Description
Technical field
This utility model relates to a kind of teaching apparatus for mathematics, specifically a kind of space geometry figure demonstrating teaching aid.
Background technology
The course that in space, relation between geometric figure is critically important in being the mathematics class teaching of senior high school period, but be also that a teacher is not easy blunt explanation, student is not easy the course that understands rapidly simultaneously.Such certain situation often occurs, to a certain geometrical issues, teacher thinks the most interpreted from its space imagination being had and fully aware of understands, but because the student in this stage does not the most possess stronger space imagining ability, it is the fuzzyyest to the three-dimensional imagination, understanding, this Resolving probiems is bad, necessarily affects student to the Grasping level of three-dimensional geometric knowledge and learning interest thereof and confidence.
Utility model content
The purpose of this utility model is to provide a kind of space geometry figure demonstrating teaching aid, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of space geometry figure demonstrating teaching aid, including compoboard A, casing, slip lid, compoboard B, compoboard C, compoboard D, magnet A, magnet B, cotton thread, the end of a thread, fixed rotating shaft and magnetic stripe；Described compoboard A is provided with casing；Described casing is provided with slip lid；Described slip lid surface is provided with matsurface；Being connected by fixed rotating shaft between described compoboard A and compoboard B, compoboard A is provided with a magnetic stripe, and compoboard B is provided with two magnetic stripes；Being connected by fixed rotating shaft between described compoboard C and compoboard D, compoboard C is provided with a magnetic stripe, and compoboard B is provided with two magnetic stripes；Described compoboard A, compoboard B, compoboard C and compoboard D are stitched together by magnetic stripe；All being decorated with equidistant line anyhow on described compoboard A, compoboard B, compoboard C and compoboard D, each point of intersection of line is designed with magnet A anyhow；Being installed with several magnet B on described cotton thread, cotton thread two ends are provided with the end of a thread.
As further program of the utility model: described cotton thread is red cotton thread.
As further program of the utility model: the diameter of described the end of a thread is more than the diameter of magnet B centre bore.
Compared with prior art, the beneficial effects of the utility model are:
This utility model can allow student observe intuitively, relation between geometric figure in space；Cotton thread is red cotton thread, and combination figure out can be allowed to become apparent from.Compoboard can be dismantled, and facilitates teacher to carry and deposits.
