrically equipped with struts, and a blackboard is installed between the inner middle parts of the left and right sides of the struts, and the blackboard is located directly above the groove. In the present invention, the teacher rotates the rotary block to make the digital block rotate, and the rotation of the digital block makes the number of multiplication change more, and the student can see the digital block through the observation hole to multiply, so that the student is more interested in the calculation problem, indirectly The quality of teaching has been improved.

Description

technical field [0001] The invention relates to a questioning device, in particular to a primary multiplication questioning device for mathematics teaching. Background technique [0002] In mathematics teaching, the teacher will test the students with questions to know the students' learning situation. Generally, the teachers write the numbers directly on the blackboard. Some short-sighted students can't see the questions on the blackboard when they sit in the back row, which leads to poor teaching quality. Poor, in order to make all the students able to solve the problem, the teacher will let the students write in the notebook, in the process, the students will whisper other people's answers, so it is difficult to know the students' learning situation, and repeat this, the students will feel boring, lead to disinterest in learning. Contents of the invention [0003] In order to overcome the shortcomings that ordinary teachers write numbers directly on the blackboard, and...
