A blackboard for primary school mathematics teaching

Abstract

The invention relates to a blackboard, in particular to a blackboard for primary school mathematics teaching. According to the blackboard for primary school mathematics teaching, a standing board is provided, and the blackboard is suitable for writing of primary school students and is diversified in function. The blackboard is characterized in that the blackboard for primary school mathematics teaching comprises moving wheels and the like; a moving frame is arranged on the lower portion of the front side of a blackboard body, and moving grooves are symmetrically formed in the front portion andthe rear portion of the moving frame; clamping holes are sequentially formed in the rear portion of the moving frame from left to right and are located in the upper portions of the moving grooves; the standing board is arranged below the blackboard body, and the top of the standing board is connected with a connecting device; and a fixing device is arranged at the top of the connecting device andmatched with the clamping holes. According to the blackboard, through the effect of the standing board, the dwarf students can write on the blackboard conveniently, the standing board can be fixed tothe front side of the blackboard through the connecting device, the standing board is convenient to move, and thus the students write on the blackboard more conveniently; and the blackboard is provided with a digital board and a straight ruler, thus the students recognize numbers conveniently, a teacher draws lines conveniently, and functions are diversified.

Description

technical field [0001] The invention relates to a blackboard, in particular to a blackboard for primary school mathematics teaching. Background technique [0002] In elementary school mathematics teaching, teachers also need to ask students questions and answer them on the blackboard, but elementary school students are relatively small and cannot write on a taller blackboard. However, today’s blackboards are relatively traditional, not suitable for elementary school students to write, and have a single function, which cannot assist students in learning numbers. When writing on a higher blackboard, students need to use seats to raise it, and then students can do it on the blackboard. Writing, when students get off the seat after writing, because the seat is higher, the students are easy to fall from the seat, thus causing injury to the students. Contents of the invention [0003] In order to overcome the shortcomings of today's blackboards which are relatively traditional,...
