Description
Technical field:
The utility model relates to the mathematics teaching instrument field, relates in particular to a kind of arithmetic computation plate.
Background technology:
In primary school mathematics counts learning process, need a large amount of topic that counts of calculation at present, this just need to utilize a large amount of calculus books.And the calculus book majority that the pupil uses is hard copy, whenever is finished one page and just destroys one page, can not reuse, and so not only wastes resource, and has brought certain rubbish.The student in use needs frequent page turning simultaneously, alters again when clerical error occurring, and this needs again certain correction thing, has increased study costs.
The utility model content:
The purpose of this utility model is to provide a kind of arithmetic computation plate, solves the defective of using the hard copy calculation to cause the wasting of resources in the mathematics studying.
The technical scheme that its technical matters that solves the utility model adopts is: this arithmetic computation plate has a sheet frame, and this computing board is furnished with hand-held scrubbing brush; Be inlaid with dark glass in the sheet frame, the dark glass upper surface is provided with write thin film, and dripping between dark glass and the write thin film has moisture film, is provided with the slip film brushing device on the sheet frame, and the brush film bar on the slip film brushing device places between dark glass and the write thin film.Pull the slip film brushing device during use, drive brush film bar and brush flat write thin film, write thin film moisture film effect under be bonded on the dark glass surface, go up writing words in the above with no-water pen, literal can be clearly stayed in the above, when character calligraph is full, film brushing device can be again pulled, refresh write thin film, reuse.
The utility model is used for student's calculation to be write, but easy to use, the Reusability that economizes on resources, that no waste produces, alters is convenient.
Description of drawings:
Fig. 1 is the utility model structural representation.
