Abstract
The utility model discloses a combined mathematics teaching aid. Brace 1 consists of a plurality of linked braces. The ends of a temple 2 are wedge heads 3 equipped with bolt holes 4 consisting of bolt 10 and nut 11. The ends of brace 1 are equipped with grooves 5 provided with slot bores 6 on its upper and lower plate. The ends of a vertical brace 7 are equipped with bolt 8 and matchable nut 9. A plurality of brace 1, the temple 2 and the vertical brace 7 compose into a demonstrating teaching aid for plane geometry and solid geometry. By adopting the said art scheme, the utility model can compose into various models of plane geometry and solid geometry such as triangle, quadrilateral, polygon, pyramid, prism and prismoid to do visible demonstrations for students according to teaching needs. It is simple to make and operate and convenient to carry and stockpile.
Description
Technical field
The utility model relates to a kind of maths demonstration teaching aid.
Background technology
How much mathematical educations mostly are the solid model teaching aid to the teaching aid that the student demonstrates at present, although it is very directly perceived, but because quantity is too many, preserve and put and all need a lot of spaces, and carry also inconvenient, so the teacher is difficult to demonstrate to the student one by one, influences the student like this to geometric understanding, and then influences quality of instruction.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to carry, combined type mathematics teaching aid that can be combined into multiple geometric model.
Technical solution adopted in the utility model is, this combined type mathematics teaching aid, stull is formed by connecting by the little stull of some joints, two of temple is a sphenocephaly, offers bolt hole on it, disposes bolt, nut, two of stull offers groove, the groove upper and lower plates offers slotted eye, and the nut that the two ends of perpendicular support are provided with bolt and match with it is by the demonstrating model of above-mentioned several stulls, temple, perpendicular support one-tenth plane geometry capable of being combined and solid geometry.
Owing to taked technique scheme, thus the utility model according to the needs of imparting knowledge to students, multiple plane geometry and solid geometric patterns such as triangularity capable of being combined, quadrilateral, polygon, pyramid, prism, terrace with edge are done ocular demonstration to the student.Make, operation is simple and easy, carry, seasoning is convenient.
