Mathematics teaching apparatus

Abstract

The invention discloses a mathematics teaching apparatus, which comprises a desk body. The upper surface of the desk body is equipped with a teaching board and two fixation frames. The fixation framesare in L shape; and the teaching board is cooperated with the fixation frames. The side portion of the desk body is equipped with a pen container lifting device. The teaching board is equipped with an angle stable rotation superposition mathematics geometric demonstration device. A light-transmitting plate having an opaque geometric figure rod is combined with an accent light; and the opaque geometric figure rod can shield light, passing through the light-transmitting plate, of the accent light to enable the light to be projected onto a blackboard to form a geometric figure corresponding to the opaque geometric figure rod, so that a standard geometric figure can be formed on the blackboard without manual drawing on the blackboard by a teacher, and it is convenient for students to deepen their understanding. The mathematics teaching apparatus is suitable for teaching.

Description

technical field [0001] The invention relates to a teaching instrument, more precisely a mathematics teaching instrument. Background technique [0002] In mathematics and geometry teaching, teachers often need to manually draw geometric figures on the blackboard, which is convenient for teachers to intuitively understand the geometric structure. Since most geometric figures do not have corresponding blackboard templates, teachers' manual drawing is often not standardized enough, resulting in hand-drawn geometry. The graphics are different from the expected size and shape, which affects the teachers' understanding. And the position and angle of the geometric figures drawn by hand on the blackboard are relatively fixed. When the same figures with different angles are needed, the original ones need to be erased and redrawn, which is very troublesome. Contents of the invention [0003] The object of the present invention is to provide a mathematics teaching instrument, which c...

[0002] In mathematics and geometry teaching, teachers often need to manually draw geometric figures on the blackboard, which is convenient for teachers to intuitively understand the geometric structure. Since most geometric figures do not have corresponding blackboard templates, teachers' manual drawing is often not standardized enough, resulting in hand-drawn geometry. The graphics are different from the expected size and shape, which affects the teacher's understanding

Moreover, the position and angle of the geometric figures drawn manually on the blackboard are relatively fixed. When the same figure with different angles is needed, it is necessary to erase the original one and redraw it, which is very troublesome.
